Ludwig Erdwin Seyler

Ludwig Erdwin Seyler was a Hamburg merchant, merchant banker and politician. He was by marriage a member of the Hanseatic Berenberg dynasty, and was a partner in the Hamburg firm Joh. Berenberg, Gossler & Co. for 48 years (1788–1836), for 46 years as the company's senior partner. The company name was amended in 1791 to reflect him becoming a partner and has remained unchanged since; he "is practically the 'Co.' in the company name." Seyler was one of the first merchants and bankers from modern Germany to establish trade relations with the United States and East Asia. Much of the company's wealth derived from their position as leading sugar importers from the Americas to the North European market, in combination with their activities as merchants bankers. Seyler was one of Hamburg's leading merchants during the Napoleonic Wars and held several political offices. He served as a member of the French-appointed council of Hamburg and after the Napoleonic Wars as the President of the Commercial Deputation, one of the city-state's main political bodies. Ludwig Seyler was a son of the Swiss-born theatre director Abel Seyler and a son-in-law of the bankers Johann Hinrich Gossler and Elisabeth Berenberg through his marriage to their eldest daughter Anna Henriette Gossler.
