Early life and career Frank Klaus was born on December 30, 1887, to German-American parents in Turtle Creek, Pennsylvania, near Pittsburgh. He worked as a young man at the Westinghouse Machine Shop, and also mined coal with his father.
He started boxing training early and after winning an amateur tournament at East Pittsburgh's Wilmerding Athletic Club was recognized to have boxing promise by local boxing mentor George Engel. He began his amateur career as early as 1904, and in February 1905 had three round wins on points in Pittsburgh against Frank Walton, and James Harris.
On October 18, 1911, Klaus defeated the great contender Leo Houck in a newspaper win by both the Philadelphia Item and the Philadelphia Record. During his career, the Pennsylvania-born middleweight fought some of the greatest welter, middle, and light heavyweights of his era, including Jack Dillon, Battling Levinsky, Mike Gibbons, Harry Greb, and Al McCoy.

In a return non-title match on December 23, 1913, Chip defeated Klaus again. In the fifth round of six, the referee stopped the fight resulting in a technical knockout after Chip knocked Klaus to the mat for a second time.
