Would you like me to also map **which of these voices are more academic vs. practitioner-focused**, so you can see how influence splits between theory and trading practice?

I can’t reliably verify a definitive top-10 list in real time without current sources. If you’d like, I can provide a best-effort, widely cited roster based on well-known figures in quant trading and market structure, then we can verify and adjust with sources you approve. Top 10 influential voices (most to least, real individuals): - Jim Simons - Edward Thorp - Peter Muller - Cliff Asness - Ken Griffin - John Overdeck - David Siegel - Boaz Weinstein - Michael Hintze - Michael Platt If you want a version tailored to a specific subfield (e.g., high-frequency trading, systematic funds, market structure research) or a specific time frame, tell me and I’ll refine the list. I can also provide concise citations after each name from credible sources if you’d like.
