There has been discussion of Max Weber's scholarly connection to Georg Simmel, particularly in terms of their influence on the Frankfurt School, but Marianne Weber too was a colleague of Simmel. In addition to a more than 20 year friendship, in which Max and Simmel conversed and wrote letters often, Weber wrote a critical response to Simmel's 1911 essay ``The Relative and the Absolute in the Problem of the Sexes'', in which she criticized his concept of ``gender relations''.
