His brother Jonathan-Raphaël created a branch in Antwerp in 1827 before settling in Brussels in 1836. Having married Henriette Goldschmidt, the daughter of Frankfurt banker Hayum-Salomon Goldschmidt, Louis-Raphaël Bischoffsheim established the Bischoffsheim, Goldschmidt & Cie bank in Paris in 1846, then in London in 1860. In 1863 he merged these banks with the Banque de Crédit et de Dépôt des Pays-Bas, which he had founded in Amsterdam: the Bischoffsheim family thereby established a powerful multinational banking conglomerate.[1][2]
