According to Wikipedia:

The G-spot, also called the Gräfenberg spot (for German gynecologist Ernst Gräfenberg), is characterized as an erogenous area of the vagina that, when stimulated, may lead to strong sexual arousal, powerful orgasms and potential female ejaculation. It is typically reported to be located 5–8 cm (2–3 in) up the front (anterior) vaginal wall between the vaginal opening and the urethra and is a sensitive area that may be part of the female prostate.

We all know the jokes about it and whether we actually found it, either guy or girl.

How about the guy that founded it. The G-spot is named after Ernst. The obvious questions are how did he find it, how long did he search for it and how long did he keep up the research after he completed his studies just to have naked women around. Did he change his name to Eric Stratton, rush chairman, Delta Tau Chi?

So he is famous for having the pleasure spot named after him. The difference in founded it and found it.
