Hyman Kaplan, or H*Y*M*A*N K*A*P*L*A*N as he habitually signs himself, is a fictional character in a series of well-received, humorous stories by Leo Rosten, published under the pseudonym "Leonard Q. Ross" in The New Yorker in the 1930s and later collected in two books, The Education of H*Y*M*A*N K*A*P*L*A*N and The Return of H*Y*M*A*N K*A*P*L*A*N. Rosten noted that he was frequently asked if Mr Kaplan was his alter ego, and that he often felt it was the other way around. Rosten rewrote the two books as one, with many changes, published as O K*A*P*L*A*N! My K*A*P*L*A*N! in 1976.
