DONWILHELMS devoted his professional life to lunar and planetary geology after obtaining degrees in geology from Pomona College and the University of California, Los Angeles. His 24-year career at the U.S. Geological Survey's Menlo Park, California, office of the Branch of Astrogeology spanned the era of American robotic and human exploration of the Moon. Dr. Wilhelms has become a leading authority on the Moon's geology, specializing in stratigraphy and geologic mapping, and he played a major role in the selection of target s for Lunar Orbiter photography and sites for Apollo landings. He helped train the astronauts in field and lunar geology during a year at the Manned Spacecraft Center in Houston and in preflight briefings. He is the author of the book The Geologic History of the Moon and of numerous maps and article s on lunar and planetary geology. Since his official retirement in August 1986 he has continued to study the Moon, Mars, and the Jovian satellite Ganymede. He is a fellow of the American Geophysical Union and the American Association for the Advancement of Science, and has received the Geological Society of America's G. K.
