Career
Marcus was probably born in 1749 in Schwaan, Germany. Marcus"s considerable impact on the history of Norrköping and his significance to immigration and advancement have been pointed out in several publications. He had that city"s first synagogue built, which opened in 1796 for the increasing community centered on its congregation.
That and his general benefit to Sweden, as a merchant especially privileged by King Gustav III, and his position as an East Gothland property owner and community leader, have been recorded in published biographical articles
Marcus died 13 March 1819 in Norrköping, Sweden. Two of Marcus"s daughters, Lowisa (1787-1842) and Hedda (1796-1834) married two brothers of the successful von Reis family of Gothenburg Jews.
In 1900, a comprehensive account of the entire Marcus family and its descendants was published in Sweden as a large printed circular chart, and an extensive family roster was updated until 1942 by Curt Marcus. Beginning around that time, Jewish descent (no matter how diluted) was kept in low profile, especially during World World War II, despite Sweden"s neutrality.
