This chapter tackles John Radclyffe Hall and the sexologists’ “invert” as the next archetype. Hall was part of a subculture of “inverts” and their “wives” at a time when sexological theories were becoming familiar to the public. Despite the sexologists’ attempts to identify a unified theory of inversion, there were different models of female masculinity prevalent in same-sex circles. Female inversion (usually accompanied by homosexuality) was the model applied to women similar to Anne Lister: ones with a masculine identification and performance, who desired non-masculine women.
