I came to know of this guy though Jim Simons.

He once "leaked" the idea that Jim Simon's trading success came from his use of ideas called "gauge theory" and "fibre bundles".

I forgot the exact timestamp, but you will have to watch the entire interview to find that segment — https://youtu.be/zVWlapujbfo

Simons himself completely disspells this idea in his interview on Numberphile.

AFAIK, one of the early hires at RenTech was Leonard Baum, famous for the Baum–Welch Algorithm.
RenTech is quite secretive, but this supports the rumors that simple graphical models for time series were behind some of their trading strategies.

  Two other data points for this are
  Brown and Mercer (who became ideologically opposed co-CEOs)

It's a trivial statement since many equities are correlated on a multidimensional manifold of characteristics. Jim Simons was just early and now rentech is nothing special.

Rentec is still world renowned after pioneering the quant business 40+ years ago. I don't think the rested on their laurels with some easy thing that they just stumbled on early

This reads like “Newton or Einstein were just early”. That’s the whole thing, being the first person to do it.
