Little is known about the career of artist William C. McCauslen. Born in Steubenville, Ohio, he appears to have received some formal training as a painter but was self-taught as a sculptor. It is unknown how McCauslen came to the attention of the Joint Committee on the Library to execute the marble bust of William R. King for the Senate’s Vice Presidential Bust Collection. In 1896 McCauslen’s model was approved by the committee, and the finished work was placed in the Capitol that same year. McCauslen also completed marble busts of John Tyler and Andrew Johnson for the vice presidential series.
