About the author (1981)

Larry Niven received his B.A. in mathematics in 1962. During his first year of writing, all he received were rejection slips, but his first novel, World of Ptavvs (1966), was a success and launched his career. Niven has won five Hugos and one Nebula award, testimony that his colleagues in the science fiction world respect his work. Perhaps Niven's most well-known creation is Ringworld, a distant planet that may be taken as a metaphor for Earth, as it was once great but has since fallen into decay.
