EPONYMS

Would you trust a Quisling or a Judas Iscariot?

And why do we say "Quisling" and "Judas Iscariot", but neither "Pettigrew" nor "Greyjoy"?
(Simply, because these two characters are very recent.)

A Venus is a hottie, but Venus (the planet) is hot in another sense, and a Venus (as a razor) is rather on the cold steel end of the spectrum.

And there are some animal species called Goliath: the Goliath frog, the Goliath beetle, the Goliath spider... How many Goliath beetles can a Goliath spider eat in a day? And a Goliath frog?

Adelie penguins, the brand Ford, Mitsubishi, Saint Petersburg (once known as Leningrad), more brands like McDonald's, Gustavus Adolphus cakes, peach Melba, Pavlova cakes, pears Belle-Hélène, Przewalski horses, plant genera like Tradescantia, Linnaea, Loeflingia, and Wikstroemia... boycotting, Kobrigrams, cardigans, Wellington boots, Nelson's Column at Trafalgar Square, the name of every other planet and dwarf planet, many other animal and plant species named after their discoverers... the Victoria genus of water-lilies (in the Amazon rainforest), Victoria Falls, Lake Victoria, many communities and regions also called Victoria, the Victoria Cross, Victoria sponge cake, the Victoria and Albert Museum... (Queen Victoria has left a HUGE footprint!), the Philippine Islands, the Cook Islands, Cook Strait, Magellan Strait, both Magellanic Clouds, many other places on Earth and in space named after their discoverers... degrees Celsius, volts, amperes, watts, newtons, pascals, and many other units of measurement, the months of July and August...

Can you think of any more eponyms (in space, animals, plants, places, dishes, brands, expressions, units of measurement... named after famous people or characters associated with them)?
