Brosl Hasslacher

Brosl Hasslacher (May 13, 1941 – November 11, 2005) was a theoretical physicist.

Brosl Hasslacher obtained a bachelor's in physics from Harvard University in 1962. He did his Ph.D. with D.Z. Freeman and C.N. Yang at the State University of New York at Stony Brook. After having several postdoctoral and research positions at Institute for Advanced Study in Princeton, New Jersey, Caltech, ENS in Paris, and CERN, he settled for more than twenty years at the Theoretical Division of the Los Alamos National Laboratory. There he was involved in theoretical, experimental, and numerical work in theoretical physics, high-energy physics, nonlinear dynamics, fluid dynamics, nanotechnology, and robotics.

In the 1970s, he worked on the extended hadron model, collaborating with A. Neveu.

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.

In the 1990s, Hasslacher worked with Mark Tilden on several papers concerning Biomorphic engineering. He is largely credited for using nonlinear dynamics to describe and design Tilden's BEAM robotics.

In 1994, Hasslacher's UNIX account (bhass) at Los Alamos National Laboratory was used by hacker Kevin Mitnick to break into computer security expert Tsutomu Shimomura's computers.

He retired from Los Alamos National Laboratory in 2003.
