Egil A. Hylleraas (1898–1965) — a pioneer of computational quantum mechanics

Hylleraas’ work on the helium atom in the 1920s confirmed the validity of quantum mechanics for many-particle systems and probably represents the first important use of computing in physics. Today, Hylleraas’ method is routinely used for high-accuracy simulations of molecules in chemistry.  

Short Biography of Hylleraas

Egil Andersen, the youngest of ten siblings, was born in 1898 in Hylleråsen, a small village near the Swedish border, 25 miles north of Trysil. 

Scientific Contributions of Hylleraas

In 1929, Hylleraas invented a method that gives an accurate description of the relative motion of electrons in atoms and molecules. 

Hylleraas Exhibition at the CTCC

The Centre for Computational and Theoretical Chemistry (CTCC) has prepared a small exhibition about Hylleraas and his contributions to physics and chemistry

Pictures from the life of Hylleraas


We would like to express our heartfelt thanks to Inger Hylleraas Bø for kindly providing us with photos, books, and the desktop computer.

The exhibition was designed and prepared by Chloé Turlotte,  Ellen Christina Sjøwall and Trygve Helgaker with help from Jan Ingar Johnsen.
