Leon

Theodore "Lee" Silver, Ph.D. (born

April 9, 1925) is an American geologist who was professor of geology at the California Institute of

Technology (Caltech). He was an instructor to the Apollo 13, 15, 16, and 17 astronaut crews. Working with the National

Aeronautics and Space Administration (NASA), he taught astronauts

how to perform field geology, essentially creating lunar field geology as a new

discipline. His training is credited with a significant improvement in the

J-Mission Apollo flights' scientific returns. After the Apollo program, he became a member of the United States National

Academy of Sciences in 1974. Currently, he is the W. M. Keck Foundation Professor

for Resource Geology, emeritus, at Caltech. Leon Silver was born

in Monticello, New York, on

April 9, 1925, as the youngest of five children.[1] His parents were Jewish immigrants from Russia and Poland, who moved the family to Waterbury, Connecticut soon

after he was born. He graduated from Crosby High

School in 1942. After

spending a year at the Colorado School of Mines before

being called up by the Navy in 1943 as a member of the Navy V-12 Program,

Silver earned his B.S. in civil engineering at the University of Colorado

Boulder in 1945. He later earned an M.S. in geology at the University of New Mexico in

1948 and a Ph.D. in geology and geochemistry at the California Institute of

Technology in 1955. Silver served in the United States Navy from

1943 to 1946, where he attained the rank of Lieutenant Junior Grade in

the Civil Engineer Corps. He

worked for the United States Geological

Survey (USGS), Mineral Deposits Branch, in Colorado and Arizona from 1947 to 1954 (field seasons only), where he

attained the status of Assistant Geologist. After completing his Ph.D., Silver

was appointed Assistant Professor of Geology (1955–1962) at Caltech; he was

later promoted to Associate Professor (1962–1965), Professor (1965–1983),

and W. M. Keck Foundation Professor

for Resource Geology (1983–1996). Since his retirement, he has been Keck

Professor Emeritus. His

main research interests are petrology, tectonics, and applications of geology and isotope geochemistry to geochronology, crustal evolution, ore deposits, and comparative planetology. While

pursuing these research interests, Silver also played a major role in the

Apollo Program's lunar geological exploration as well as on numerous national

scientific advisory boards and committees.
