I came across this guide (dated 2025) a couple years ago and thought it was interesting. Not a quant or even in finance though, so I don’t know how accurate it is:

Don't think it's a guide like "Hey here's how YOU can BECOME A QUANT!" bs, more about the stories/history of 25 different quants. So more of a personal story/history doc. I think it's an interesting read if you are a finance nerd

Should be added to the title.....

yeah, nearly 20 years :-D

Year added above. Thanks!
