Tucked away on a side street near Central Park, the New York Academy of Medicine Library is one of the most significant historical medical libraries in the world. Open to the public by appointment since the 19th century, its collection includes 550,000 volumes on subjects ranging from ancient brain surgery to women's medical colleges to George Washington's dentures. A few weeks ago, Mental Floss visited to check out some of their most fascinating items connected to the study of anatomy. Whether it was urine wheels or early anatomy pop-up books, we weren't disappointed.

1. FASCICULUS MEDICINAE (1509)

The Fasciculus Medicinae is a compilation of Greek and Arabic texts first printed in Venice in 1491. While it covers a variety of topics including anatomy and gynecology, the book begins with the discipline considered most important for diagnosing all medical issues at the time: uroscopy (the study of urine). The NYAM Library's curator, Anne Garner, showed us the book's urine wheel, which once had the various flasks of urine colored in to help aid physicians in their diagnosis. Each position of the wheel corresponded to one of the four humors, whether it was phlegmatic, choleric, sanguine, or melancholic. The image on the left, Garner explains, "shows the exciting moment where a servant boy brings his flasks to be analyzed by a professor." Other notable images in the book include one historians like to call "Zodiac Man," showing how the parts of the body were governed by the planets, and "Wound Man," who has been struck by every conceivable weapon, and is accompanied by a text showing how to treat each type of injury. Last but not least, the book includes what's believed to be the first printed image of a dissection.

2. ANDREAS VESALIUS, DE HUMANI CORPORIS FABRICA (1543)

Andreas Vesalius, born 1514, was one of the most important anatomists who ever lived. Thanks to him, we moved past an understanding of the human body based primarily on the dissection of animals and toward training that involved the direct dissection of human corpses. The Fabrica was written by Vesalius and published when he was a 28-year-old professor at the University of Padua. Its detailed woodcuts, the most accurate anatomical illustrations up to that point, influenced the depiction of anatomy for centuries to come. "After this book, anatomy divided up into pre-Vesalian and post-Vesalian," Garner says. You can see Vesalius himself in the book's frontispiece (he's the one pointing to the corpse and looking at the viewer). "Vesalius is trying to make a point that he himself is doing the dissection, he believes that to understand the body you have to open it up and look at it," Garner explains.

3. THOMAS GEMINUS, COMPENDIOSA (1559)

There was no copyright in the 16th century, and Vesalius's works were re-used by a variety of people for centuries. The first was in Flemish printer and engraver Thomas Geminus’s Compendiosa, which borrowed from several of Vesalius's works. The first edition was published in London just two years after the Fabrica. Alongside a beautiful dedication page made for Elizabeth I and inlaid with real gemstones, the book also includes an example of a "flap anatomy" or a fugitive leaf, which was printed separately with parts that could be cut out and attached to show the various layers of the human body, all the way down to the intestines. As usual for the time, the female is depicted as pregnant, and she holds a mirror that says "know thyself" in Latin.

4. WILLIAM COWPER, THE ANATOMY OF HUMANE BODIES (1698)

After Vesalius, there was little new in anatomy texts until the Dutch anatomist Govard Bidloo published his Anatomia humani corporis in 1685. The work was expensive and not much of a financial success, so Bidloo sold excess plates to the English anatomist William Cowper, who published the plates with an English text without crediting Bidloo (a number of angry exchanges between the two men followed). The copperplate engravings were drawn by Gérard de Lairesse, who Garner notes was "incredibly talented." But while the engravings are beautiful, they're not always anatomically correct, perhaps because the relationship between de Lairesse and Bidloo was fraught (Bidloo was generally a bit difficult). The skeleton shown above is depicted holding an hourglass, by then a classic of death iconography.

5. 17TH-CENTURY IVORY MANIKINS

These exquisite figures are a bit of a mystery: It was originally thought that they were used in doctors’ offices to educate pregnant women about what was happening to their bodies, but because of their lack of detail, scholars now think they were more likely expensive collector's items displayed in cabinets of curiosity by wealthy male physicians. The arms of the manikins (the term for anatomical figures like this) lift up, allowing the viewer to take apart their removable hearts, intestines, and stomachs; the female figure also has a little baby inside her uterus. There are only about 100 of these left in the world, mostly made in Germany, and NYAM has seven.

6. BERNHARD SIEGFRIED ALBINUS, TABULAE SCELETI (1747)

One of the best-known anatomists of the 18th century, the Dutch anatomist Bernhard Siegfried Albinus went to medical school at age 12 and had a tenured position at the University of Leiden by the time he was 24. The Tabulae Sceleti was his signature work. The artist who worked on the text, Jan Wandelaar, had studied with Gérard de Lairesse, the artist who worked with Bidloo. Wandelaar and Albinus developed what Garner says was a bizarre method of suspending cadavers from the ceiling in the winter and comparing them to a (very cold and naked) living person lying on the floor in the same pose. Albinus also continued the dreamy, baroque funerary landscape of his predecessors, and his anatomy is "very, very accurate," according to Garner.

The atlas also features an appearance by Clara, a celebrity rhinoceros, who was posed with one of the skeletons. "When Albinus is asked why [he included a rhinoceros], he says, 'Oh, Clara is just another natural wonder of the world, she's this amazing creation,' but really we think Clara is there to sell more atlases because she was so popular," Garner says.

7. FERDINAND HEBRA, ATLAS DER HAUTKRANKHEITEN (1856–1876)

By the mid-19th century, dermatology had started to emerge as its own discipline, and the Vienna-based Ferdinand Hebra was a leading light in the field. He began publishing this dermatological atlas in 1856 (it appeared in 10 installments), featuring chromolithographs that showed different stages of skin diseases and other dermatological irregularities.

"While some of the images are very disturbing, they also tend to adhere to Victorian portrait conventions, with very ornate hair, and [subjects] looking off in the distance," Garner says. But one of the most famous images from the book has nothing to do with disease—it's a depiction of Georg Constantin, a well-known Albanian circus performer in his day, who was covered in 388 tattoos of animals, flowers, and other symbols. He travelled throughout Europe and North America, and was known as "Prince Constantine" during a spell with Barnum's Circus. (The image is also available from NYAM as a coloring sheet.)

8. KOICHI SHIBATA, OBSTETRICAL POCKET PHANTOM (1895)

Obstetrical phantoms, often made of cloth, wood, or leather, were used to teach medical students about childbirth. This "pocket phantom" was originally published in Germany, and Garner explains that because it was made out of paper, it was much cheaper for medical students. The accompanying text, translated in Philadelphia, tells how to arrange the phantom and describes the potential difficulties of various positions.

9. ROBERT L. DICKINSON AND ABRAM BELSKIE, BIRTH ATLAS (1940)

Robert Dickinson was a Brooklyn gynecologist, early birth control advocate, and active member of NYAM. His Birth Atlas is illustrated with incredibly lifelike terracotta models created by New Jersey sculptor Abram Belskie. The models were exhibited at the 1939 New York World's Fair, where they became incredibly popular, drawing around 700,000 people according to Garner. His depictions "are very beautiful and serene, and a totally different way of showing fetal development than anything that had come before," Garner notes.

10. RALPH H. SEGAL, THE BODYSCOPE (1948)

The Bodyscope

This midcentury cardboard anatomy guide contains male and female figures as well as rotating wheels, called volvelles, that can be turned to display details on different parts of the body as well as accompanying explanatory text. The Bodyscope is also decorated with images of notable medical men—and "wise" sayings about God's influence on the body.

Eliza Leslie: The Most Influential Cookbook Writer of the 19th Century

If it wasn't for Eliza Leslie, American recipes might look very different. Leslie wrote the most popular cookbook of the 19th century, published a recipe widely credited as being the first for chocolate cake in the United States, and authored fiction for both adults and children. Her nine cookbooks—as well as her domestic management and etiquette guides—made a significant mark in American history and society, despite the fact that she never ran a kitchen of her own.

Early Dreams

Born in Philadelphia on November 15, 1787, to Robert and Lydia Leslie, Eliza was an intelligent child and a voracious reader. Her dream of becoming a writer was nurtured by her father, a prosperous watchmaker, inventor, and intellectual who was friends with Benjamin Franklin and Thomas Jefferson. She once wrote that "the dream of my childhood [was] one day seeing my name in print."

Sadly, her father’s business failed around the turn of the 19th century and he died in 1803. The family took in boarders to make ends meet, and as the oldest of five, Leslie helped her mother in the kitchen. To gain culinary experience, she attended Mrs. Goodfellow’s Cooking School in Philadelphia, the first school of its kind in the United States. Urged by her brother Thomas—and after fielding numerous requests for recipes from friends and family—she compiled her first book, Seventy-Five Receipts for Pastry, Cakes, and Sweetmeats, in 1828. Notably, the book included the term cup cake, referring to Leslie's employment of a teacup as a measuring tool ("two large tea-cups full of molasses")—possibly the first-ever mention of a cup cake in print.

Seventy-Five Receipts was a hit, and was reprinted numerous times. Encouraged by this success—and by her publisher, Munroe & Francis—Leslie moved on to her true desire: writing fiction. She penned short stories and storybooks for young readers as well as adult fiction and won several awards for her efforts. One of her prize-winning short stories, the humorous "Mrs. Washington Potts," appeared in Godey’s Lady’s Book, the popular 19th century magazine for which she also served as assistant editor. Leslie also contributed to Graham’s Magazine, the Saturday Gazette, and The Saturday Evening Post. At least one critic called her tales "perfect daguerreotypes of real life."

As much as Leslie loved writing fiction, however, it didn't always pay the bills. She wrote a second cookbook, Domestic French Cookery, in 1832, and achieved the pinnacle of her success in 1837 with Directions for Cookery. That work became the most beloved cookbook of the 1800s; it sold at least 150,000 copies and was republished 60 times by 1870. She offered pointers on procuring the best ingredients ("catfish that have been caught near the middle of the river are much nicer than those that are taken near the shore where they have access to impure food") and infused the book with wit. In a section discouraging the use of cold meat in soups, she wrote, "It is not true that French cooks have the art of producing excellent soups from cold scraps. There is much bad soup to be found in France, at inferior houses; but good French cooks are not, as is generally supposed, really in the practice of concocting any dishes out of the refuse of the table."

In The Taste of America, noted modern food historians John and Karen Hess called Directions for Cookery “one of the two best American cookbooks ever written," citing the book's precise directions, engaging tips, straightforward commentary, and diverse recipes—such as catfish soup and election cake—as the keys to its excellence.

Leslie is also credited with publishing America’s first printed recipe for chocolate cake, in her 1846 Lady’s Receipt Book. While chocolate had been used in baking in Europe as far back as the 1600s, Leslie’s recipe was probably obtained from a professional chef or pastry cook in Philadelphia. The recipe, which featured grated chocolate and a whole grated nutmeg, is quite different from most of today's chocolate cakes, with its strong overtones of spice and earthy, rather than sweet, flavors. (You can find the full recipe below.)

Later in life, while continuing to write cookbooks, Leslie edited The Gift: A Christmas and New Year’s Present, which included early publications by Edgar Allan Poe. She also edited her own magazine of literature and fashion, Miss Leslie’s Magazine. She wrote only one novel, 1848's Amelia; Or a Young Lady’s Vicissitudes, but once said that if she was to start her literary career over, she would have only written novels.

A Uniquely American Voice

Historians have argued that Leslie was successful because she crafted recipes to appeal to the young country’s desire for upward mobility as well as a uniquely American identity. At the time she began writing, women primarily used British cookbooks; Leslie appealed to them with a distinctly American work. (She noted in the preface to Seventy-Five Receipts, "There is frequently much difficulty in following directions in English and French Cookery Books, not only from their want of explicitness, but from the difference in the fuel, fire-places, and cooking utensils. ... The receipts in this little book are, in every sense of the word, American.")

Leslie included regional American dishes in her books, promoted the use of quality ingredients, and was the first to (sometimes) organize recipes by including ingredients at the beginning of each recipe instead of using a narrative form, setting the tone for modern recipe writing. Her books were considered a treasure trove of knowledge for young pioneer women who, frequently separated from their families for the first time, often relied on Leslie's works for guidance.

Unmarried herself, Leslie never managed her own kitchen, and often had others testing recipes for her. She maintained strong ties with her erudite, sophisticated family, and lived for a time with her brother Thomas while he was attending West Point. Another brother, Charles Leslie, was a well-regarded painter in England; her sister Anna was also an artist, and sister Patty was married to a publisher who produced some of Leslie’s work. As she got older, Leslie lived for years in the United States Hotel in Philadelphia, where she was something of a celebrity for her wit and strong opinions.

Leslie died on January 1, 1858. Many of her recipes are still used today, but it's likely she’d be most pleased to know that many of her short stories are available online. Modern readers can appreciate the totality of her work: the fiction writing that was her passion, though for which she was lesser known, and her culinary writing, which guided generations.

Eliza Leslie's Recipe for Chocolate Cake

From The Lady's Receipt Book:

CHOCOLATE CAKE.—Scrape down three ounces of the best and purest chocolate, or prepared cocoa. Cut up, into a deep pan, three-quarters of a pound of fresh butter; add to it a pound of powdered loaf-sugar; and stir the butter and sugar together till very light and white. Have ready 14 ounces (two ounces less than a pound) of sifted flour; a powdered nutmeg; and a tea-spoonful of powdered cinnamon—mixed together. Beat the whites of ten eggs till they stand alone; then the yolks till they are very thick and smooth. Then mix the yolks and whites gradually together, beating very hard when they are all mixed. Add the eggs, by degrees, to the beaten butter and sugar, in turn with the flour and the scraped chocolate,—a little at a time of each; also the spice. Stir the whole very hard. Put the mixture into a buttered tin pan with straight sides, and bake it at least four hours. If nothing is to be baked afterwards, let it remain in till the oven becomes cool. When cold, ice it.

11 Facts About Johann Sebastian Bach

Johann Sebastian Bach is everywhere. Weddings? Bach. Haunted houses? Bach. Church? Bach. Shredding electric guitar solos? Look, it’s Bach! The Baroque composer produced more than 1100 works, from liturgical organ pieces to secular cantatas for orchestra, and his ideas about musical form and harmony continue to influence generations of music-makers. Here are 11 things you might not know about the man behind the music.

1. There's some disagreement about when he was actually born.

Some people celebrate Bach’s birthday on March 21. Other people light the candles on March 31. The correct date depends on whom you ask. Bach was born in Thuringia in 1685, when the German state was still observing the Julian calendar. Today, we use the Gregorian calendar, which shifted the dates by 11 days. And while most biographies opt for the March 31 date, Bach scholar Christopher Wolff firmly roots for Team 21. “True, his life was actually 11 days longer because Protestant Germany adopted the Gregorian calendar in 1700,” he told Classical MPR, “but with the legal stipulation that all dates prior to Dec. 31, 1699, remain valid.”

2. He was at the center of a musical dynasty.

Bach’s great-grandfather was a piper. His grandfather was a court musician. His father was a violinist, organist, court trumpeter, and kettledrum player. At least two of his uncles were composers. He had five brothers—all named Johann—and the three who lived to adulthood became musicians. J.S. Bach also had 20 children, and, of those who lived past childhood, at least five became professional composers. According to the Nekrolog, an obituary written by Bach’s son Carl Philipp Emanuel Bach, "[S]tarting with Veit Bach, the founding father of this family, all his descendants, down to the seventh generation, have dedicated themselves to the profession of music, with only a few exceptions."

3. He took a musical pilgrimage that puts every road trip to Woodstock to shame.

In 1705, 20-year-old Bach walked 280 miles—that's right, walked—from the city of Arnstadt to Lübeck in northern Germany to hear a concert by the influential organist and composer Dieterich Buxtehude. He stuck around for four months to study with the musician [PDF]. Bach hoped to succeed Buxtehude as the organist of Lübeck's St. Mary's Church, but marriage to one of Buxtehude's daughters was a prerequisite to taking over the job. Bach declined, and walked back home.

4. He brawled with his students.

One of Bach’s first jobs was as a church organist in Arnstadt. When he signed up for the role, nobody told him he also had to teach a student choir and orchestra, a responsibility Bach hated. Not one to mince words, Bach one day lost patience with a error-prone bassoonist, Johann Geyersbach, and called him a zippelfagottist—that is, a “nanny-goat bassoonist.” Those were fighting words. Days later, Geyersbach attacked Bach with a walking stick. Bach pulled a dagger. The rumble escalated into a full-blown scrum that required the two be pulled apart.

5. He spent 30 days in jail for quitting his job.

When Bach took a job in 1708 as a chamber musician in the court of the Duke of Saxe-Weimar, he once again assumed a slew of responsibilities that he never signed up for. This time, he took it in stride, believing his hard work would lead to his promotion to kapellmeister (music director). But after five years, the top job was handed to the former kapellmeister’s son. Furious, Bach resigned and joined a rival court. As retribution, the duke jailed him for four weeks. Bach spent his time in the slammer writing preludes for organ.

6. The Brandenburg Concertos were a failed job application.

Around 1721, Bach was the head of court music for Prince Leopold of Anhalt-Köthen. Unfortunately, the composer reportedly didn’t get along with the prince’s new wife, and he started looking for a new gig. (Notice a pattern?) Bach polished some manuscripts that had been sitting around and mailed them to a potential employer, Christian Ludwig, the Margrave of Brandenburg. That package, which included the Brandenburg Concertos—now considered some of the most important orchestral compositions of the Baroque era—failed to get Bach the job [PDF].

7. He wrote an amazing coffee jingle.

Bach apparently loved coffee enough to write a song about it: "Schweigt stille, plaudert nicht" ("Be still, stop chattering"). Performed in 1735 at Zimmerman’s coffee house in Leipzig, the song is about a coffee-obsessed woman whose father wants her to stop drinking the caffeinated stuff. She rebels and sings this stanza:

Ah! How sweet coffee tastes
More delicious than a thousand kisses
Milder than muscatel wine.
Coffee, I have to have coffee,
And, if someone wants to pamper me,
Ah, then bring me coffee as a gift!

8. If Bach challenged you to a keyboard duel, you were guaranteed to be embarrassed.

In 1717, Louis Marchand, a harpsichordist from France, was invited to play for Augustus, Elector of Saxony, and performed so well that he was offered a position playing for the court. This annoyed the court’s concertmaster, who found Marchand arrogant and insufferable. To scare the French harpsichordist away, the concertmaster hatched a plan with his friend, J.S. Bach: a keyboard duel. Bach and Marchand would improvise over a number of different styles, and the winner would take home 500 talers. But when Marchand learned just how talented Bach was, he hightailed it out of town.

9. Some of his music may have been composed to help with insomnia.

Some people are ashamed to admit that classical music, especially the Baroque style, makes them sleepy. Be ashamed no more! According to Bach’s earliest biographer, the Goldberg Variations were composed to help Count Hermann Karl von Keyserling overcome insomnia. (This story, to be fair, is disputed.) Whatever the truth, it hasn’t stopped the Andersson Dance troupe from presenting a fantastic Goldberg-based tour of performances called “Ternary Patterns for Insomnia.” Sleep researchers have also suggested studying the tunes’ effects on sleeplessness [PDF].

10. A botched eye surgery blinded him.

When Bach was 65, he had eye surgery. The “couching” procedure, which was performed by a traveling surgeon named John Taylor, involved shoving the cataract deep into the eye with a blunt instrument. Post-op, Taylor gave the composer eye drops that contained pigeon blood, mercury, and pulverized sugar. It didn’t work. Bach went blind and died shortly after. Meanwhile, Taylor moved on to botch more musical surgeries. He would perform the same procedure on the composer George Frideric Handel, who also went blind.

11. Nobody is 100 percent confident that Bach is buried in his grave.

In 1894, the pastor of St. John’s Church in Leipzig wanted to move the composer’s body out of the church graveyard to a more dignified setting. There was one small problem: Bach had been buried in an unmarked grave, as was common for regular folks at the time. According to craniologist Wilhelm His, a dig crew tried its best to find the composer but instead found “heaps of bones, some in many layers lying on top of each other, some mixed in with the remains of coffins, others already smashed by the hacking of the diggers.” The team later claimed to find Bach’s box, but there’s doubt they found the right (de)composer. Today, Bach supposedly resides in Leipzig’s St. Thomas Church.
