Christina Nyman known as Madam Nyman (1719–1795) was a Swedish brewer. She was a major figure in contemporary Stockholm business life and known as a benefactor of culture. She is perhaps most known for establishing the Stenborg Theatre in partnership with Carl Stenborg (1784).[1] She, as well as her brothers and nephews, belonged to the political allies of king Gustav III of Sweden among the merchant class, and he reportedly treated her as a valuable partner.
