Lili Ilse Elvenes (born Einar Magnus Andreas Wegener; 28 December 1882 – 13 September 1931), better known as Lili Elbe, was a Danish painter and transgender woman, and among the early recipients of sex reassignment surgery. She was a successful painter under her birth name. After transitioning in 1930, she changed her legal name to Lili Ilse Elvenes and stopped painting; she later adopted the surname Elbe. She died from complications following a uterus transplant. The US and UK English versions of her semi-autobiographical narrative were published posthumously in 1933 under the title Man into Woman: An Authentic Record of a Change of Sex.
