Not my words. From a site I found:
"A man famous for a part of the woman's anatomy - Gabriel Fallopius (you can fill in what he is honored for). In the mid 1500's, he designed a medicated sheath to go over the tip of the penis and under the foreskin. It was held on by a pink ribbon so that it would appeal to women.
He was then forced to design one for the circumcised guys - a standard of eight inches (The average man must have been bigger back in those days). It was tested on over 1000 men with overwhelming success.
One would guess that they were trying to prevent pregnancy, but that was the woman's problem in those days. They were actually used to prevent the spread of venereal diseases, syphilis in particular. Men hated them, and gave them the name overcoats.
About 100 years later, England's King Charles II requested his physician, the Earl of Condom, to devise something to protect him from syphilis. He came up with an oiled sheath made from sheep intestine. No one is really sure if he knew about Fallopius' contraption. Soon all the noblemen were using them.
The problem? They reused them (Yuk) without washing them (double Yuk Yuk). Therefore, they still ended up getting that dreaded disease.
The modern rubber was invented in 1870, but was not the thin latex type we see today. Those were developed in the 1930's."
