stood on the steps of the UIW office building on 20th Street during the auction. At this point, he was the only bidder. Schwab was widely believed to have engineered the demise of the U.S. Shipbuilding Corporation in order to gain control of the industry. Whether or not that was true, he certainly benefited from the collapse of the US Shipbuilding combine. At the time of the 1906 San Francisco earthquake, the coastal passenger liner of the San Francisco and Portland Steamship Company had been undergoing a refit at the yard's hydraulic drydock. The earthquake caused the iron-hulled Columbia to shift off her supports and roll onto the drydock on her starboard side. This damaged the drydock, a key feature of the yard, beyond economic repair. Columbia on the other hand, despite being partially flooded and damaged, was repaired and returned to service in January 1907. In 1908, Bethlehem Shipbuilding Corporation bought the Hunter's Point drydocks. In the pre-World War I era, Union Iron Works built several navy ships that became internationally famous due to the Spanish–American War including Commodore Dewey's flagship the Olympia. After 1905, the shipyard operated as part of Bethlehem Steel, and produced both warships and merchant ships. The shipyard was expanded in 1911 by purchasing Risdon Iron Works, the land next to the shipyard. Risdon Iron Works built locomotives, this was closed and a new shipyard was built to build US Navy including destroyers and submarines. Risdon Iron Works was founded by John Risdon of Saline, Michigan in 1896. Risdon Iron Works started by building boilers, iron pipes, steam engines and gas engines. From 1873 to 1909 Risdon Iron Works also built ships, tugs, ferries and barges. John Risdon held the patents for the first river mining dredge.
