Letts arrived in the Los Angeles, California area in 1896. At the corner of Fourth and Broadway, then on the far southern edge of the downtown Los Angeles business district, the J. A. Williams & Co. Dry Goods Store had gone bankrupt. With the help of an influential friend, who was impressed with Letts' knowledge of that type of business, a loan of $5000 was secured from the Los Angeles National Bank, and opened his business on February 24, 1896. He named the department store The Broadway,
Bullock's Department Store
Arthur Letts was the 'behind the scenes' financial founder and owner of Bullock's department store, and put John Bullock from his The Broadway to direct this store. After Letts' death, Bullock and a group of investors purchased the store from the estate.
Westwood, UCLA, and, Holmby Hills
The development of Westwood, Holmby Hills, and UCLA began in 1919 when Arthur Letts Sr. purchased a portion of the Wolfskill Ranch, originally the Mexican land grantRancho San Jose de Buenos Ayres. His master plan for the prime land he had purchased in western Los Angeles. was to create a mixed development of retail, apartments, residences, estates, and significant university. He personally christened the developments Westwood and "Holmby Hills," the latter loosely derived from the name of his birthplace, a small village in England called Holdenby. Arthur Letts Sr. died suddenly in 1923, before he could realize his vision.
Letts married Florence Philp on August 25, 1886 in Toronto, Ontario, Canada. They had three children; Florence Edna, Gladys, and Arthur Letts Jr. Arthur Letts was a skilled horticulturist and avid plant collector. The grounds of his Los Feliz district, Hollywood estate Holmby House were formally laid out with wide variety of trees, shrubs, and flowers, and his cactus collection was known across the country. It was bound by Franklin Avenue, Vermont Avenue, Los Feliz Boulevard, and Laughlin Park. The gardens were open to the public for tours, with the Pacific Electric Railway stopping at it. It was his wish that the gardens be continued even after his death. Upon his death in May 1923, his wife, at the suggestion of son-in-law Harold Janss of Janss Investment Company, demolished the gardens and mansion in 1927 to subdivide and develop the land, and moved to a new residence in Holmby Hills. She had remarried by June, 1924 to Charles Quinn. Henry E. Huntington purchased many of the rare specimen cacti for his Huntington Desert Garden at his estate and Huntington Library in San Marino
