Given the question: Information: - The Oceanic Steam Navigation Company or White Star Line of Boston Packers, more commonly known as just White Star Line, was a prominent British shipping company. Founded in 1845, the line operated a fleet of clipper ships that sailed between Britain and Australia. Today it is most famous for their innovative vessel "Oceanic" of 1870, and the Olympic class ocean liners, including the ill-fated RMS "Titanic". - The American Line was a shipping company founded in 1871 and based in Philadelphia. It began as part of the Pennsylvania Railroad, although the railroad got out of the shipping business soon after founding the company. In 1902, it became part of the International Navigation Co., with the American Line generally handling traffic between the United States ports of Philadelphia and New York City and the British ports of Liverpool and Southampton. Sister company Red Star Line handled traffic between America and the European continent, primarily through Antwerp, Belgium. The company's most prominent president was Clement Griscom, who led the company from 1888 to 1902 and worked as a company executive for its entire existence. During its existence, the company was the largest American shipping company, rivalled only by the smaller, Baltimore-based Atlantic Transport Lines, although this distinction is a marginal one, as all American oceanic shipping concerns were dwarfed by British companies such as the White Star Line or Cunard Line and German ones such as HAPAG. - City of Brussels was a British passenger liner that set the record for the fastest Atlantic eastbound voyage in 1869 , becoming the first record breaker driven by a screw . Built by Tod and Macgregor , she served the Inman Line until 1883 when she sank with the loss of ten people after a collision while entering the Mersey . - Cunard Line is an Anglo-American cruise line based at Carnival House at Southampton, England, operated by Carnival UK and owned by Carnival Corporation & plc. It has been a leading operator of passenger ships on the North Atlantic, celebrating 175 years of operation in 2015. '' - The Inman Line was one of the three largest 19th-century British passenger shipping companies on the North Atlantic, along with the White Star Line and Cunard Line. Founded in 1850, it was absorbed in 1893 into American Line. The firm's formal name for much of its history was the Liverpool, Philadelphia and New York Steamship Company, but it was also variously known as the Liverpool and Philadelphia Steamship Company, as Inman Steamship Company, Limited, and, in the last few years before absorption, as the Inman and International Steamship Company.
