Chauncey Addison Day (Chon was a college nickname) was born in Chatham, New Jersey, USA, and attended Lehigh University in 1926, where he drew for the college's humour magazine, 'The Burr'. However, he left after just one year and later enrolled in 1929 at New York City's Art Students League. There he studied under Boardman Robinson, George Bridgman and John Sloan. It was in that same year, 1929, that his cartoons were first published in national magazines. His gentle monk Sebastian was born in the unclerical atmosphere of Toots Shor's restaurant in New York when Day was lunching with Gurney Williams, humour Editor of 'Look' magazine. Thereafter he appeared regularly in the pages of 'Look'. He also produced cartoons for such as 'The New Yorker'. the 'Saturday Evening Post' and other internationally famous magazines. When he died in 2000 he had been the 'Saturday Evening Post's' longest running cartoonist for more than half a century. He received the National Cartoonists Society Gag Cartoon Award for 1956, 1962 and 1970, plus their Special Features Award for Brother Sebastian in 1969. Instead of working in New York, Day chose to live in Westerly, Rhode Island where he conducted most of his business by mail. He stated that he moved there 'to get away from commuters'. During the summer months he would devote his time to sailing, fishing and clam digging and he worked mostly at night, after the house had stopped pulsating from the activities of his three sons. He once said, 'The natives in town think I'm a bum, or on a night shift somewhere, or a bookie.' He explained to them that he was retired and added, off the record, 'That's as good as anything, I guess, after 25 years of cartooning.' He died in 2000.
