Biography: Earle Gorton Linsley 1910-2000 - University of Nebraska-Lincoln State Museum - Division of Entomology


"Gort Linsley probably is best known entomologically for his contributions to the beetle family Cerambycidae in which he was a world-renown expert. His monumental work, The Cerambycidae of North America, completed in 1977 (with John A. Chemsak) stands as the only such treatise ever attempted for the entire U.S. fauna."
