Alexander Dalgarno was born in London in 1928, and spent his childhood there. He was educated in mathematics and atomic physics at University College, London, earning a Ph.D. in theoretical physics in 1951. He was an academic at the Queen's University, Belfast from 1951 to 1967 where he worked with Sir David Bates and rose from assistant lecturer to professor. In the 1950s, he laid the foundations for long-range atomic interaction studies which are of critical importance for today's interest in Bose–Einstein condensates.
In 1967 he moved to Harvard to join their department of astronomy and held the positions of acting director of Harvard College Observatory, chairman of the department of astronomy, associate director of the Harvard-Smithsonian Center for Astrophysics and director of the Institute for Theoretical Atomic and Molecular Physics. Dalgarno's research covered three main areas: theoretical atomic and molecular physics, astrophysics and aeronomy (the study of the upper atmosphere). He made contributions in theoretical chemistry, scattering theory, atmospheric physics & chemistry and astrophysics and was the author of more than 600 publications. Sir David Bates wrote in 1988 that "There is no greater figure than Alex in the history of atomic physics and its applications." Known as the "father of molecular astrophysics", Dalgarno was also a physicist at the Smithsonian Astrophysical Observatory and was formerly the editor of the Astrophysical Journal Letters.
He married Barbara Kane, from whom he was later divorced, and had four children.
His work was recognized by many awards, including the prize of the International Academy of Quantum Molecular Science, the Davisson-Germer Prize of the American Physical Society (1980), the William F. Meggers Award of the Optical Society of America (1986), the Gold Medal of the Royal Astronomical Society (1986) and the Benjamin Franklin Medal in Physics from the Franklin Institute (2013).
He was a Fellow of the American Geophysical Union and the American Physical Society and a member of the U.S. National Academy of Sciences. He was elected a Fellow of the Royal Society in 1972 and awarded their prestigious Hughes Medal in 2002. He was also a member of the International Academy of Quantum Molecular Science.
In 1998, Asteroid 6941 was named Asteroid Dalgarno.
