Robert K. Bishop (1945 - 1991) was an American bondage artist, often credited as The Bishop or simply Bishop. Born in Michigan, he has been compared with John Willie and described as the "Rembrandt of bondage art". Most of Bishop's art appeared in magazines and catalogues from 1971 to the 1980's. By the mid-1990's, Bishop's art had long been out of print. The originals had largely been lost or destroyed. Even a partial reprinting in 1992-1993 was based on previously published copies.
