Reuben A. Whitmore (hermit)

Reuben A. Whitmore (July 23, 1857 - February 16, 1935) was an American hermit, sometimes referred to as the Catoctin Hermit (after the Catoctin Mountain) or Buffalo Bill, notably a long-time resident of the wilderness around Rocky Ridge, along Fishing Creek, in Frederick County, Maryland.

Whitmore claimed in March of 1897, after being arrested and brought into the City of Frederick, to have devised a perpetual motion machine and that he had planned to sell the patent rights to an unnamed "Northern gentleman," but that the would-be buyer did not have the million dollars commanded for the sale. He was committed to the Montevue Hospital, only to be released again just over a week later, thereafter returning to his wild life.

In his later years, he returned to society, coming to reside near Lewistown, Maryland, where he was the victim of an assault and robbery by two unidentified individuals in July of 1929.
