The Swinging Cabin of SS Bessemer

English inventor Sir Henry Bessemer, renowned for his groundbreaking steel manufacturing process that still bears his name, once lamented, “Few persons have suffered more severely than I have from sea sickness.” Despite being one of the foremost inventors of the Second Industrial Revolution, Bessemer's brilliance was not immune to personal trials. With over a hundred inventions in iron, steel, and glass to his name, most of which saw success, his endeavor to create a ship to alleviate his chronic seasickness, however, ended in failure. After a particularly harrowing journey from Calais to Dover in 1868, during which time Bessemer was virtually incapacitated by seasickness, the inventor resolved to build a ship where the passenger cabin would remain unaffected by the vessel's rolling and pitching at sea. In order to achieve this, Bessemer devised a pioneering solution: suspending the cabin, dubbed the Saloon, on gimbals and mechanically maintaining its horizontal position using an intricate system of hydraulic cylinders. However, unlike modern stabilization systems equipped with automatic feedback mechanisms, Bessemer's design relied on a steersman to manually control the hydraulics while monitoring a spirit level. After conducting successful trials with a scale model at Denmark Hill, Bessemer established the Bessemer Saloon Ship Company, a limited joint stock company tasked with operating steamships between England and France. Securing £250,000 in capital, the company financed the construction of the SS Bessemer, enlisting the renowned naval constructor Edward James Reed as its chief designer. The steamship Bessemer measured 350 feet in length and 40 feet in width at the deck, with propulsion provided by two pairs of paddle wheels. Its internal Saloon, a spacious chamber stretching 70 feet in length, 30 feet in width, and with a ceiling soaring 20 feet high from the floor, was a testament to opulence.
