One of the fathers of the gay rights movement, Ulrichs (1825-1895) penned the highly influential Forschungen über das Rätsel der mannmännlichen Liebe in which he first articulated his view that homosexual love was natural and biological. His subsequent writings have formed the foundation of all later research and his insights were eventually adopted by mainstream science.
Holograph postcard (3" x 5.5") from Ulrichs (signed "Carlo Arrigo Ulrichs") to a bookseller in Emden, Germany regarding his publication Alaudae. Ulrichs has settled in Aquila, Italy towards the end of his life and from 1889 to his death in 1895, he published the literary review Alaudae to promote the international use of Latin. He refers to several subscribers of the journal, including "a bishop and a reigning majesty ...' Although difficult to determine, it appears the card is dated 20 April 1889. Ulrichs correspondence is extremely rare.
