Juan Bandini (1800 – November 4, 1859) was a Peruvian-born Californio public figure, politician, and ranchero. He is best known for his role in the development of San Diego in the mid-19th century. Early history Bandini was born in 1800 in Lima, Peru to José Bandini, a Spanish sea captain. His father came to California in 1819 and in 1821 participated in the Mexican War of Independence. After the revolution, his father's family moved to San Diego, arriving on September 1, 1834, on the brig Natalie. Marriage and family Bandini married Marie de los Dolores Estudillo on November 20, 1822. She was born c. 1808, daughter of Captain José María Estudillo. They had three daughters, Arcadia, Ysidora, and Josefa, and two sons, Juanito and one who died in childhood. Bandini's second wife was Refugia Argüello, daughter of Santiago Argüello. They had three sons, Juan de la Cruz, Alfredo, and Arturo, and two daughters, Dolores and Victoria. Bandini built a large U-shaped house, Casa de Bandini, in 1829. Initially it had 12 rooms and was one-story. Bandini was forced to sell his house in 1859 due to financial losses. Part of the building was converted into a store. His house was later converted to the Cosmopolitan Hotel in 1869, with a second story and wraparound porch added. The house still stands in Old Town San Diego, at the east corner of the town square, and has recently been fully remodeled and reopened as a hotel and restaurant. Originally the house and hotel were not stuccoed—that was added in modern times to make it look "Spanish Colonial". Civic life Bandini served various public offices such as member of the assembly, sub-comisario of revenues, and substitute congressman. Rancho Jurupa Bandini was granted and occupied Rancho Tecate in 1836. However he was soon driven to abandon it by raids to plunder the ranchos around San Diego by bands of fugitive neophytes, rancho employees, and natives from the interior in 1836-1837. This is now the town of Tecate. In 1838, the Mexican government granted him Rancho Jurupa in modern-day San Bernardino County and Riverside County. During the Mexican–American War, Bandini supported the Americans. With Santiago Arguello he issued an appeal to not resist the Americans. After the war, Bandini was increasingly critical of the U.S. government, especially the Land Act of 1851 that allowed Mexican land grants to be challenged. The Treaty of Guadalupe Hidalgo
