John M Lewis Carl-Gustaf Rossby: National Severe Storms Laboratory, A Study in Mentorship Norman, Oklahoma Abstract Meteorologist Carl-Gustaf Rossby is examined as a mentor. In order to evaluate him, the mentor-protege concept is discussed with the benefit of existing literature on the subject and key examples from the recent history of science. In addition to standard source material, oral histories and letters of reminiscence from approxi- mately 25 former students and associates have been used. The study indicates that Rossby expected an unusually high migh' degree of independence on the part of his proteges, but that he was HiGH exceptional in his ability to engage the proteges on an intellectual basis—to scientifically excite them on issues of importance to him. Once they were entrained, however, Rossby was not inclined to follow their work closely. He surrounded himself with a cadre of exceptional teachers who complemented his own heuristic style, and he further used his influence to establish a steady stream of first-rate visitors to the institutes. In this environment that bristled with ideas and discourse, the proteges thrived. A list of Rossby's proteges and the titles of their doctoral dissertations are also included. 1.
