Born in Bowie, Texas, Kerr attended the University of Colorado Boulder and received a Bachelor of Arts degree from the University of Oklahoma in 1923 and a Bachelor of Science degree from University of Central Oklahoma in 1923. He read law to enter the bar in 1927. He was in private practice in Cheyenne, Wyoming from 1927 to 1929. He was an Assistant United States Attorney for the District of Wyoming from 1930 to 1933. He was the Attorney General of Wyoming from 1939 to 1943, and an attorney for the Wyoming Senate in 1943. He was in the United States Army from 1943 to 1946 and became a major.[1] During World War II, he served in the Allied Command in Italy and became head of the legal division in that region.[1] In 1945, he reorganized the civilian courts in Austria.[1]
On October 22, 1955, Kerr received a recess appointment from President Dwight D.

Formally nominated to the same seat by President Eisenhower on January 12, 1956, he was confirmed by the United States Senate on March 1, 1956, and received his commission the following day.
