"Doc Savage" Magazine ceased publication in 1949. Of the 181 Doc Savage novels published by Street and Smith, 179 were credited to Kenneth Robeson; and all but twenty were written by Dent. The first novel, "The Man of Bronze", used the name Kenneth Roberts, but this was changed after it was discovered that there was another author named Kenneth Roberts. The March 1944 issue, "The Derelict of Skull Shoal", was accidentally credited to Lester Dent. This was the only time during the run of the magazine that Dent's real name was used. Following his tenure on "Doc Savage", Dent found continuing success as a mystery and western writer. His last published short story was a Western entitled "Savage Challenge", published in the February 22, 1958 issue of the "Saturday Evening Post". A last novel, "Lady in Peril", was released as half of an Ace Double the month that Lester died.
