Catherine Rose Mulholland,
granddaughter of William Mulholland, former Chief Superintendent of the Los Angeles
Department of Water and Power, was a historian, writer, civic leader, and public speaker in
the San Fernando Valley and the greater Los Angeles area, where she spent much of her life.
Catherine Mulholland Collection documents her personal and
professional life, chronicles the life of her grandfather, William Mulholland, and provides
a unique perspective for considering the early social, political and economic history of the
greater Los Angeles area. Most significantly, materials contained in this collection
demonstrate the many complex issues involved in Los Angeles water history, as well as the
important roles played by politicians and political movements, private business and
industry, civic organizations, and local, state, and federal governmental agencies in the
quest to provide water to the ever-expanding population of Los Angeles.
Catherine Rose Mulholland was born at Hollywood Methodist Hospital in Hollywood, California
on April 7, 1923, the first of three children born to William "Perry" and Addie Camelia Haas
Mulholland. Perry (1892-1962) was the eldest son of William Mulholland (1855-1935), former
Chief Superintendent of the Los Angeles Department of Water and Power, and Lillie Ferguson
Mulholland (1867-1915), daughter of James (1831-1910) and Francis Ann Fish Ferguson
(1837-1926). Addie (1896-1980) was the eldest daughter of John (1867-1917) and Katie May
Ijams Haas (1877-1968), early settlers in the San Fernando Valley. Catherine was raised on a
citrus and walnut ranch known as the Mulholland Orchard Ranch, located at the west end of
the San Fernando Valley between the towns of Chatsworth and Northridge, an area formerly
known as Zelzah.
