The death of legendary silent film star Rudolph Valentino at age 31 in 1926 caused mass hysteria among his fans. An estimated 100,000 people lined the streets of Manhattan to pay their respects at his funeral. A second funeral was held in Beverly Hills, setting off another wave of mourning among his fans.
Valentino's final movie "The Son of the Sheik" also featured a beautiful Arabian horse named Jadaan (the co-stars are seen in this postcard). Many fans made their way to the W.K. Kellogg Arabian Horse ranch in Pomona, California to get a glimpse of "the Valentino horse." According to one account, "Women crowded around his box stall, wore the stable door smooth pressing for a better look at the sleek stallion. And they stood to silent near-reverence when Jadaan was led riderless into the arena carrying his former master's colorful desert regalia."
The Kellogg ranch belonged to cereal magnate W.K. Kellogg’s Arabian horse ranch. Kellogg built the ranch in 1925 in Pomona to fulfill his life-long dream of breeding outstanding Arabian horses. As part of his interest in the breed, Kellogg began to collect books and research materials on the Arabian horse. Kellogg donated the horses, ranch, and other property to the state of California in 1932. Eventually the collection became part of the the Cal Poly Pomona University Library's Special Collections and Archives
Through a grant from the NHPRC, California State Polytechnic University, Pomona undertook a project to create and enhance online descriptions for 53 collections, comprising 600 linear feet from their backlog, including portions from the university archives, the records of architect John T. Lyle, and records from the local winemaking industry, Arabian horse ranching, and the Pomona Valley Historical Collection.
