Fritz Leiber, Jr. (1910-1992) was an American writer of fantasy, horror and science fiction. He was also an expert chess player and a champion fencer. He married Jonquil Stephens on January 16, 1936, and their son Justin Leiber was born in 1938. Leiber’s death occurred a few weeks after a physical collapse while traveling from a science fiction convention in London, Ontario, with Skinner. The cause of his death was given as "organic brain disease." Leiber’s own literary criticism, including several ground-breaking essays on Lovecraft, was collected in the volume Fafhrd and Me (1990).
