Women in Medicine: 6 Pioneering Activists

Original image

It was once a great struggle for a woman to even be considered for a medical education in the United States—or anywhere, for that matter. Only the strongest, most dedicated women managed to achieve a degree, and they deserve to be remembered for their efforts. These early pioneers in the medical field opened the doors for the many woman doctors who followed.

1. Ann Preston

Dr. Ann Preston (pictured above) was a teacher who worked to educate women about their own bodies. She always continued her own education, too, and worked as an apprentice to a doctor before applying to four different medical schools in Philadelphia, and was rejected—just like all the other female applicants. When the Female Medical College of Pennsylvania was founded in 1850, Preston enrolled in its first class. She graduated a year and a half later, then became a professor at the school. Meanwhile, she founded the Woman’s Hospital of Philadelphia, and changed the name of the school to the Women’s Medical College of Pennsylvania. In 1866, she became Dean of the college, the first woman to hold the title. Preston then fought for the right of her students to attend clinics at various local hospitals just like male medical students. It was not an easy battle. In 1868, Preston’s students were allowed to observe a clinic at Blockley Hospital.

When the first women arrived, however, they were met by an angry demonstration. The male medical students shouted insults and threw paper, tinfoil and tobacco quids at the women. The female students remained composed and attended the clinic, but on their way out they were pelted with rocks.

It would not be the last time such behavior greeted the doctors-in-training. But Preston kept up her support of her medical students even as her own health failed. She died in 1872 and bequeathed her assets to the the Women’s Medical College of Pennsylvania to fund scholarships.

2. Mary Edwards Walker

Dr. Mary Edwards Walker was the only woman in her medical school class in 1855. Her medical practice floundered because few people trusted a woman doctor. Walker volunteered her service to the Union Army, but was not allowed to enlist, so she served as a volunteer. She was not allowed to serve as a doctor, either, so she served as a nurse—at first. Walker ministered to the wounded at the First Battle of Bull Run and worked her way into the position of a field surgeon's assistant. She was awarded an army commission 1863, but was still technically designated as a civilian worker. Walker was taken by the Confederacy as a prisoner of war for several months in 1864 and was accused of being a spy. She continued to serve until the end of the war. In 1865 Walker became the only woman ever to receive the Medal of Honor, for her efforts at the First Battle of Bull Run. After the war, she campaigned for women's rights, temperance, and even ran for political office—before women even had the right to vote.

3. Rebecca Lee Crumpler

Dr. Rebecca Lee Crumpler was the first black woman to earn a medical degree in the U.S. She was born in Delaware in 1833 and grew up in Pennsylvania. As an adult, Lee worked as a nurse in Boston by on-the-job training, as there were no nursing schools at the time. Her supervisors were impressed with her work and suggested she try medical school. Despite the references, it took eight years for a college to admit her. In 1860, she entered the New England Female Medical College and graduated in 1864. She then married Arthur Crumpler. After the Civil War, Dr. Crumpler moved to Richmond, Virginia, where she could serve the medical needs of recently freed slaves. She later wrote that Richmond was

“…a proper field for real missionary work, and one that would present ample opportunities to become acquainted with the diseases of women and children. During my stay there nearly every hour was improved in that sphere of labor. The last quarter of the year 1866, I was enabled . . . to have access each day to a very large number of the indigent, and others of different classes, in a population of over 30,000 colored."

Crumpler returned to Massachusetts four years later and opened her own practice. She wrote Book of Medical Discourses, which includes her biography, but mostly focuses on how women can meet the medical needs of their families. It was published in 1883. In spite of her place in history, there are no existing photographs of Dr. Rebecca Lee Crumpler.

4. Mary Putnam Jacobi

In 1873, Harvard professor Edward Clarke published a book entitled Sex in Education; or, A Fair Chance For Girls. Despite a promising title, what he meant by “a fair chance” was to discourage higher education for women because,

"There have been instances, and I have seen such, of females... graduated from school or college excellent scholars, but with undeveloped ovaries. Later they married, and were sterile."

Clarke’s rationale was that a woman couldn’t menstruate and think at the same time, and trying to do so was dangerous. Therefore, keeping women out of colleges and universities was for their own good. Few took exception to Clarke’s opinions, but one who did was Mary Putnam Jacobi, a doctor, scientist, and extraordinary woman of her time. Jacobi earned a medical degree at Woman’s Medical College of Pennsylvania in 1864 (where she received her M.D. at age 22), then went on to study at France’s famous École de Médecine, where she was the first woman ever admitted. Dr. Jacobi objected to Clarke’s views, but knew that her opinion wouldn’t matter a bit. Instead, she used research. Jacobi gathered empirical data on real women, and presented her findings without emotion or personal opinion.

“There is nothing in the nature of menstruation to imply the necessity, or even the desirability, of rest.”

Jacobi’s work won awards and helped to break down barriers in women’s education.

5. Georgia E.L. Patton

Dr. Georgia E.L. Patton was the first black woman to be licensed as a doctor in the state of Tennessee. She was born into slavery in 1864, and became the only member of her family to graduate from high school. Her brother and sisters worked to help her pay for college, then she continued to the Meharry Medical Department of Central Tennessee College, where she earned her medical degree in 1893. Patton left immediately for Liberia as a medical missionary, where she served for two years despite her church’s refusal to fund the trip. Patton contracted tuberculosis on what she thought would be a temporary trip back to the U.S., and never fully regained her health. Still, she set up a private practice in Memphis, where she was the only black female doctor. Patton practiced there for a few years, married, and had two children who died in infancy. Patton was only 36 years old when she died in 1900.

6. Sara Josephine Baker

Dr. Sara Josephine Baker got her M.D. from the Woman’s Medical College of the New York Infirmary in 1898. Her private practice made so little money that she went to work for the City of New York as a medical inspector. Working with the poorest immigrants in the Hell’s Kitchen area, Baker became dedicated to preventative care. She knew that educating people on basic infant care, nutrition, and sanitation could save many lives and health care resources in the long run. Baker was appointed assistant commissioner of health for the city in 1907. She began programs that to provide New York residents with prenatal care, childcare classes, infant formula, baby clothes, vaccines, and milk. She took babies out of orphanages and put them into foster care, where they would receive individual attention, leading to a lower death rate. She was also instrumental in catching Mary Mallon, known a Typhoid Mary, twice. Dr. Baker became famous for getting results in public health, and in her later years was in demand to teach her methods in other states and in cities around the world.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning
Original image

Jacques Mattheij made a small, but awesome, mistake. He went on eBay one evening and bid on a bunch of bulk LEGO brick auctions, then went to sleep. Upon waking, he discovered that he was the high bidder on many, and was now the proud owner of two tons of LEGO bricks. (This is about 4400 pounds.) He wrote, "[L]esson 1: if you win almost all bids you are bidding too high."

Mattheij had noticed that bulk, unsorted bricks sell for something like €10/kilogram, whereas sets are roughly €40/kg and rare parts go for up to €100/kg. Much of the value of the bricks is in their sorting. If he could reduce the entropy of these bins of unsorted bricks, he could make a tidy profit. While many people do this work by hand, the problem is enormous—just the kind of challenge for a computer. Mattheij writes:

There are 38000+ shapes and there are 100+ possible shades of color (you can roughly tell how old someone is by asking them what lego colors they remember from their youth).

In the following months, Mattheij built a proof-of-concept sorting system using, of course, LEGO. He broke the problem down into a series of sub-problems (including "feeding LEGO reliably from a hopper is surprisingly hard," one of those facts of nature that will stymie even the best system design). After tinkering with the prototype at length, he expanded the system to a surprisingly complex system of conveyer belts (powered by a home treadmill), various pieces of cabinetry, and "copious quantities of crazy glue."

Here's a video showing the current system running at low speed:

The key part of the system was running the bricks past a camera paired with a computer running a neural net-based image classifier. That allows the computer (when sufficiently trained on brick images) to recognize bricks and thus categorize them by color, shape, or other parameters. Remember that as bricks pass by, they can be in any orientation, can be dirty, can even be stuck to other pieces. So having a flexible software system is key to recognizing—in a fraction of a second—what a given brick is, in order to sort it out. When a match is found, a jet of compressed air pops the piece off the conveyer belt and into a waiting bin.

After much experimentation, Mattheij rewrote the software (several times in fact) to accomplish a variety of basic tasks. At its core, the system takes images from a webcam and feeds them to a neural network to do the classification. Of course, the neural net needs to be "trained" by showing it lots of images, and telling it what those images represent. Mattheij's breakthrough was allowing the machine to effectively train itself, with guidance: Running pieces through allows the system to take its own photos, make a guess, and build on that guess. As long as Mattheij corrects the incorrect guesses, he ends up with a decent (and self-reinforcing) corpus of training data. As the machine continues running, it can rack up more training, allowing it to recognize a broad variety of pieces on the fly.

Here's another video, focusing on how the pieces move on conveyer belts (running at slow speed so puny humans can follow). You can also see the air jets in action:

In an email interview, Mattheij told Mental Floss that the system currently sorts LEGO bricks into more than 50 categories. It can also be run in a color-sorting mode to bin the parts across 12 color groups. (Thus at present you'd likely do a two-pass sort on the bricks: once for shape, then a separate pass for color.) He continues to refine the system, with a focus on making its recognition abilities faster. At some point down the line, he plans to make the software portion open source. You're on your own as far as building conveyer belts, bins, and so forth.

Check out Mattheij's writeup in two parts for more information. It starts with an overview of the story, followed up with a deep dive on the software. He's also tweeting about the project (among other things). And if you look around a bit, you'll find bulk LEGO brick auctions online—it's definitely a thing!

Nintendo Will Release an $80 Mini SNES in September

Retro gamers rejoice: Nintendo just announced that it will be launching a revamped version of its beloved Super Nintendo Classic console, which will allow kids and grown-ups alike to play classic 16-bit games in high-definition.

The new SNES Classic Edition, a miniature version of the original console, comes with an HDMI cable to make it compatible with modern televisions. It also comes pre-loaded with a roster of 21 games, including Super Mario Kart, The Legend of Zelda: A Link to the Past, Donkey Kong Country, and Star Fox 2, an unreleased sequel to the 1993 original.

“While many people from around the world consider the Super NES to be one of the greatest video game systems ever made, many of our younger fans never had a chance to play it,” Doug Bowser, Nintendo's senior vice president of sales and marketing, said in a statement. “With the Super NES Classic Edition, new fans will be introduced to some of the best Nintendo games of all time, while longtime fans can relive some of their favorite retro classics with family and friends.”

The SNES Classic Edition will go on sale on September 29 and retail for $79.99. Nintendo reportedly only plans to manufacture the console “until the end of calendar year 2017,” which means that the competition to get your hands on one will likely be stiff, as anyone who tried to purchase an NES Classic last year will well remember.

In November 2016, Nintendo released a miniature version of its original NES system, which sold out pretty much instantly. After selling 2.3 million units, Nintendo discontinued the NES Classic in April. In a statement to Polygon, the company has pledged to “produce significantly more units of Super NES Classic Edition than we did of NES Classic Edition.”

Nintendo has not yet released information about where gamers will be able to buy the new console, but you may want to start planning to get in line soon.
