Westwood is a district in western Los Angeles, California, United States. Westwood is best known as the home of the University of California, Los Angeles (UCLA). The eastern portions of the district are often thought of as a distinctly different neighborhood, Holmby Hills. Westwood was carved from the old Wolfskill Farm, a 3,000 acre (12 kmē) tract that was purchased in 1919 by wealthy retailer Arthur Letts. Letts' son-in-law, Harold Janss, was vice president of Janss Investment Company, which developed the area and started advertising new homes in 1922.
