Donald Lynden-Bell

Donald Lynden-Bell


Date of Birth
April 5, 1935

Donald Lynden-Bell was educated at the University of Cambridge, where, after postdoctoral periods there and at the California Institute of Technology and the Royal Greenwich Observatory (then at Herstmonceux Castle), he became professor of astrophysics in 1972. He formally retired in 2001 but remained fully active in research until near the end of his life. He was known for significant contributions to the theories of star motions, the formation of the Galaxy, spiral structure in galaxies, chemical evolution of galaxies, and the distributions and motions of galaxies and quasars. He also worked on the mechanisms behind magnetohydrodynamic jets and relativistic disks. His 1962 paper with Olin Eggen and Allan Sandage, proposing that the Galaxy formed in a free-falling collapse, has stimulated an enormous amount of research. In 1969 he proposed that emissions from the centers of nearby galaxies may represent dead quasars. He proposed that quasars are the results of accretion disks around giant black holes in galactic nuclei. He was the senior member and chief theorist of the group of seven astronomers who investigated the motions of nearby galaxy clusters in the 1980s and who proposed the “Great Attractor” to explain them. He worked extensively on the relation of the nature of the universe to inertia (Mach's Principle) and also on negative heat capacities. With his wife Ruth, a chemist, he investigated thermodynamic equilibrium in clusters of stars and galaxies. His last research dealt with problems in magnetohydrodynamics, telescope optics, cosmology, and relativistic physics.
