Originally from Iowa, he graduated from Lake Forest College before attending Yale University for M.A., M.Phil.
In The Unsteady March, Klinkner and Rogers Smith argue America's record of race relations cannot be categorized as consistent, gradual advancement towards equality but rather as a series of dramatic moments where multiple factors aligned to advance or hinder progress.
