J. E. (John Everts) Lamar

John Everts Lamar (1897–1979) was an American geologist whose career was closely tied to the Illinois State Geological Survey. After studying at the University of Chicago, he joined the Survey in 1920 and, aside from a brief period of teaching, spent the rest of his professional life there.

He became a specialist in industrial and nonfuel minerals, eventually leading the Survey’s Industrial Minerals Division. Colleagues remembered him as an important source of practical knowledge about Illinois geology, especially limestone, dolomite, clays, and other materials with everyday industrial uses. His work earned national recognition, including the Hal Williams Hardinge Award in 1971.

Even after retiring in 1966, Lamar continued sharing his knowledge for years. A memorial published by the Geological Society of America describes him as a widely respected figure in geology whose research and guidance helped shape the understanding and development of Illinois mineral resources.
