It's fun to discover the origins of words we use everyday. Many words were once either someone's name or a product name, or even a place name. I'll preempt Wilsjane and use Thomas Crapper as an example, the man who invented the toilet or WC and knows crap when he sees it! Post up as many words you can think of that were once names and are now generic words. Provide info on the names.
Names of historical groups are ok too like the Thugs and Vandals. Thugs: One of a group of professional criminals, devotees of Kali, who robbed and murdered travelers in northern India until the mid-1800s. Vandals: the Vandals were a Germanic people who plundered Rome for fourteen days,[3] Renaissance and early-modern writers characterized the Vandals as prototypical barbarians. This led to the use of the term "vandalism" to describe any pointless destruction, particularly the "barbarian" defacing of artwork.
How about the word 'assassin?' From Wikipedia: "A member of a militant subgroup of Ismailis that in the 11th, 12th, and 13th centuries carried out political assassinations directed especially against Seljuk rule."
How about John Q. Public? "No one knows what the Q in John Q Public actually means, due to the fact that the initial doesn’t really stand for anything. When the name began being used to refer to the collective public (in the early 20th century) we would occasionally find letters other than Q. stuck between the John and the Public." ~Wikipedia
Many places names have become generic for various things, esp. things like wine. Champagne was becoming a generic term meaning almost any bubbly wine. It's a specific grape growing region in France and they insist the appellation can only apply to wines with grapes grown in Champagne and processed using the traditional hand turn method. So they require the entire world to comply or lawsuits will follow.

Yes it's a UNESCO thing regarding produce of protected origin. Melton Mowbray pork pies is another as is the 'Cornish Pasty'. They can be made elsewhere but can't be called those names unless they are compliant with the UNESCO rule. I think sherry is another.
Nobody mentioned Hoover. The generic name for a vacuum cleaner. No it's not Dyson. Lol And Google, pretty much. Not someone's name but the word used instead of 'search'.
Surprisingly, the 2 meanings of the word Turkey seem to be coincidental, but they're not. A similar guinea fowl was imported to England, and it came thru the ottoman empire, or Turkey. It was applied when the similar bird appeared in markets.
What about a trump?! Long before 2016, in the UK, England mostly, when someone farted it was described as trumping. It was just meant to be. Today we have a Trump trumping from his mouth.
In UK, peelers. And bobbies. Not people removing the skin of potatoes or floating somewhere but, police officers, named after the founder of the police, Sir Robert Peel.
