Berni Julian Alder
University of California at Davis
Doctoral advisorJohn Gamble Kirkwood

Berni Julian Alder (September 9, 1925 – September 7, 2020) was a German-born American physicist specialized in statistical mechanics, and a pioneer of computational modelling of matter.[3]

Biography

Alder was born in

University of California at Berkeley and a master's degree in chemical engineering from the same institution in 1947. He went to the California Institute of Technology[4] to study under John Gamble Kirkwood for his PhD in 1948 and worked for the investigation of phase transitions in hard-sphere gas with Stan Frankel, where he got the idea to use the Monte Carlo method. After he finished at Caltech in 1952, he went to Berkeley and worked part-time at Berkeley to teach chemistry and part-time as a consultant under the suggestion of Edward Teller in the nuclear weapons program for the Lawrence Livermore National Laboratory to help with the equations of state. In collaboration with Thomas Everett Wainwright, and Mary Ann Mansigh, he developed techniques for molecular dynamics simulation in the mid-1950s,[5] including the liquid-solid phase transition for hard sphere[6] and the velocity autocorrelations function decay in liquids.[7][8] In the late 1950s, together, they began conducting computer simulations of idealized molecular dynamics of 2D hard spheres to investigate transitions between solids, liquids and gasses. In 1967 they observed long-time tails not expected from existing calculations, and although it was realized that these were a consequence of fluid-like behavior not readily accounted for in purely microscopic approximations, it did not seem plausible that large-scale fluid phenomena could be investigated with molecular dynamics.[9]

Alder, along with Teller, was one of the founders of the

University of California at Davis
, and later professor emeritus.

In 2001, he was awarded the Boltzmann Medal for inventing technique of molecular dynamics simulation.

He was elected a Fellow of the American Academy of Arts and Sciences in 2008.[11] In 2009, he was awarded the National Medal of Science.[12]

Alder was a Guggenheim Fellow. He was the editor of the book series Methods in Computational Physics and the founder of the magazine Computing.

Alder died September 9th, 2020, of heart failure and COVID-19 related complications. He passed in the company of loved ones.[2]
