In 1893, Weber married his distant cousin Marianne Schnitger, later a feminist activist and author in her own right,[3][36] who was instrumental in collecting and publishing Weber's journal articles as books after his death, while her biography of him is an important source for understanding Weber's life.[37][38] They would have no children.[32] The marriage granted long-awaited financial independence to Weber, allowing him to finally leave his parents' household.[23]
