The Reid-Baldwin Adobe, formerly called the Hugo Reid Adobe, is an adobe house built in 1839. It is located at the Los Angeles County Arboretum and Botanic Garden in Arcadia, California. The Hugo Reid Adobe was designated a California Historic Landmark (No. 368) on April 3, 1940. The Reid Adobe was built by Scottish−Mexican Hugo Reid on the shore of what is now called Baldwin Lake, with the help of local natives. Reid received the full Mexican land grant for Rancho Santa Anita in 1845, which included 13,319 acres of land. Reid farmed some of the land and planted grape vines.Hugo Reid (1811–1852), born in Scotland, was an early resident of Los Angeles County who became a naturalized citizen of California (then a part of Mexico) in 1839. He married Barolomea, a respected Gabrieleño woman, who became known as Victoria Reid. Born at the village of Comicranga and taken to San Gabriel Mission at the age of six, Bartolomea was married at the age of 13 to an older indigenous man, as arranged by the Franciscan fathers. The couple later were given small plots of land for their work at the mission.
When the mission was secularized, Bartolomea had been widowed and had remarried, to Hugo Reid. As he was not yet a naturalized citizen, she received a land grant in her name alone. Their marriage elevated Hugo's status, as she was a well-connected mission Indian.Elias Jackson “Lucky” Baldwin purchased Rancho Santa Anita in 1875. In 1879 Baldwin added a wooden wing to the old adobe home. Elias Jackson "Lucky" Baldwin (1828–1909) was a pioneer of California business, an investor, and real estate speculator during the second half of the 19th century. He earned the nickname "Lucky" Baldwin due to his extraordinary good fortune in a number of business deals. He built the luxury Baldwin Hotel and Theatre in San Francisco and bought vast tracts of land in Southern California, where a number of places and neighborhoods are named after him.In 1947 the state and county acquired the land to create an arboretum around the lake and historic Reid-Baldwin structures.
