Jonathan Prentiss Dolliver was a Republican orator, U.S. Representative, then U.S. Senator from Iowa at the turn of the 20th century. In 1900 and 1908 Republican National Conventions, he was promoted as a vice-presidential candidate, but he was never chosen.

The 1900 Republican National Convention was held June 19 to June 21 in the Exposition Auditorium, Philadelphia, Pennsylvania. The Exposition Auditorium was located south of the University of Pennsylvania, and the later Convention Hall was constructed along the building's east wall. It was demolished in 2006.
