Mr. District Attorney is a popular radio crime drama, produced by Samuel Bischoff, which aired on NBC and ABC from April 3, 1939,
to June 13, 1952 (and in transcribed syndication through 1953). The series focused on a crusading D.A., initially known only as "Mister District Attorney,"
or "Chief", and was later translated to television. On television the D.A. had a name, Paul Garrett, and the radio version picked up this name in the final
years when David Brian played the role. A key figure in the dramas was the D.A.'s secretary, Edith Miller (Vicki Vola). Created, written, and directed by
former law student Ed Byron, the series was inspired by the early years of New York Governor Thomas E. Dewey. It was Dewey's public war against racketeering
which led to his election as governor. Phillips H. Lord, creator of Gang Busters, helped to develop the concept and coined the title. Byron lent an air of
accuracy and immediacy to his scripts through close study of crime statistics, a library of criminology texts, following the newspapers, and even going around
rough bars to gain tips, background, and color from crooks and police alike. His techniques sometimes enabled Byron to predict major crime waves before the
news broke. Produced throughout its run in New York City, the series began as a 15-minute serial, becoming a half-hour, self-contained series three months
later as a summer replacement for The Bob Hope Show beginning June 27, 1939. During 1942, Mr. District Attorney began battling Nazis, leading to conflicts
with the FBI when the scripts reflected life too closely. The program was sponsored by Bristol-Myers.
