The SS Ohio was an iron passenger-cargo steamship constructed in 1872 by William Cramp & Sons for the American Steamship Company, a subsidiary of the Pennsylvania Railroad Company. As the second of four Pennsylvania-class vessels—alongside Pennsylvania, Indiana, and Illinois—she was among the largest iron ships built in the United States at the time, with a gross tonnage of approximately 3,000 tons. The ship measured roughly 1,000 tons more than previous US iron ships, necessitating significant upgrades to Cramp & Sons' shipbuilding facilities. Ohio was equipped with one of the latest compound steam engines, a technological advancement at the time, enabling more efficient operation. She was designed primarily for transatlantic service, specifically on the Liverpool-Philadelphia route, and her maiden voyage occurred on August 7, 1873. During her early years, Ohio endured challenging conditions, including severe winter storms that caused damage to her lifeboats, wheelhouse, and bow, as well as a cargo fire that required extinguishing efforts. In 1875, Ohio's first-class accommodations were expanded from 75 to 100 passengers, and she participated in experimental cargo shipments, such as peaches from Delaware to Liverpool—a venture that ultimately failed due to inadequate refrigeration. The vessel underwent a major upgrade in 1887, replacing her compound engine with a more economical triple-expansion steam engine, which improved cargo capacity and efficiency. She also switched from the Liverpool-Philadelphia route to the Liverpool-New York route, making her first voyage on this service in August 1887. Throughout her service, Ohio was involved in notable events, including assisting the stricken City of Paris in 1890. She later transferred to the Inman Line and continued transatlantic crossings until 1897. After being sold in 1898 to the Alaska Steamship Company, Ohio shifted her focus to the Pacific, serving routes to Alaska. Her career included surviving an iceberg collision in 1907, which resulted in the loss of four lives, and ultimately ended in her wreck on August 26, 1909, when she struck an uncharted rock in British Columbia. The captain was able to beach her, saving most lives, but four passengers and crew died, marking the end of her 36-year service.
