The Bethmann family has been remarkable for the high proportion of its male members who succeeded at mercantile or financial endeavors. This family trait began in medieval northern Germany and continued with the Bethmann bank, which Johann Philipp Bethmann (1715–1793) and Simon Moritz Bethmann (1721–1782) founded in 1748 and soon catapulted into the foremost ranks of German and European banks. Even after the bank's sale in 1976, there are Bethmanns engaged in commercial real estate and forestry in the 21st century.
