Max was taken out of school in 1910 to work in the family business, where he eventually became a junior manager. During this period he would begin two relationships that would last for the rest of his life. First, he met Friedrich Pollock, who would later become a close academic colleague, and who would remain Max's closest friend. He also met Rose Riekher, his father's personal secretary. Eight years Max's senior, a Christian, and from a lower economic class, Riekher (whom Max called "Maidon") was not considered a suitable match by Moritz Horkheimer. Despite this, Max and Maidon would marry in 1926 and remain together until her death in 1969.
