American Line 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.
