The library was established by William Andrews Clark, Jr. (1877 – 1934), a prominent philanthropist and founder of the Los Angeles Philharmonic Orchestra (1919). The library is named in honor of his father, Sen. William Andrews Clark, who had built a mining fortune in Montana. Clark lived at the corner of Adams Blvd. and Cimarron Street.
Between 1924 and 1926 he engaged prominent architect Robert D. Farquhar to design a library for his rare books and manuscripts, renowned for their collections of 17th- and 18th-century English literature and history. The library was bequeathed to the University of California at Los Angeles in 1934.
