Thingvalla line was a shipping company founded by Danish financier, industrialist and philanthropist Carl Frederik Tietgen in 1879 in Copenhagen, Denmark. It maintained a route between Copenhagen and New York City calling at Kristiania (present day Oslo) and Kristiansand on the way. At its peak, it had ten ships in its fleet. In 1898, the company was bought by DFDS, another Danish shipping company, and the name was changed to Scandinavian America Line. [1]
