It is regrettable that the case of Dr. Mary Walker, late of New York State, seems never, so far as I am aware, to have been investigated by any competent medico-psychologist; as I feel certain it would have afforded some enlightenment in this interesting field of research. The, in many respects, parallel case of "Murray Hall," who died in New York city in 1901, is mentioned by Ellis,* whose omission of the Walker case is more easily accounted for by his foreign residence, than it is with such investigators as Lydston and Kiernan, who contributed so largely to the study of American cases of inversion.
Murray Hall's real name was Mary Anderson, born at Govan, Scotland. Left an orphan at an early age, she went to Edinburgh, where she worked for some time as a man. The discovery of her sex, through illness, caused her to emigrate to the United States, where she lived as a man for thirty years, becoming somewhat notorious as a Tammany politician, in New York, as well as a rather riotous "man about town."
She seems to have associated much with girls, being exceedingly jealous of them; was slight in build, with a squeaky voice, and habits and manners essentially masculine. Her first marriage ended in separation; but the second, which lasted twenty years, was only terminated by the death of the "wife." She smoked, chewed tobacco, drank, and could sing a ribald song with the best, or worst, of them; wore baggy trousers to conceal her sex, and finally died of mammary carcinoma, in 1901.
