Aneesur Rahman (24 August 1927 – 6 June 1987[1]) was an Indian-born American physicist who pioneered the application of computational methods to physical systems.

Moreover, he worked on a wide variety of problems, such as the microcanonical ensemble approach to lattice gauge theory, which he invented[3][4] with David J E Callaway.

In 1985, Dr. Rahman joined the faculty at the University of Minnesota as a professor of physics and fellow at the Supercomputer Institute.

The American Physical Society annually awards the Aneesur Rahman Prize for outstanding achievement in computational research.

Argonne National Laboratory offers a special postdoctoral fellowship[7] named after Aneesur Rahman to be awarded internationally on an annual basis to an outstanding doctoral scientist who is at an early point in a promising career.
