Niels Bohr, the Bohr-Rutherford atom and Balmer series, take 2

Niels Bohr, 2nd edition, 11" x 17" linocut print, 2018 by Ele Willoughby

I've just printed a new edition of my portrait of quantum physicist Niels Bohr (1885-1962). One of his most famous contributions to quantum mechanics was the Bohr-Rutherford model of the atom. Bohr is shown next to the Bohr model of the Hydrogen atom (all the concentric circles are actually at the appropriate spacing, proportional to the n squared, which probably reflects on my sanity in some way). Bohr proposed that the orbits of electrons were somewhat like planetary orbits (though circular, and at specific quantized distances). To explain how orbitting charged electrons didn't lose energy and annihilate spectacularly with the so-called "spiral death" (physicists are big on melodrama, I'm telling you), he stipulated that perhaps they simply weren't allowed anywhere but the specific orbits. They could lower their energy state if excited by falling to a lower orbit, giving off a specific photon of a specific colour related to the difference between energy levels. This also explained how the spectra of gases had distinct, thin, spectral lines. I've illustrated this with the Balmer series - because it is composed of lines which are visible to the eye (H-alpha is red and caused by a jump from the 3rd to 2nd orbit; H-beta is cyan and caused by a jump from the 4th to 2nd orbit; H-gamma is indigo and caused by a jump from the 5th to 2nd orbit; and H-delta is violet and caused by a jump from the 6th to 2nd orbit). I've shown both the quantum jumps (squiggly arrows - squiggly lines are tradition for photons) and by the line spectrum below Bohr.

Confession: In the first edition, the model of the atom was behind him. It turns out that if your four year old beloved son/tyrant wakes you in the middle of the night and keeps you up for some time, you probably aren't with it enought to try and print a 6 colour linocut with a tricky registration. I didn't change this print based on an aesthetic decision. I simply messed up the layout but decided to run with it. I decided I like it this way.

The Matchbook Project Cabinet of Curiosities


I am really pleased to be invited to take part in the The Matchbook Project, especially since the theme this year is Cabinet of Curiosities. This is a group travelling exhibit/artist exchange where all the participating artists make 10 tiny boxes (3" x 2" x 1") and their contents. You can see images of previous works in this project here or follow the #inventoryofmemorymatchbox hashtag on Instagram. Artists may decide to have similar matchbox covers and differing contents, but I decided to make similar contents and different covers.

I returned to the idea of the two-headed turtle, for something which is both an example of natural history and something extraordinary which might fit in your wonderkammer. I carved two matching lino blocks for the turtle from above with the top of its shell and the turtle from below with the bottom of its shell and printed these on Japanese cardstock. Then I printed the shell itself on many different washi papers so I cold collage each section of the shell seperately.

I made the matchboxes themselves from Japanese cardstock in assorted colours, textures and sometimes with inclusions like gold and silver foil or silk fibres. Then I made assorted tiny pillows on which the polycephaly (two-headed turtle) specimen could rest. These were made in red silk or patterned cotton with a Japanese motif or botanical drawings (which fit with the cabinet of curiosity theme).
I collaged each of the boxes with all the bits of prints and proofs I've been saving so long: turtles on assorted washi, insect wings on delicate tissue, crystals on irridescent paper, beetles on washi, bees, radiolarians, fossils, mushrooms, butterflies and tiny vintage tarot cards from a beautiful sheet of paper I bought in Amsterdam many years ago.

I had so much fun making these I think I'll make more. I'm planning to list a mystery box in my shop, so that you can purchase one and have the contents be a surprise!

Chemist Alice Ball, chaulmoogra and the first effective method for treating leprosy

Alice Ball, 11" x 14", linocut by Ele Willoughby, 2018, shows the chemist, branches of the chaulmoogra tree and
how she formed the ethyl ester of chaulmoogric acid (the acid plus alcohol produces the ethyl ester with water)

Leprosy is a disfiguring disease which has afflicted people for millenia. Though her work was stolen and she died tragically young, we now recognize Alice Ball, the young black woman chemist, for her discovery of the first effective treatment for leprosy just over a century ago. Today we know that leprosy (or Hansen's disease) is a long-term infection of bacterium Mycobacterium leprae or Mycobacterium lepromatosis, which can usually be treated with a mix of modern antibiotics. It's likely however that leprosy is as old as human history and descriptions of the symptoms of the disease appear in ancient texts, including Hippocrates (460 BCE) and the Hindu scripture the Atharva Veda from 2,000 BCE. Signs of the disease have been found in skeletal remains from 2,000 BCE. Those infected may not show symptoms for as many as 5 to 20 years, which hindered our understanding of how it was transmitted. Sufferers develop inflammation of the nerves, respiratory track, skin and eyes, as well as skin lesions and can loose the sensation of pain in those areas. This puts them in danger of loosing extremities as repeated injuries, wounds and infection can go unnoticed. People wrongly feared that leprosy was highly contagious, and quarantined the infected in "leper colonies," a practice which persists in some developing countries. There has been significant social stigma associated with the disease, which disproportionately afflicts those living in poverty and and the term "leper" for a person affected with leprosy. Jack London in The Cruise of the Snark described a Hawaiian leper colony as ‘the pit of hell, the most cursed place on Earth’.

In the West, the traditional treatment for leprosy, like syphilis, was mercury, which is of course poisonous. In traditional Indian and Chinese medicine, the oil from the seeds of the chaulmoogra tree (Hydnocarpus wightianus) was used as a treatment. While the oil did indeed combat the disease, it could not be effectively applied. As early as the 1300s, people tried applying chaulmoogra oil topically but it was too sticky. The acrid oil usually lead to vomiting when taken orally. Since it is viscous and can't dissolve in water (or blood), when injected it merely clumped under the skin and the patients were left with rows of oily blisters, with skin resembling bubble wrap. The painful injections were described as "burning like fire through the skin." This partial and flawed, disfiguring treatment for a disfiguring disease was adopted in Western medicine in the 19th century and there were no better options until a 23 year old chemist, Alice Ball was recruited to study chaulmoogra oil in 1915.

Alice Augusta Ball (July 24, 1892 - December 31, 1916) was one of four children in a middle to upper-middle class, black family in Seattle. Her father was a newspaper editor, photographer, and a lawyer, her mother was a photographer and her grandfather was a famous photographer. As such, she grew up around chemicals and the magic of chemistry. The family moved to Honolulu while she was a girl, because they hoped it would help with her grandfather's arthritis, but he died shortly thereafter and they returned to Seattle. Ball studied chemistry at the University of Washington, earning a bachelor's degree in pharmaceutical chemistry and a second degree in pharmacy two years later. She published "Benzoylations in Ether Solution," in the prestigious Journal of the American Chemical Society with her pharmacy instructor, at a time when it was quite an unusual accomplishment for any woman, let alone a woman of colour, to publish in the peer review literature. She was offered various scholarships and opted to return to Hawaii to pursue her master's in chemistry, investigating the active principle of Piper methysticum (a medicinal plant known as kava  or ʻawa). She was both the first woman and the first African American to graduate with a master's degree from the University of Hawai'i. She also became the first Black chemistry professor at the school.

From 1866 to 1942, people diagnosed with leprosy in Hawai'i were arrested and quarantined on the Island of Molokai. Physician Dr. Harry T. Hollmann of the Kalihi Hospital in Hawai'i and acting director of the Kalihi leprosy clinic, was unsatisfied with using chaulmoogra oil in its natural form to treat leprosy patients and wanted to isolate the active ingredients. He recruited the graduate student Ball to help. Within a year, she was able to do what chemists and pharmacologists had been unable to do for centuries. She not only isolated the active ingredients but convert them to a form which could be circulated in the body. By taking the fatty acids present in the oil and exposing them to an alcohol and a catalyst, she produce ethyl esters which are soluble in water, and hence could effectively be injected. My print shows how she formed the ethyl ester of chaulmoogric acid (the acid plus alcohol produces the ethyl ester with water). This breakthrough was so significant, she was offered an instructor position in chemistry at the university. By 1922, her method was widely used to prepare chaulmoogra oil, and patients would might have been subjected to exile, a life of regular painful injections and being trapped in quarantine were instead being effectively cured and discharged!

Tragically, Ball did not live to see the affects of her research. She became ill during her research and returned to Seattle for treatment. She may have been exposed to chlorine gas while demonstrating the use of a gas mask in case of attack (as WWI was raging), but the cause of her death is unknown. Her death certificate was altered and lists tuberculosis as the cause of death, at age 24. She had yet to publish her results when she met her untimely death.

The chemist and president of the University of Hawaii, Arthur L. Dean completed and published her study - but he did not give Ball credit for her work, calling it the "Dean Method"! Dr. Hollmann objected and published an article documenting how the technique should in fact be known as the "Ball Method". The Ball Method relieved the thousands of patients removed from the homes in Hawai'i, forcing their families to hold funerals before their exile. Ball's Method was the preferred treatment for Hansen's disease until the advent of antibiotics in the 1940s. Despite Hollmann's efforts to defend her legacy, Ball's achievements did not receive much recognition until historians learned of and highlighted her work in the 1970s. Almost 90 years after her discovery, the University of Hawai'i finally recognized her work with a plaque on the school's lone chaulmoogra tree in 2000, and the Lieutenant Governor  declared February 29 "Alice Ball Day," now celebrated every four years.

Antoine-Laurent and Marie-Anne Paulze Lavoisier as The Lovers

Antoine et Marie-Anne Paulze Lavoisier, linocut with collaged washi,
2018 by Ele Willoughby
All too often history of science, or the history of science as retold by scientists, neglects to mention women. One of the things I want to do with my series of prints about the history of science is put those excluded back into the story. Sometimes, the missing women are hiding in plain sight! Invited to create a piece inspired by the Lovers tarot card, I thought of French scientists Antoine Lavoisier (26 August 1743 – 8 May 1794) and his wife Marie-Anne Paulze Lavoisier (20 January 1758 – 10 February 1836). Lavoisier is often referred to as the 'father' of modern chemistry, without any reference to his wife. Though many will be familiar with a image of the two, doing chemistry together. Their close friend, famed neo-Classical painter Jacques Louis David painted his Portrait of Anoine-Laurent Lavoisier and his wife in 1788. He also trained Marie-Anne Paulze in drawing and engraving, allowing her to accurately illustrate their experiements. And she most definitely appears in her own drawings and engravings documenting their work.

I hope considering them as a true (and loving team) is a more modern day interpretation of love and their history, as well as a more complete and accurate look at the development of chemistry. The couple, working closely together, modernized and quantified chemistry and the scientific method, recognized and named oxygen and hydrogen, explained the role that oxygen plays in combustion, helped modernize chemical nomenclature and discovered that mass is conserved in chemical reactions. While this has traditionally been described simply as Lavoisier's work modern scholarship points out that Paulze translated all his contemporaries, like Joseph Priestley and Henry Cavendish's manuscripts from English or Latin to French, took notes of all observations, illustrated all experimental set-ups, edited his reports and worked so closely with him we can't easily separate their roles. Perhaps most importantly, her translation of Richard Kirwan's 'Essay on Phlogiston and the Constitution of Acids' with her own footnotes pointing out all the errors in chemistry, convinced her husband to perform their own experiments, which ultimately disproved the popular but incorrect ideas about "phlogiston" (the supposed fire-like element released by substances during combustion) championed by George Stahl, and lead to the discovery of oxygen. Attributing everything to him alone is clearly not the full picture.

While clearly a devoted couple, their history as lovers is a bit complicated, especially looking back with modern eyes. They married in 1771, when Lavoisier was about 28 and Paulze was merely 13! Child marriage is a horrifying prospect and remains a scourge today, but Lavoisier was in fact recruited by Marie-Anne's father Jacques Paulze to rescue her. Both men gained most of their income from the Ferme Générale (the General Farm), a private consortium which paid the Crown for the priviledge of gathering certain taxes. A powerful nobel and member of the consortium, the 50-year-old Count d'Amerval made a formal proposal of marriage to the 13 year old Marie-Anne Paulze, who considered him "a fool, an unfeeling rustic, and an ogre". Wishing to protect her from such a fate, Paulze asked his friend Lavoisier to marry her instead. He agreed, and the couple settled down at the Arsenal in Paris, where he was able to further pursue his growing interest in chemistry and build a state-of-the-art lab. Marie-Anne became interested in these scientific pursuits and soon joined him in the lab. She received formal training in the field from his friends and colleagues Jean Baptiste Michel Bucquet and Philippe Gingembre, and the couple spent most of their time in the lab. Marie-Anne also famously hosted scientific salons with luminaries of the day.

Work Lavoisier undertook to help fund their research, including his role with the Ferme Générale and the tobacco commission, tragically lead to his execution during the French Revolution. She fought to defend his legacy after he was executed. She organized and arranged for the publication of his Mémoires de chimie, including a preface she wrote attacking the revolutionairies she blamed for her husband's death. The book was published by her former lover P.S. du Pont; the idea that the successful marriage and partnership of the Lavoisiers could survive a 10 year affair (1781-1791) with du Pont is quite foreign to modern eyes, but there was little controversy when French nobles of the time took a lover. In fact, when Lavoisier died, her entrusted his wife to his friend du Pont's care. Due to the upheaval of the times, du Pont was unable to repay the money he borrowed from her for his printing venture, and she pursued her financial claim against him and his son for years. The du Ponts moved to the United States, prospered*, repaid their dept and finally published Lavoisier's memoirs of chemistry.

This engraving by Mme Lavoisier shows one of their experiments in human respiration. She is clearly the one recording their data and documenting the experimental set-up on the right.

Mme Lavoisier kept his name for the rest of her life, even during her short-lived second marriage to physicist Sir Benjamin Thomson, Count Rumford. She dumped Rumford as soon as she realized that he did not intend for her to work alongside him in the lab, or respect her Independence as she was accustomed. One of the best physicists of the day who revolutionized our understanding of heat, Thomson fled the U.S., abandoning his first wife after supporting the British side during the American Revolution. He was knighted by George III and made a count after moving to Bavaria, by the Holy Roman Empire. After the death of his estranged wife, he was attracted to the wealthy widow Paulze-Lavoisier, who travelled in the best scientific circles, and saw her wealth as a means of funding his research. Despite a four-year courtship, they soon found they were a bad match. They married in 1805 and separated in 1809.**

I draw on a variety of the aspects of historical tarot cards in my print. I've included the word "L'Amoureux" in French, for this French couple. I chose them, not only as a loving historical scientific couple, but because the card is associated with flames and the element of air. The Lavoisiers studied air and were the ones who really showed that air was not an element (in the modern chemical sense) by isolating various constituent gases like oxygen, and debunking the earlier phlogiston theory. I have specifically shown them with their famous phlogiston experiment apparatus. Further, not only did they recognize the role that oxygen played in combustion, Lavoisier and his friend Pierre-Simon Laplace also recognized that the process of respiration was in fact a slow, controlled combustion - hence the image of the lungs with flames (which is also an allusion to the flaming heart symbol and iconography).

The prints are 7.5" x 12.5" with an image area of 5" x 8.3". Each are printed on Japanese kozo paper, with collaged pink lungs and patterned vest.

As a printmaker, documenting the history of science with relief prints, I love that Marie-Anne Paulze Lavoisier also documented science with relief prints.

* His son Éleuthère, trained by Lavoisier as a chemist, opened a gun-powder manufacturing plant which ultimately became one of the biggest and most successful US companies, DuPont.

**One famous story about the ill-fated Rumford-Lavoisier marriage: annoyed that she had invited many guests without seeking his permission he locked their gate and removed the key. So, she spoke with her guests through the gate and then poured boiling water on his prized flowers. (see 'Women in Chemistry: Their Changing Roles from Alchemical Times to the Mid-Twentieth Century' by Marlene and Geoffrey Rayner-Canham).

Lowering the banner is gallery manager Emma Smith of LandfillDesigns
 This January we say goodbye to our gallery at 906 Queen St W! We had the ceremonial lowering of the Toronto Etsy Street Team Gallery banner. Our year long pop-up gallery adventure has come to an end. It was such a wonderful experience. We loved being able to curate art shows, bring handmade crafts into a gallery environment, have so many of you involved in our shows! Thanks to all the artists, makers, vintage sellers, and amazing volunteers and everyone who came out to our Openings, shows, markets and workshops! Special thanks to our fabulous curators, workshop hosts and volunteers!  Thanks to Graven Feather for welcoming us for the year! 

We’ll have to see what 2018 brings us now...

Looking back at 2017: science, art and life

Wunderkammer, interactive multimedia: linocut, collage, wooden box, electronics, sound files, 2017 by Ele Willoughby
With the new year, like many, I often like to look back. I find sometimes you don't see things accumulate or note acheivements. So, briefly, on a personal front, 2017 was a very interesting year. It was challenging, but over all, I'm quite proud. On one hand it's funny to start off talking about the acheivement of being in the running for a job I didn't get, but astronaut is no ordinary job. I was proud that I even had the guts to submit my application in the summer of 2016 for the Canadian Space Agency's job search. Each step of the year-long search, as I continued to advance I was a strange mixture of astonished yet confident that after all, it was something I could learn to do if selected. So I was very proud to be  one of the top 72 people selected from 3772 initial applicants, who were invited to the Astronaut Recruitment Assessment Centre! It was a unique experience; 3 and half days of gruelling mental, psychological and physical assessment, along with a very impressive and fascinating cohort of fellow applicants (only a third of whom were women). I've had so many questions and comments from people since this experience that I didn't expect. People I just met told me they were proud. Parents told me that they followed my progress with their kids, or asked me advice about how to encourage the next generation of potential astronauts. I wouldn't have imagined that even making it that far in their job search could impact people, but I'm humbled that it did and thank you all for your kindness, encouragement and support.

Another new experience this year was running an art gallery! I'm so glad that Emma talked me into taking on the Toronto Etsy Street Team Gallery, because truth is, I think I would have shied away from the financial risk. But it was a great experience and I'm proud of what we pulled off. I curated my first show, Wunderkammer, with a wonderful collection - a cabinet of curiosity in fact, of science art from some favourite and new-to-me artists. I went on to curate and organize shows about Canada, help foster Rebecca Vaughan curate and participate in Love Your Body, curate and participate in a Mesozoic themed the Dinovember show. I was also really pleased to take part in Tosca Terran's UnNatural History show at the gallery, where I showed my entire unnatural print collection.

2017 also some some great collaborations. WWEST's Phylo Women in STEM trading cards came out this spring. Definitely my favourite commission of 2016, was making and submitting five of my portraits of women. I have previously submitted some art for UBC's Dave Ng's earlier project to use trading cards as a natural historian's version of Pokemon. This latest set brings attention to women in science and technology, throughout history, and the hurdles facing women and under-represented groups. He told me he had seen my blog post about the death of physicist, material scientist and archeometry pioneer Ursula Franklin and it encouraged him to include her, as a great scientist, role model and Canadian. As you can see (above), I've also illustrated marine geologist Marie Tharp, physicist Lise Meitner, seismologist Inge Lehmann and proto-computer scientist Ada Lovelace. The sets are available from Phylo and you are even free to download and print your own! 

Because life is odd, the day after I learned that I did not advance to the top 32 astronaut candidates, Anthropologie approached me about collaborating on tee shirts. They loved my 'terms of venery' series of group nouns for animals.  They licensed two of my existing prints, 'An Ostentation of Peacocks' and 'A Kaleidoscope of Butterflies' and commissioned a third work. They wanted my portrait of my beloved, late, great Minouette the cat, but wanted it to fit in the venery series. While a group of cats is often known as a clowder, I remembered that it can also be called a glaring, and I thought that was a perfect combination for her fierce "Stop carving lino and feed me now!" look. I was very excited to work with one of my favourite clothing stores and it was a lovely experience to work with them. I was gratified that they wanted artwork that I had made simply because I wanted to.

 2017 also saw my home, studio and peculiar combination of jobs and interests as the subject of this Toronto Star article. I participated in another Bees (& the Birds) show. I did all the Toronto Etsy Street Team craft shows: the Midsummer Market, Etsy Made in Canada (where I enjoyed playing second fiddle for the first time) and the Christmas Maket. I sold at the One of a Kind Christmas show once again. I had artwork selected for the Leftovers VI Silent Auction, in Boise, Idaho, and 'Life as we knew it' and 'LUNAR' art shows at Art.Science.Gallery in Austin, Texas.

On the home front, our son turned four at the end of November, which means that he was able to start kindergarten in September. This is a big shift and I'm still getting used to it. He's now at school 6 hours a day, which frees me up to have much more freedom and control of my time and schedule and he loves it and is flourishing!

I love most of all that this list is very mixed: art, science, family life, and I'm keeping people guessing. When I was young I thought I had to choose, but I think in 2017 I did a good job of not choosing and being as much of a Renaissance woman as I can. I'm rather enjoying not having to define myself one way. This year once again promises new things and I'm looking forward to seeing what it brings.

Dinovember and One of a Kind and Scienterrific and the TEST Christmas Market

Well November is always a busy time of year! This year I also curated and showed in DINOVEMBER, November 4 to 14, a dinosaur themed art show at the Toronto Etsy Street Team Gallery! We had a number of fun and beautiful works including painting, printmaking and scupture; jewellery, housewares, cards and toys. Peggy Muddles of the vexed muddler outdid herself, with a large ceramic dinosaur heart (with anatomy inferred from modern-day bird and reptile hearts) with Cretaceous flora and fauna (palms, grains, mosses, and butterflies) which used a proximity sensor to trigger the playing of a sound file (a composition of electronic music inspired by the time period).

The One of a Kind Show (November 23 to December 3) while always a bit of a marathon for handmakers selling their work, felt like it went faster than in previous years. I debuted my new booth, built by my husband. It's always great to see the "travelling circus" of artists and artisans again. Thank you very much to everyone who came out, helped me, said hello or purchased art!

The next weekend, Peggy Muddles hosted a Scienterrific #sciart pop-up market at the Toronto Etsy Street Team Gallery. Cause she's the best, she let me set-up and abandon my art work there and she sold it on my behalf. I was busy celebrating my son's 4th birthday! His actual birthday was during the One of a Kind, but we opted for the sane plan of delaying the party until afterwards. As one maker friend put it, "Throwing a birthday party during OOAK is like throwing a wedding while at the Olympics!"

Then last weekend was the always-fun Toronto Etsy Street Team Christmas Market at St Stephens-in-the-Fields church in Kensington Market. We had Krampus and Santa visit - as well as an unscheduled visit from the Toronto Fire Department, conveniently from the fire hall across the street due to an alarm! Thank you very much to everyone who came out. I thoroughly enjoyed myself.... but am thankful to be done with all shows and exhibits for 2017. Now I'm going to make some cookies and relax.
