Pearl Zane Grey (January 31, 1872 – October 23, 1939) was an American author best known for his popular adventure novels and stories that presented an idealized image of the Old West. Riders of the Purple Sage (1912) was his best-selling book. In addition to the success of his printed works, they later had second lives and continuing influence when adapted as films and TV productions. As of 2007, 110 films, one TV episode, and a series, Dick Powell's Zane Grey Theater, had been made that were based loosely on his novels and short stories.
