According to the 1920 Tulsa City Directory, the address of the Drexel Building was 319 S. Main. This building is significant in Tulsa's history because according to the Tulsa Daily World, Wednesday, 6/1/1921, it was this building where Dick Rowland, a negro bootblack, was arrested for assaulting a white girl in an elevator. The Tulsa Race Riots broke out soon afterward.
