John E. Weaver (1884-1956) was a leading expert on grasses, both as natural populations and as crops. During his career as a faculty member at NU, Weaver published many works regarding vegetation and ecology of prairies and published the first American ecology textbook. His reputation as a world-renowned plant ecologist attracted students from Nebraska and beyond to study range management in agronomy. An Iowa native, Weaver earned his B.S. and master's degrees from the University of Nebraska, and his doctorate from the University of Minnesota. He joined the faculty as an assistant professor in 1915 and became a full professor in 1917; he retired in 1952.
