Fisher & Fisher was an architectural firm based in Denver, Colorado named for partners William Ellsworth Fisher (1871–1937) and Arthur Addison Fisher (1878–1965). The firm was founded in 1892 by William Ellsworth Fisher as William Fisher, Architect. After ten years in practice alone, mainly designing starter homes, he partnered with Daniel Riggs Huntington from 1901 to 1905 as Fisher & Huntington, during which time the firm designed increasingly expensive residences and also commercial buildings. The firm then once more became William Fisher, Architect until 1907, when William was joined by his younger brother Arthur Addison Fisher; they worked together as William Fisher Architect and Brother until 1910 and then as William E. Fisher and Arthur A. Fisher, Architects until William's death in
