Dr. Christian Bernard performed the world’s first human heart transplant in 1967, had the following to say about his observations of a chimpanzee:

"I bought two male chimps from a primate colony in Holland. They lived next to each other in separate cages for several months before I used one as a [heart] donor. When we put him to sleep in his cage in preparation for the operation, he chattered and cried incessantly. We attached no significance to this, but it must have made a great impression on his companion, for when we removed the body to the operating room, the other chimp wept bitterly and was inconsolable for days. The incident made a deep impression on me. I vowed never again to experiment with such sensitive creatures.”
