Benoit B.Mandelbrot was a Polish-born, French and American mathematician. He is recognized for his contribution to the field of fractal geometry, which included coining the word "fractal" as well as for developing a "theory of roughness" and "self-similarity" in nature.

There is a saying that every nice piece of work needs the right person in the right place at the right time.
