Sex Researchers:

Ulrichs was a researcher whose ideas were ahead of his time. Even though his ideas lost support in the 1860's they are now being explored again. Ulrichs was a homosexual in the 1800's (Kennedy, 1980). He theorized that homosexuality was innate and that its origination could be located in an area of the brain (Kennedy, 1980; & Money, 2003). He believed that such behavior was not deviant but biologically driven in certain individuals.
