Thomas Fredrik Olsen or Fred Olsen (born 1 January 1929) is a Norwegian shipping magnate and Chairman of the companies in the Fred. Olsen Group. He is the fourth generation running the Fred. Olsen Group, founded by his great grandfather Petter Olsen and named after his grandfather Thomas Fredrik Olsen. Though he remains the chairman of the companies, ownership and CEO functions are retained by his daughter Anette S. Olsen. In addition to his jobs within the Fred. Olsen group he was for a period also chairman of the Aker Group.
Fred. Olsen has been called "The Norwegian Howard Hughes" for his great wealth and avoidance of publicity; although a recluse he is also reputed to be the inspiration for the look of The Simpsons cartoon character Mr. Burns.
It was announced on 3 January 2006, that Fred Olsen was to sell almost his entire collection of Edvard Munch paintings; the auction through Sotheby's London fetched almost £17m. Olsen has previously been involved in a legal dispute with his brother, Petter Olsen, concerning the important Munch collection brought together by their father Thomas Fredrik Olsen; according to the will of their mother Henriette Olsen, they were to be left to the younger son. Fred Olsen contested the will but lost the case in the Oslo District Court in 2001.
