This was replaced in 1900 by a separate building on the outer quadrangle, named the Thomas Welton Stanford Library after its major donor, Leland Stanford's younger brother. This library was soon recognized as being too small, and a new larger library in a separate building was begun; however, it was destroyed in the 1906 San Francisco earthquake before it could be completed.[2]
