Industrial Minerals and Metals of Illinois
by J. E. (John Everts) Lamar
About the author
John Everts Lamar was an American geologist and specialist in industrial minerals whose career was closely tied to the Illinois State Geological Survey. According to the University of Illinois archives, he served as an instructor in geology in 1920–21, then worked as a geologist from 1921 to 1966 and led the Survey's Industrial Minerals Section from 1931 to 1966.
A memorial published by the Geological Society of America describes him as internationally recognized in his field and notes that, for nearly 50 years, he provided Illinois with information about the availability and uses of its industrial minerals. Even after retiring in 1966, he continued sharing his knowledge of Illinois geology.
Lamar wrote and co-wrote a number of survey publications on limestone, dolomite, building stone, and related resources. Those books were grounded in field knowledge and practical research, which makes them still feel clear and purposeful today.
