Spoonerisms, the switching of consonants or morphemes between two words for comic effect; named after William Archibald Spooner, an Oxford Don who dropped many in his speech.
Bowdlerize, for editing a work to remove all the “objectionable” (or “interesting”) bits. Named for Thomas Bowdler, who cleaned up Shakespeare for women and children.
Gerrymandering is named for Gov. Elbridge Gerry of Massachusetts, combined with salamander (which wiggly, slippery critter one of Gov. Gerry’s electoral district re-mappings was said to resemble).
Mentor was the tutor of Odysseus’ son, Telemachus.
We often call someone with a loud voice stentorian. Stentor was the herald of the Greek forces during the Trojan War. He was supposed to have a voice as loud as fifty men shouting.
When you add in the balaclava, which was named not after a person, but after a battle site from the Crimean War, I’m always inclined to refer to that particular conflict as the Sweater War.
The foxtrot takes its name not from its resemblance to the meanderings of a canine, but from vaudeville performer Harry Fox, who invented the dance.
Not a common noun, but also not a trademark: Angel Falls honors no celestial being. Aviator Jimmie Angel, who discovered the falls during a 1933 search for a potentially valuable ore bed, was honored when the English language needed a term for Kerepakupai merú.

Yesterday I saw a shoe shop advertising “plimsoles”. The name “plimsoll” has nothing to do with soles, everything to do with the guy who put loading-lines on the sides of ships, but was not, per Wikipedia, the shoe’s inventor.
Pull a brody or take a brody
It seems more of a New York expression
from the Urban Dictionary
A “Brody” is a miraculous maneuver or stunt.
This comes from “Steve Brody”, the first man to survive the 135 foot jump from the Brooklyn Bridge. In 1885, right after the Brooklyn Bridge was built, Brody bragged he could survive the fall, and did. His amazing survival caused a media sensation, and the phrase “pull a Brody” has been used since then. (Only four people have ever survived the 135 foot drop, which is equivalent to jumping from the top of a fourteen story building.)
In 1885, Steve Brody owned a saloon. Parts of Brody’s saloon still survive today in New York’s Empire Room, which is fitted with mahogany panels and gold leaf plaster impressions recovered from Steve Brody’s Saloon.
The miraculous 1885 survival of Brody made him very famous. From that time to this, New Yorkers have talked about “pulling a Brody” or “taking a Brody”, referring to Brody’s miracle jump and survival.
In 120 years, obviously, some people have forgotten where “pull a brody” came from. Do some research on Steve Brody and you will see this is the actual origin of the phrase
I have to mention a very common word, derived from the name of a man who may have been my ancestor: “guy”, coming from the name of a Guy who tried to blow up the English parliament about 400 years ago.
(My grandfather’s middle name was Fawkes, which supports the family tradition that Guy was up there in the family tree).
