Key's most famous creation, the single-panel "Hazel", about a wry and bossy household maid, came to Key in 1943 in a dream that he drew the next morning and sent to "The Saturday Evening Post", where it was accepted and began running regularly. He soon afterward gave the character a name and employment at the Baxter household. In 2008, the cartoonist's son, Peter Key, said, "He picked the name Hazel out of the air, but there was an editor at "The Post" who had a sister named Hazel. She thought her brother came up with the name, and she didn’t speak to him for two years."
