1971-73: Mathematician, Bell Labs, Holmdel, New Jersey; Visiting Associate Professor of Mathematics, Savannah State College1973-74; Visiting Assistant Professor of Mathematics, Amherst College 1974-75:
In 1975, Dr. Lahr hired by Dartmouth as an Assistant Professor of Mathematics, Dartmouth College. In 1981 he became Associate Professor, and Associate Dean of Faculty for Sciences, and Dean of Graduate Studies; In 1984 he became Professor of Mathematics and Computer Science, and Dean of the Faculty (until 1989). At Dartmouth College, Professor Lahr has had two Ph.D. students: Charles Jones (1978) and Daniel Sloughter (1981)
