Catherine Rose Mulholland (April 8, 1923 â July 6, 2011) was an American historian and author known for her works on the history of Los Angeles and the San Fernando Valley. As the granddaughter of William Mulholland, the chief engineer responsible for constructing the Los Angeles Aqueduct, she offered a unique perspective on the region's development.
Born in Hollywood, California in 1923, Catherine Mulholland grew up on her family's 600-acre ranch in the western San Fernando Valley. Her parents were Perry Mulholland, William's eldest son, and Addie, the daughter of Calabasas homesteaders. She attended multiple schools during her youth, including North Hollywood Junior High School, Marlborough School for Girls, and graduated from Canoga Park High School in 1940.
She studied musical improvisation under jazz teacher Lloyd Reese, leading to a friendship with legendary bassist Charles Mingus. This relationship provided her with deep insights into the racial challenges of the time. Mulholland earned a degree in English from UC Berkeley and later a masterâÂÂs from Columbia University, becoming friends with prominent writers such as Allen Ginsberg and Jack Kerouac. She also studied for a Ph.D. in English literature at UC Berkeley but did not finish her degree.
In the 1950s, Mulholland wrote a successful play about her early life, entitled A Wedding in the Valley, which won the James D. Phelan Award for significant accomplishments by young California writers and artists.
Beginning in 1976, Mulholland authored several books focusing on Los Angeles' history, including:
Over the final 30 years of her life, Catherine Mulholland consistently stated in various interviews that she saw herself as the protector of her grandfather's legacy and reputation. She firmly denied his involvement in conspiracies to steal water from the Owens Valley, but she acknowledged that the St. Francis Dam disaster was, at least in part, his responsibility. She fought against the myths surrounding William Mulholland, many of which were fueled by the 1974 film Chinatown. Additionally, Catherine rejected the portrayal of her grandfather as a mere "lackey" to influential industrialists and politicians, a role often attributed to him. Her biography of William Mulholland was her opportunity to try to correct the record and reclaim his reputation.
Beyond writing, Mulholland was an active civic leader and public speaker, contributing to historical preservation and education in Southern California. Most notably, she served on the board of Los Angeles Water and Power Associates, an organization dedicated to educating the public about water-related issues.
Mulholland had a brief romantic relationship with the poet Jack Spicer before she married Gerard T. Hurley in 1949, with whom she had three children. They later divorced in 1976.
Mulholland resided in Berkeley for most of her married life, only returning to Southern California after her divorce. She lived first in Thousand Oaks, then in Chatsworth for many years, and finally in Camarillo
Catherine Mulholland died on July 6, 2011, at her home in Camarillo, California, at the age of 88.
Mulholland donated her personal papers and archives, covering multiple generations of her influential family as well as the office files of William Mulholland, to California State University, Northridge where they are preserved in the University Library in Special Collections and Archives.
In a speech in 1986, Mulholland shared her reasons for becoming a historian:
