Born in Chicago, Gorey came from a colourful family; his parents, Helen Dunham Garvey and Edward Lee Gorey, divorced in 1936 when he was 11, then remarried in 1952 when he was 27. One of his step-mothers was Corinna Mura, a cabaret singer who had a brief role in the classic film Casablanca. His father was briefly a journalist. Gorey's maternal great-grandmother, Helen St. John Garvey, was a popular 19th century greeting card writer/artist, from whom he claimed to have inherited his talents. He attended a variety of local grade schools and then the Francis W. Parker School. He spent 1944–1946 in the Army at Dugway Proving Ground in Utah, and then attended Harvard University from 1946 to 1950, where he studied French and roomed with future poet Frank O'Hara. Although he would frequently state that his formal art training was "negligible", Gorey studied art for one semester at The School of The Art Institute of Chicago in 1943, eventually becoming a professional illustrator. From 1953 to 1960, he lived in New York City and worked for the Art Department of Doubleday Anchor, illustrating book covers and in some cases adding illustrations to the text. He has illustrated works as diverse as Dracula by Bram Stoker, The War of the Worlds by H. G. Wells, and Old Possum's Book of Practical Cats by T. S. Eliot. In later years he illustrated many children's books by John Bellairs, as well as books in several series begun by Bellairs and continued by other authors after his death.

"What do I like about writing for children? Everything," says Florence Parry Heide, the award-winning author of more than sixty children’s books, including the classic THE SHRINKING OF TREEHORN, illustrated by Edward Gorey. "I like the connection with children," the author says. "I like the connection with all kinds of book people. And I like the connection with my childhood self, which is the most of me. It is the most welcome and familiar of worlds. There miracles abound—indeed it is magical that something I might think of can be put into words, stories, ideas, and that those words end up in the heads of readers I will never meet." Florence Parry Heide wrote SOME THINGS ARE SCARY, a humorous look at childhood bugaboos, more than thirty years ago. "I had finished another book and was in the mood to write something else," she says. "I decided to get some kindling from the garage, reached into the kindling box and—good grief!—grabbed something soft and mushy. I fled back to the house, scared to death." A brave return visit to the kindling box revealed the object of terror to be nothing more than a discarded wet sponge, but the thought remained: some things are scary. As she recalls, "What scared me as a child was that I’d never learn how to be a real grownup—and the fact is, I never did find out how it goes." One thing Florence Parry Heide does have a good handle on is the concept of friendship, in all its humorous manifestations. THAT’S WHAT FRIENDS ARE FOR, a tongue-in-cheek tale cowritten with Sylvia Van Clief in 1967, pokes at the tendency of well-meaning friends to offer advice instead of help, and presents a valuable lesson about what true friendship means. "One of my many (true) sayings is ‘A new friend is around the corner of every single day,’ " the author declares. "Also true: Friendships last. And last." Born and raised in Pennsylvania, Florence Parry Heide worked in advertising and public relations in New York City before returning to Pittsburgh during World War II. After the war, she and her husband moved to Wisconsin, where they raised five children, two of whom have cowritten critically acclaimed books with their mother. Florence Parry Heide now lives in Wisconsin.
