Source-derived summary

Charley Retzlaff, alias The Duluth Dynamiter (October 28, 1904 – June 4, 1970) was an American heavyweight professional boxer from Duluth, Minnesota, United States.

Personal life

Retzlaff was born in Leonard, North Dakota.

Professional career

Retzlaff made his professional debut with a second-round knockout of Herman Raschke in March 1929. Retzlaff remained undefeated through his first 23 bouts, losing for the first time by disqualification against Antonio de la Mata in Chicago in November 1930. Retzlaff would avenge that loss with a first-round knockout in a rematch one month later. 11 more wins followed before Retzlaff suffered his next loss, to 41-23-5 Joe Sekyra in September 1931. More wins would follow, and Retzlaff carried a record of 38-2-1 into a match with fellow Minnesotan Dick Daniels. Retzlaff scored three knockdowns and a first-round knockout en route to winning the vacant Minnesota State Heavyweight Title. This title would be defended in May 1933 and again in September 1935 against Art Lasky.

Of Retzlaff, famed sportswriter Damon Runyon would say "[He is] the best-looking heavyweight prospect that has bobbed up in a long time," and "[Retzlaff is the] best of the new heavyweights.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
