title: C.L. Shear: Gifted Mycologist, Plant Pathologist, and APS Founder.
abstract: Cornelius Lott Shear was one of the most influential plant pathologists of the early twentieth century. He was first and foremost an excellent mycologist who did pioneering research on pathogenic fungi and, as a senior pathologist with the USDA's Bureau of Plant Industry, studied important crop diseases and offered useful control measures. Shear's successful research enhanced his reputation among his fellow pathologists and allowed him to embark on what was perhaps his most significant contribution to plant pathology, his pivotal role in the creation of the American Phytopathological Society in 1908. Shear felt that an independent society dedicated to the unique needs of plant pathologists would facilitate communication and cooperation among practitioners. Between his scientific research and his role in the creation of APS, Shear stands out for the enormous impact he had on his science.
