Today in Heritage History, November 1, 1939, the Journal of Science and Medicine reports the first successful instance of artificial insemination performed on an animal (a rabbit). Lithuanian Professor Ivan Yerkenoff, responsible for the insemination was witnessed earlier that evening dining with the rabbit at a posh New York City French Restaurant. To alleviate his protracted scientific guilt, Professor Yerkenoff went on to eventually marry “Bunny” O’Hare later that year, and fathered an additional 200 bunnies.
