In 1956 Burr was the star of CBS Radio's "Fort Laramie", an adult Western drama produced, written and directed by the creators of "Gunsmoke". He played the role of Lee Quince, captain of the cavalry, in the series set at a post-Civil War military post where disease, boredom, the elements and the uncharted terrain were the greatest enemies of "ordinary men who lived in extraordinary times". The half-hour transcribed program aired Sundays at 5:30 p.m. ET January 22 – October 28, 1956. Burr told columnist Sheilah Graham that he had received 1,500 fan letters after the first broadcasts, and he continued to receive letters praising the show's authenticity and presentation of human dignity.
