Fitzhugh & Byron was an architectural partnership in Phoenix, Arizona, whose partners were Lee Mason Fitzhugh (1877-1937) and Lester A. Byron (1889-1963). The firm, along with architect Henry Trost in Tucson and George Washington Smith in Ajo, Arizona, is given credit for adobe style revival in the state. The firm was established in 1910, when architect Thornton Fitzhugh returned to Los Angeles, leaving his brother, Lee Fitzhugh, in change of the office. Fitzhugh & Fitzhugh, architects, was the result. A number of its works are listed on the U.S. National Register of Historic Places.
