The Boston Blackie radio series,
starring Chester Morris, began June 23, 1944, on NBC
as a summer replacement for The Amos 'n' Andy Show.
Boston Blackie was "an enemy to those who make him
an enemy, friend to those who have no friend."
Sponsored by Rinso, the series continued until
September 15 of that year. Lesley Woods appeared as
Blackie's girlfriend Mary Wesley, and Harlow Wilcox
was the shows announcer. On April 11, 1945, Richard
Kollmar took over the title role in a radio series
syndicated by Frederic W. Ziv to Mutual and other
network outlets. Over 200 episodes of this series
were produced between 1944 and October 25, 1950.
