Emil Steen (20 February 1870 – 20 July 1915) was a Norwegian businessperson.
He was born in Kristiania[1] as a son of Emil Steen (1829–1884) and a brother of Johan and Christian Steen. His father and two brothers were owners of Steen & Strøm.[2] Emil Steen followed other ventures, however, and became a partner in Nyegaard & Co. around 1900. Founder Morten Nyegaard backed out in 1901, and Steen partnered up with Nyegaard's co-founder Theodor Haslund until Haslund backed out in 1906. Fredrik L. Christensen was then Steen's partner until 1913, when Steen became sole owner.[3] Steen was behind the transformation of the company from a wholesaling company to a manufacturer of pharmaceutical products.[4] The company has since been renamed Nycomed and gone multi-national.
Emil Steen died in July 1915 in Moss.[2] Marshals at his funeral were wholesaler Laurantzon and Halfdan Swensen.[5] After his death, his widow Laura Steen took over the company; in 1921 their son Fredrik Steen took over. He eventually brought in new co-owners.[3] Emil Steen was also an uncle of Erling Steen, who became Steen & Strøm director.[6]
