Aneesur Rahman (24 August 1927 – 6 June 1987) pioneered the application of computational methods to physical systems. His 1964 paper on liquid argon studied a system of 864
argon Argon is a chemical element with the symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas. Argon is the third-most abundant gas in Earth's atmosphere, at 0.934% (9340 ppmv). It is more than twice as abu ...

, which he invented with David J E Callaway. Aneesur Rahman was a native of Hyderabad, India. He earned his undergraduate degree in physics and mathematics from Cambridge University in England and his Ph.D. in theoretical physics from Louvain University in Belgium. In 1960, Dr. Rahman began a 25-year tenure as a physicist at the Argonne National Laboratory (Argonne, Ill.) (operated by the

molecular dynamics Molecular dynamics (MD) is a computer simulation method for analyzing the physical movements of atoms and molecules. The atoms and molecules are allowed to interact for a fixed period of time, giving a view of the dynamic "evolution" of the s ...
, a discipline of physics that utilizes computers to simulate microscopic behavior of physical systems. In 1977 Dr. Rahman was awarded the Irving Langmuir Prize by the American Physical Society. Enrico Fermi's Group (at Los Alamos during the 1950s), George Vineyard's group (radiation damage studies at Brookhaven in 1960), as well as Tom Wainwright and Berni Alder's group (at the Livermore Radiation Laboratory in the 1950s) developed generalized leapfrog and event-driven molecular dynamics algorithms a bit earlier than Rahman. Berni Alder received a National Medal of Science award from President Obama in 2009. The
