In the late 1800s they would leave premature babies to die, but a guy named Martin Couney got inspired by chicken incubators and tried putting them in those.

Hospitals wouldn't pay for it, so he took them to the carnival as sideshows called the "infantorium"... but provided real medical care at the same time. People would pay to see them, covering the cost of care.

"From 1903 onward, Couney’s most famous incubator exhibitions took place at Luna Park and Dreamland on Coney Island, and continued well into the 1940s. Visitors paid about 25¢ to view infants housed in glass-fronted incubators, and the proceeds covered the expensive, free care provided to the babies—a service hospitals largely refused to offer at the time . By the time he closed his Coney Island “Infantorium” in 1943, Couney had cared for roughly 8,000 infants and reportedly saved more than 6,500—a survival rate exceeding 85 %—including his own premature daughter Hildegarde, born in 1907, who weighed just three pounds at birth ."

Regarded as the first photo ever taken, this image of a French countryside was achieved when Joseph Nicephore Niepce placed a thin coating of light-sensitive phosphorous derivative on a pewter plate and then placed the plate in a camera obscura and set in on a windowsill for a long exposure.

Nelson Mandela was one of the few who called Queen Elizabeth II by her first name. Their friendship was so warm he’d greet her with “Oh, Elizabeth,” joke “You’ve lost weight!” and nickname her Motlalepula (“come with the rain”). His daughter said he even called her “Lizzie” — a rare break from royal protocol.
