I know there are many products on the market that carry the name of the first one of its kind...Kleenex, Ketchup etc. thanks Bill, I edited my typo

I'm interested in products that have the name of their inventor...eg. it is thought by some that the sandwich got its name from the Earl of Sandwich. This now seems to have been discounted but you get the jist.

Caesarian section seems to be one. Legend has it that Caesar was the first to be born by this method, et voila it now carries his name.

Does anybody have any others?
