Ivanov supervised the capture of adult chimpanzees in the interior of the colony, which were brought to Conakry and kept in cages in the botanical gardens. On February 28, 1927, Ivanov artificially inseminated two female chimpanzees with human sperm (not his own or his son’s). On June 25, he injected a third chimpanzee with human sperm. The Ivanovs left Africa in July with thirteen chimps, including the three used in his experiments. They already knew before leaving that the first two chimpanzees had failed to become pregnant. The third died in France, and was also found not to have been pregnant. The remaining chimps were sent to a new primate station at Sukhumi.
The production of records on X-ray film was a dissident practice in the former USSR during the Cold War from 1946 to the early 1960s, viewed as anti-USSR activity and punished by 3-7 years of prison. A master disk was pressed onto already-exposed and heated X-ray film, in order to make a kind of phonographic recording, whose barely visible grooves were etched on skulls, chest cavities, and spinal cords of the Soviet citizens. Until Stalin’s death, “Music on Bones” - as it was referred to in KGB documents and anti-propaganda movies circulated by the Soviet Government - was the only way to gain access to Western hits.
This is probably THE COOLEST thing I have ever seen in a museum… they even had headphones hooked up to listen to the real recordings yourself!
Oh man, I’d love to listen to them
