I greatly admire the work of Ivan Pavlov. Turns out the Yale University archives have a piece of meat signed by Pavlov himself.
Pavlov was visiting pioneer brain surgeon Harvey Cushing when a piece of new surgical equipment caught his eye.
Pavlov was captivated by the new electrosurgical knife Cushing used in the operation, and at the end of the procedure, Cushing got a piece of beef so that the elder scientist could try his hand. After making a few incisions, Pavlov inscribed his name into the meat. “I asked him whether he wanted me to eat the meat in the hope of improving my conditional reflexes,” Cushing wrote in his journal, “or whether we could keep it in the museum, the latter we will proceed to do—’Pavlov’s beef-steak.’” A collector of old medical books and of brain tumors, when he died in 1939 Cushing bequeathed both to Yale, where his rare books would become the cornerstone for creating the Medical Historical Library.
