A native Californian, Robert Aitken was educated at Williams College in Massachusetts. After teaching briefly in California, he worked at the Lick Observatory from 1895 to 1935. He was associate director seven years (while director W. Wallace Campbell was president of the University of California) and director from 1930 to 1935. Aitken made systematic surveys of binary stars, discovering thousands, measuring their positions visually, and calculating orbits for many. His massive New General Catalogue of Double Stars within 120 degrees of the North Pole allowed orbit determinations which increased astronomers' knowledge of stellar masses. He also measured positions of comets and planetary satellites and computed orbits. He was editor of the Publications of the Astronomical Society of the Pacific (PASP) from 1898 to 1942. He wrote an important book on binary stars, and he lectured and wrote widely for the public.
