When my nephew Benjamin was learning to speak he couldn’t pronounce my name (Gareth) properly. Instead he used to call me “Geigy” (pronounced Guy-ghee).
While I was lurking in some corner of the University a couple of months ago I came across this book: Geigy Scientific Tables, Seventh Edition.
Yay! It’s my nephew’s made-up name for me. I’m famous … sort of.
