Max and his younger brother David owned a linen wholesale business in Stuttgart. They got the capital to open this business from their older brothers Seligmann and Sigmund, who brought the money back from the USA.
“Ten thousand guilders were used for Max and David Heilner and their ‘Heilner Brothers’ linen wholesale business in Stuttgart, and further funds were used to finance the purchase of a new house in Karbach by the Gutmann family. In 1864 Aron Heilner ended his career as a teacher in Urspringen, moved to Stuttgart with his family and worked in his sons’ business as a bookkeeper. The brother ran the linen business jointly from 1863 to 1896, and then David became the sole proprietor from 1897 onwards. In 1899 he devoted his attention to the newly-founded linoleum factory in Bietigheim, and under his management the “Germania Linoleum-Werke AG” became a successful enterprise. It formed the basis for the “Deutsche Linoleumwerke”, founded in 1926 by David’s son Richard Heilner (1876-1963). Dr. Richard Heilner had his company “arianized” by the Nazis, and was deported to Theresienstadt in 1942. Fortunately, he survived, and returned to Stuttgart.” -“The Heilner Brothers from Urspringen” by Leonhard Scherg
