The Academy's first official museum opened in 1874 at the corner of California and Dupont Streets (now Grant Avenue) in what is now Chinatown, and drew up to 80,000 visitors a year.[citation needed] To accommodate its increasing popularity, the Academy moved to a new and larger building on Market Street in 1891, funded by the legacy of James Lick, a 19th-century San Francisco real estate mogul, entrepreneur, and philanthropist.[citation needed] Only fifteen years later, however, the Market Street facility fell victim to the 1906 San Francisco earthquake and three days of fire, which also wiped out all but a wheelbarrow full of the Academy's library and specimen collections.[citation needed] In the widespread destruction occurring in the aftermath of the quake, Academy curators and staffers only were able to retrieve a single cart of materials, including Academy minute books, membership records, and 2,000 type specimens.[citation needed] Fortunately, the 1905-1906 scientific collecting expedition to the Galápagos Islands (the first of several sponsored by the academy to the archipelago) already was underway, and it returned seven months later, providing replacement collections for those lost.[16][17]
