The original owner, Alfred "Nobby" Clarke was an Irish sailor boy who arrived in San Francisco in the fall of 1850. He first tried his luck in the gold mines but soon returned to the city, where there was more money to be made as a stevedore. Clarke joined the police force during the Vigilante disturbances of 1856. He resigned from his position as clerk to the Chief of Police in 1887 at which time he is said to have saved some $200,000.
The building became the California General Hospital in 1904 and later a rooming house for employees of Standard Oil. It is presently an apartment house.
