Sidney West Graham is a mathematician interested in analytic number theory and professor at Central Michigan University. His received his Ph.D., which was supervised by Hugh Montgomery, from the University of Michigan in 1977. In his Ph.D. thesis he lowered the upper bound for Linnik's constant to 36 and subsequently reduced the bound further to 20. He has Erdos number of 1 through a joint paper with Paul Erdos in 1996.
