Thomas Dam (May 15, 1915 – November 12, 1989) was a Danish woodworker and fisherman who designed and invented the original troll doll also known as the "Good Luck Troll". He created the toy during a period of financial distress, and carved it from wood. Soon, the family had started up a new business and Dam earned enough to buy himself a small factory where the dolls were produced in plastic. Dam created many different trolls as well as plastic baby dolls.
