Biographical Note
Wallace John Eckert received his Ph.D. in astronomy from Yale in 1931
and became part of the faculty at Columbia that same year. He established the
Thomas J. Watson Astronomical Computing Laboratory in the early 1930s and
strongly urged IBM to develop a scientific calculator. His book,
Punched Card Methods in Scientific Computation
(1940), influenced the development of the electronic computer. In 1940, Eckert
left Columbia to become the director of the Nautical Almanac Office of the U.S.
Naval Observatory. After World War II, Eckert returned to Columbia. During this
period he also worked with IBM in the development of the Selective Sequence
Electronic Calculator (SSEC). He retired from Columbia in 1967 and became an
IBM Fellow.
Scope and Content Note
The collection contains correspondence, astronomy lecture notes,
drafts of publications, research notes, and miscellaneous materials relating to
Eckert's work in astronomy, celestial mechanics, and punched card systems. The
collection includes a letter to G. W. Baehne of IBM regarding the development
of a machine for scientific calculations (1934), correspondence relating to the
operation of the Thomas J. Watson Astronomical Computing Bureau, photographs of
Eckert, and drafts of publications. The drafts represented include
The Position of the Moon Computed Directly from
Brown's Theory, Punched Card Methods in Scientific
Computation (1940), and Faster, Faster
(1955), a book about the IBM-Naval Ordnance Research Calculator. Correspondents
include L. J. Comrie and Dirk Brouwer.
