The Shoemaker Lecture is part of the AGU series of Bowie lectures that were inaugurated in 1989 at the 50th presentation of the William Bowie Medal, the AGU's highest honor.
The Shoemaker lecture is named for Eugene Shoemaker, an outstanding geologist and planetary scientist known for his study of impact craters and lunar science. Shoemaker was awarded the Bowie Medal in 1996 and was killed in an auto accident in Australia in 1997. His citation for the Bowie Medal illuminates his illustrious career that was crowned with the discovery that Comet Shoemaker/Levy-9 would impact Jupiter in 1994.
The Whipple Lecture is given by the winner of the Whipple Award. Fred Whipple, a gifted astronomer most noted for his work on comets, was an AGU Fellow elected in 1962 and the Section's first Whipple Award honoree in 1990.

Sagan was President of the Section from 1980 to 1982. He was a founder of The Planetary Society and was Editor in Chief of Icarus for 12 years. An inspiration to several generations of young planetary scientists he died in 1996.
