Rectangular Lattice

Thousands of premature infants were saved from certain death by being part of a Coney Island entertainment sideshow.

At the time premature babies were considered genetically inferior, and were simply left to fend for themselves and ultimately die.

Dr Martin Couney offered desperate parents a pioneering solution that was as expensive as it was experimental - and came up with a very unusual way of covering the costs.

It was Coney Island in the early 1900’s. Beyond the Four-Legged Woman, the sword swallowers, and “Lionel the Lion-Faced Man,” was an entirely different exhibit: rows of tiny, premature human babies living in glass incubators.

The brainchild of this exhibit was Dr. Martin Couney, an enigmatic figure in the history of medicine. Couney created and ran incubator-baby exhibits on the island from 1903 to the early 1940s.

Behind the gaudy facade, premature babies were fighting for their lives, attended by a team of medical professionals.To see them, punters paid 25 cents.The public funding paid for the expensive care, which cost about $15 a day in 1903 (the equivalent of $405 today) per incubator.

Couney was in the lifesaving business, and he took it seriously. The exhibit was immaculate. When new children arrived, dropped off by panicked parents who knew Couney could help them where hospitals could not, they were immediately bathed, rubbed with alcohol and swaddled tight, then “placed in an incubator kept at 96 or so degrees, depending on the patient. Every two hours, those who could suckle were carried upstairs on a tiny elevator and fed by breast by wet nurses who lived in the building. The rest [were fed by] a funneled spoon. The smallest baby Couney handled is reported to have weighed a pound and a half.

His nurses all wore starched white uniforms and the facility was always spotlessly clean.

An early advocate of breast feeding, if he caught his wet nurses smoking or drinking they were sacked on the spot. He even employed a cook to make healthy meals for them.

The incubators themselves were a medical miracle, 40 years ahead of what was being developed in America at that time.

Each incubator was made of steel and glass and stood on legs, about 5ft tall. A water boiler on the outside supplied hot water to a pipe running underneath a bed of mesh, upon which the baby slept.

Race, economic class, and social status were never factors in his decision to treat and Couney never charged the parents for the babies care.The names were always kept anonymous, and in later years the doctor would stage reunions of his “graduates.

According to historian Jeffrey Baker, Couney’s exhibits “offered a standard of technological care not matched in any hospital of the time.”

Throughout his decades of saving babies, Couney understood there were better options. He tried to sell, or even donate, his incubators to hospitals, but they didn’t want them. He even offered all his incubators to the city of New York in 1940, but was turned down.

In a career spanning nearly half a century he claimed to have saved nearly 6,500 babies with a success rate of 85 per cent, according to the Coney Island History

In 1943, Cornell New York Hospital opened the city’s first dedicated premature infant station. As more hospitals began to adopt incubators and his techniques, Couney closed the show at Coney Island. He said his work was done.

Today, one in 10 babies born in the United States is premature, but their chance of survival is vastly improved—thanks to Couney and the carnival babies.

Exploring some interesting simulations, quite liked this. It looks like crumpled sheets of paper. 20 random permutations. #mathart #excelart #excelmathart https://www.instagram.com/p/ByWB874Hlew/?igshid=fftifhitc9wh

Turns out the patterns from the previous post tesselate quite nicely (of course because they have six fold rotational symmetry 😁) #Mathart #excelart #excelmathart #eulerspiral #symmetry https://www.instagram.com/p/BwvBYYWBi9f/?igshid=xi7xy2bnihy5

[excelmathart]

What happens when you mix euler spirals, random walk and rotational symmetry? Well something like this of coarse. #Mathart #excelart #excelmathart #eulerspiral #geometry #rotation https://www.instagram.com/p/Bwn6hIShzjB/?utm_source=ig_tumblr_share&igshid=1i732ct4pk2nh

Really enjoy the detail in these #goldenratio inspired spirals. Even printing at 900x900 doesnt do it justice :) Have a few prints near this size if anyone is interested. #mathart #excelart #excelmathart #geometry https://www.instagram.com/p/BwdEkLyBgbz/?utm_source=ig_tumblr_share&igshid=1scwefmnllloj

Look deep into my triangle! You are slowly starting to relax. you are falling into a deep sleep. Quite hypnotic to look at 😁 Enjoy! Swipe right for more turns #Mathart #excelart #excelmathart https://www.instagram.com/p/BwbOFWKBGi5/?utm_source=ig_tumblr_share&igshid=ocozybas2d6w

Some fun with curves of pursuit. If you look carefully, you will see this is made only of lines :) #Mathart #excelart #excelmathart #geometry #curvesofpursuit https://www.instagram.com/p/BwVFXK8BXi3/?utm_source=ig_tumblr_share&igshid=i3m4b1odrt1y

Love this animation from a few years back. If you look carefully none of these squares turn. just keep sliding. just keep sliding 😁 #Mathart #excelart #excelmathart #geometry #fractal https://www.instagram.com/p/BwUKdBmBMUz/?utm_source=ig_tumblr_share&igshid=zdvitpfvdjxi

More detail and iteration than the previous one, makes me think of a cross between Sauron's eye and a cockle shell 😉 #mathart #excelart #excelmathart #geometry https://www.instagram.com/p/BwRT3Xhhjka/?utm_source=ig_tumblr_share&igshid=1kecdq7cf86um

This came out nicely, there are quite few in the series :) #mathart #excelmathart #excelart #geometry https://www.instagram.com/p/BwO3d1xhLie/?utm_source=ig_tumblr_share&igshid=anzetigp6cdj
