His daughter, Elise MIMEUR, soon married the young Charles BADER, from a Santenay winemaker family. Together, they developed the Maison BADER-MIMEUR, selling the estate's wines as well as developing a major trading business. The wines were mainly sold at the Halle aux Vins in Paris and in their cellar shop, in rue Saint Dominique. In the same time, the estate bought several plots of vines in Chassagne and Saint-Aubin.
From the 1950s, their son, Pierre BADER, joined the family business and continued to develop the business activities, from Paris where he lived.
