Gynecologist Dr. Ernst
Gräfenberg came to the US from Nazi Germany in 1940. He ran a
successful gynecology practice in New York until his death in 1957.
Gräfenberg researched the subject of stimulation and stated in a
study, ”An erotic zone always could be demonstrated. . ." Although
others had studied this before him, he is usually given credit for its 'discovery' and the name “G-spot”
named for him came from a 1981 paper published in the Journal of Sex
Research.
He also invented the first known Ring IUD birth control device, the
Gräfenberg ring.
