The SS Pasteur, launched in 1938 and named after the renowned scientist Louis Pasteur, was a significant ocean liner built by Chantiers de l'Atlantique in Saint-Nazaire for the Compagnie de Navigation Sud-Atlantique. Her construction began in 1938, and she was launched on February 15 of that year. Her fitting out was delayed by a fire in March 1939, and she was not completed until August 1939, just prior to the outbreak of World War II. Designed as a smaller but faster replacement for the lost flagship L'Atlantique, Pasteur had a gross register tonnage of 29,253 GRT. She measured 212.4 meters in length and 26.8 meters in beam, with a draught of 9.3 meters. The vessel featured 11 decks and extensive loading facilities, along with a passenger capacity of 751. Powered by four steam turbines offering a maximum output of approximately 50,000 horsepower, she could reach speeds up to 26 knots, although her typical service speed was around 22 knots. Initially laid up in Saint-Nazaire due to the onset of WWII, Pasteur was pressed into military service, serving as a troop transport and hospital ship. She transported approximately 300,000 soldiers and was involved in significant wartime operations, including carrying troops to the Battle of El Alamein, transporting prisoners of war, and participating in troop movements across various theaters. Notably, she made a voyage from Glasgow to Halifax with British troops and carried US and Canadian troops back home after the war, traveling over 370,669 miles during her wartime service. Post-war, Pasteur returned to her owners in France and continued as a troop transporter, notably during the First Indochina War and the Suez Crisis. In 1957, she was sold to North German Lloyd, renamed TS Bremen, and extensively rebuilt. Her tonnage was increased to 32,336 GRT, and her propulsion upgraded to four steam turbines with a maximum output of 60,000 HP, enabling speeds up to 26 knots. She then served as a transatlantic passenger liner and cruise ship, operating routes between Europe, North America, and the Caribbean. Throughout her career, she changed ownership multiple times, served various roles including passenger service, cruising, and accommodation, and was finally sold for scrap in 1980 after sinking en route to shipbreakers. Her long service life and adaptability made her a notable vessel in 20th-century maritime history.
