Friedrich Paulsen was born in the tiny port hamlet of Dagebüll on the North Frisian coast.
[1] In 1933 during his studies in Kiel, Paulsen suffered harassment and threats from National Socialists due to his political beliefs.
In Sweden, whose citizen he became in 1941, he laid the foundation for the establishment of FERRING (1950) by his research on hormones and their synthentical production.
[3][4] After his withdrawal from the company's management he retired to Alkersum, Föhr with his second wife, Dr. Eva Wolf Frandsen.
His youngest son, Frederik Paulsen Jr, is the current chairman of Ferring Pharmaceuticals.
