Frederick William Gehring[2] (7 August 1925 – 29 May 2012) was an American mathematician who worked in the area of complex analysis (quasi-conformal mappings).

His father, Carl Ernst Gehring, was a journalist who worked for the Ann Arbor News and a music critic.

His mother, Hester Reed Gehring, was a foreign language examiner for students who needed to prove competency as a requirement for their graduate degree.

She was also the daughter of John Oren Reed, a physics professor and Dean of the College of Literature, Science and the Arts at the University of Michigan.

When the war ended a few months later, Gehring was discharged from the Navy and returned to the University of Michigan, where he obtained a master's degree in mathematics.

In 1955 he returned to Ann Arbor, MI, to assume a post on the faculty of the Department of Mathematics at the University of Michigan where he worked until he retired at age 70.
