Michael David Plummer (born 1937) is a retired mathematics professor from Vanderbilt University.
He then went to Wabash College in Crawfordsville, Indiana on an honor scholarship, with a double major in mathematics and physics.
He then took a graduate fellowship in physics at the University of Michigan, but after one year of the program, switched to mathematics; in 1966 he was awarded his Ph.D., with a thesis supervised by Frank Harary.
[1][2] After postdoctoral studies at Yale University from 1966 to 1968, Plummer took an assistant professorship in the recently formed Department of Computer Science at City College of New York which was part of the School of Engineering.
