Fritz Leiber has won awards too numerous to count, including the coveted Hugo and Nebula(R), and was honored as a lifetime Grand Master by the Science Fiction Writers of America. He died in 1992.
"Wonderful, magical Fritz Leiber, before whom Bradbury and Sturgeon and Norton and Goldman and Barth and Vonnegut bow, not to mention Robinson, Busby, Anderson and even yours truly, the maddest egomaniac of them all." -- Harlan Ellison, 1977
