Publications

Hetherington had a Siamese cat named Chester, who had been sired by a Siamese named Willard. Fearing that colleagues might recognize his pet's name, he thought it better to use the pet's initial. Aware that most Americans have at least two given names, he invented two more given names based on the

Reception
The unmasking of Hetherington's co-author on the ''Physical Review'' essay, which was frequently referenced, caused the co-authorship to become world-famous. The story goes that when inquiries were made to Hetherington's office at Michigan State University, and Hetherington was absent, the callers would ask to speak to the co-author instead. F. D. C. Willard appeared henceforth repeatedly in footnotes, where he was thanked for "useful contributions to the discussion" or oral communications,[ and even offered a position as a professor. F. D. C. Willard is sometimes included in lists of "Famous Cats" or "Historical Cats". As an ]April Fool's
