Wikipedia: Don Marquis
Donald Robert Perry Marquis (/ˈmɑːrkwɪs/ mar-kwis; July 29, 1878 in Walnut, Illinois – December 29, 1937 in New York City) was a humorist, journalist, and author. He was variously a novelist, poet, newspaper columnist, and playwright. He is remembered best for creating the characters “Archy” and “Mehitabel”, supposed authors of humorous verse. During his lifetime he was equally famous for creating another fictitious character, “the Old Soak,” who was the subject of two books, a hit Broadway play (1922–23), a silent movie (1926) and a talkie (1937).
