Fallon's family moved to Canada when he was a child. At age 18, he was in St. Louis and joined the third expedition of John C. Frémont to California. Early in 1846, Fallon stayed in Santa Cruz after Frémont visited the area. In June 1846, he raised a group of 22 Santa Cruz-area volunteers to join Fremont, appointing himself captain. When the Mexican–American War began in California with Commodore John D. Sloat's capture of Monterey on July 7, Fallon's force crossed the Santa Cruz Mountains to capture the El Pueblo de San José de Guadalupe without bloodshed, on July 11. On July 14, 1846 he received an American Flag from Sloat, which he raised over the juzgado of San Jose, the pueblo's administrative building. Fallon's volunteers then joined Fremont's California Battalion for the remainder of the war. After the war, Fallon returned briefly to San Jose, then back to Santa Cruz where he established a business as a saddler. At the beginning of the California Gold Rush in 1848, Fallon took a cargo of iron picks made in Santa Cruz to sell to the gold miners. With his share of the profits, he built a combination residence/workshop/hotel on the Mission plaza in Santa Cruz. In 1849, he married Carmel Castro Cota, daughter of local landowner Martina Cota Castro and her first husband Corporal Simon Cota, owners of Rancho Soquel. Carmel inherited one-tenth of Rancho Soquel, 3400 acres of land. In 1852, Fallon sold his plaza property to the County of Santa Cruz for use as a courthouse. Shortly thereafter, Thomas and Carmel moved their family to Texas. Following the death of their children, they returned to San Jose. In San Jose, Fallon began buying land in the area and built the Fallon House in Downtown San Jose. The house is preserved as a museum, across from the Peralta Adobe. In 1856, Fallon was a elected to the San Jose Common Council. In 1857, he was elected to the city's Board of Trustees for one year. He was a council-elected Mayor of San Jose in 1859, and served a single one-year term. According to one account, in 1876 Carmel found Thomas and the family maid in a compromising position, and filed for divorce. Carmel used the divorce settlement to build several hotels and other buildings, including the Carmel Fallon Building at 1800 Market Street in San Francisco, now part of the San Francisco LGBT Community Center. Thomas Fallon died in San Francisco in 1885.
Legacy
In the 1980s, San Jose MayorTom McEnery had the city commission a statue of Fallon raising the U.S. flag in San Jose at a cost of over $800,000. The statue was completed in 1988, and was scheduled to be located in the City Park Plaza near the site of the flag raising. However local groups, including Hispanic Americans, protested that Fallon represented American imperialism and repression of the Mexican population. The statue was stored until 2002, when it was finally displayed in Pellier Park northwest of the original proposed location, near Julian and St. James Streets.
