English sexologist Havelock Ellis wrote the first objective scientific study of homosexuality in 1897, in which he treated it as a neutral sexual condition. Called "Sexual Inversion" it was first printed in German and then translated into English a year later. In the book, Ellis argued that same-sex relationships could not be characterized as a pathology or a crime and that its importance rose above the arbitrary restrictions imposed by society. He also studied what he called 'inter-generational relationships' and that these also broke societal taboos on age difference in sexual relationships. The book was so controversial at the time that one bookseller was charged in court for holding copies of the work. It is claimed that Ellis coined the term 'homosexual', but in fact he disliked the word due to its conflation of Greek and Latin.
