Chandu the Magician was heard on several different networks and aired in two distinctly different series, one in the 1930s and a revival 12 years later. The series was created by Harry A. Earnshaw and Raymond R. Morgan.
Launched in 1931 on KHJ in Los Angeles, the series was soon heard through the West Coast when broadcast on the Don Lee Network. It was then heard, starting in February 1932, over WOR in the East. Nationally, it aired over Mutual starting October 8, 1932. The series was sponsored by White King Soap in the West and by Beech Nut Gum in the East.
Gayne Whitman played the lead role of American-born Frank Chandler, who had learned occult secrets from a yogi in India. Known as Chandu, he possessed several supernatural skills, including astral projection, teleportation and the ability to create illusions. Chandu's goal was to "go forth with his youth and strength to conquer the evil that threatens mankind". His sister, Dorothy Regent, was portrayed by Margaret MacDonald.
In 1935, the production moved to WGN Chicago with a new cast, including Howard Hoffman in the title role and Cornelia Osgood as Dorothy.
Twelve years later, the series was revived on Mutual June 28, 1948 as a 15-minute weekday program, starring Tom Collins as Chandu and Luis van Rooten as the villainous Roxor plotting world domination. With Howard Culver as the announcer and music by organist Korla Pandit, that series continued until January 28, 1949. The serial continuity was dropped February 2, 1949 in favor of 30-minute episodes, each with a self-contained storyline, continuing in that format until April 28, 1949. Culver often read commercials with Pandit's organ music in the background.
On October 15, 1949, Chandu the Magician moved to ABC where it was heard Saturdays at 7:30pm until June and then on Wednesdays at 9:30pm. The last broadcast was September 6, 1950. (Source: wikipedia.org)
