Morgan, Walls & Clements earliest precursor, Kysor & Hennessy, consisted of partners
Ezra F. Kysor and
John F. Hennessy, then in 1880, Hennessy left and the firm's draftsman Octavius Morgan was promoted to partner, creating Kysor & Morgan. John A. Walls joined in 1886 to create Kysor, Morgan and Walls, and Kysor retired in 1890, resulting in Morgan and Walls. Around 1910, Morgan's son O.W. Morgan was promoted, creating Morgan, Walls and Morgan, then the elder Morgan retired and designer
Stiles O. Clements was promoted, resulting in Morgan, Walls and Clements. Morgan, Walls and Clements hit its stride with a series of theaters and commercial projects around
MacArthur Park. Clements often worked in Spanish Colonial revival and Mayan revival styles, but their major project was the black
Art Deco Richfield Tower, a commanding presence in downtown from its 1928 completion to its 1969 destruction. Walls did not live to see the completion of the building, as he had died in 1922. Clements left the firm in 1937 to start his own practice, Stiles O. Clements & Associates, where he remained until his retirement in 1965. ==Works==
