Erotomania is also called de Clérambault's syndrome, after the French psychiatrist Gaëtan Gatian de Clérambault (1872–1934), who published a comprehensive review paper on the subject (Les Psychoses Passionelles) in 1921.
Charles Robert Ashbee, son of erotomaniac Henry Spencer Ashbee, created his Guild of Handicraft whilst a resident at Toynbee Hall in the late 1880s
