The story
Hawk & Parr was formed in 1914 as the partnership of architects J. W. Hawk and J. O. Parr. Hawk had been in practice in Oklahoma City since 1899, Parr since 1910. Hawk retired from practice in 1932, but Parr continued to practice under the Hawk & Parr name until his death in 1930.
After Parr's death, the firm was reorganized as Parr, Frye & Aderhold by William G. Parr, his son, Harvey D. Frye and George Aderhold. In 1941 it became Parr & Aderhold. Aderhold withdrew from the firm in 1961 to become architectural director for the Federal Bureau of Prisons. Parr briefly worked alone before forming the partnership of Parr & Watkins with Dudley Watkins in 1962. Parr returned to independent practice in 1967. He practiced into the 1980s and died in 1994.
