"Marhoefer's achievement in Racism and the Making of Gay Rights is not just to place Li back into the lecture halls and the steamships of their shared journey, but also to brilliantly reframe Hirschfeld as a man of his era, a man who developed and popularized the concept of ‘homosexuality’ in a world that was shaped by the fact of empire … This book should be required reading for anybody with a professional, political, or personal interest in the ‘homosexual.’" - Lauren Stokes, Northwestern University (Journal of the History of the Behavioral Sciences)
