One Round Hogan, also known as "Jack Hogan," was a popular San Francisco area lightweight boxer during the city's four-round era of the early 1910s. (At this time San Francisco preferred four-rounders, as opposed to the ten-rounders staged in the Los Angeles area.  This is to be distinguished from California's state-wide Four-Round Era that started in late 1914.) He also had some success on the East Coast and even "won the hearts" of British fans. 
He was credited with scoring 18 consecutive first round knockouts for a number of years. However, this was never confirmed, and Young Otto became the official record holder for most consecutive first-round knockouts until that record was broken in 2006 by Edwin Valero.
In early 1929, Hogan sued a motion picture company for $75,000, claiming his reputation was ridiculed and harmed by a 1927 boxing movie that used his alias for the main character.
Hogan was later a referee in California.
