Brosl Hasslacher was born in New York City in 1941 and obtained a bachelor's in physics from Harvard University in 1962.
After having several postdoctoral and research positions at Institute for Advanced Study in Princeton, New Jersey, Caltech, ENS in Paris, and CERN,[1] he settled for more than twenty years at the Theoretical Division of the Los Alamos National Laboratory.
During the 1980s, Hasslacher pioneered with Uriel Frisch and Yves Pomeau the lattice-gas method for discrete simulation of fluid flow.
As part of the Los Alamos National Laboratory's Center for Nonlinear Studies, Hasslacher worked with Mitchell Feigenbaum and contributed ideas to chaos theory.
He is largely credited for using nonlinear dynamics to describe and design Tilden's BEAM robotics.
