J. Fred Hoelzle (1859-1943) was a butcher.

Hoelzle (1859-1943) came to Ann Arbor when he was seventeen and went to work for butcher John C. Gall at his store on East Washington where Austin Diamond is now. Hoelzle married a relative of Gall's named Alice and took over the business when Gall retired. In 1893 he moved down the street to the new building at Fourth Avenue and renamed his shop the Washington Market. A 1905 promotional booklet about Ann Arbor boasted that he "supplied the tables of Ann Arbor with the best meat that the world produces, makes the best sausage on the market, keeps poultry and fish in season, gives a clean cut and full weight, is impartial and obliging and has the confidence of the best citizens."
