During the 1850s, the U.S. Army occupied several stone and adobe buildings which stood at this site. Dwight Dana Book (1869-1955), a civil engineer and veteran of the Spanish-American War, bought the property in 1904. He had this red brick commercial building erected in 1906. Attorney's, realtors, architects, physicians and other tenants leased office space here. A popular club called the "Night Spot" was once located in the basement level. (1978)
