Benoît Mandelbrot

In The Man From The Future, Ananyo Bhattacharya’s biography of John von Neumann, Mandelbrot appears as a firsthand witness to the cost of being an interdisciplinary genius. Having come to the Institute for Advanced Study in 1953 at von Neumann’s own invitation, Mandelbrot recalled that von Neumann was “under extreme pressure” — despised by mathematicians “for no longer being a mathematician,” by physicists “for never having been a real physicist,” and “by everybody for having brought to Princeton this collection of low-class individuals called ‘programmers.’” Kyle’s notes register this observation as a warning rather than mere admiration: the person every field calls on pays a price in belonging to none.

Context: Benoît Mandelbrot (1924–2010) was a Polish-born French-American mathematician best known as the father of fractal geometry — he coined the term “fractal” and discovered the Mandelbrot set, work that gave a mathematical language to roughness and self-similarity in nature, finance, and physics.
