James Craig Watson Medal
Awarded for contributions to the science of astronomy. Established by the bequest of James C. Watson. Scheduled for presentation in 2014.
Jeremiah P. Ostriker (2012)
For his seminal contributions to the theory of the interstellar and intergalactic medium, his cosmological simulations that help illuminate the formation and evolution of structure in the universe, his theoretical contribution to the existence of Dark Matter halos around galaxies, and his dedication to the scientific and academic communities through service as provost, builder of the Sloan Digital Sky Survey and as a mentor of generations of young astronomers.
Margaret J. Geller (2010)
For her role in critical discoveries concerning the large-scale structure of the Universe, for her insightful analyses of galaxies in groups and clusters, and for her being a model in mentoring young scientists.
Michael F. Skrutskie and Roc M. Cutri (2007)
For their monumental work in developing and completing the Two Micron All-Sky Survey, thus enabling a thrilling variety of explorations in astronomy and astrophysics.
Vera C. Rubin (2004)
For her seminal observations of dark matter in galaxies, large-scale relative motions of galaxies, and for generous mentoring of young astronomers, men and women.
David T. Wilkinson (2001)
For elegant precision measurements by Wilkinson, his students, and their students, of universal radiation that is close to blackbody yet wonderfully rich in evidence of cosmic evolution.
Carolyn S. Shoemaker and Eugene M. Shoemaker (1998)
For their painstaking research, which led to the discovery of more than 800 asteroids and 32 comets, including their co-discovery of Comet Shoemaker-Levy, the first comet observed colliding with a planet.
Yasuo Tanaka (1994)
For his leadership in X-ray astronomy since its beginning, and his crucial role in enabling the U.S./Japanese collaboration in the ASCA mission, a beautiful example of international cooperation in sciences.
Maarten Schmidt (1991)
First to grasp the extraordinary distances and luminosities of quasi-stellar sources and a pioneer in their use to probe the outer limits of our universe.
R. B. Leighton (1986)
For his work as creator and exploiter of new instruments and techniques that have opened whole new areas of astronomy to us all--solar oscillations, infrared surveys, spun telescopes, and large millimeter-wave reflectors.
W. Kent Ford, Jr. (1985)
For his work in the area of image enhancement and galactic dynamics, which has contributed greatly to the characterization of the unseen matter in galaxies.
Stanton J. Peale (1982)
For his contributions to the dynamics of solar-system bodies, especially for calculations leading to the prediction of volcanic action on Io, dramatically verified by Voyager photography.
Charles T. Kowal (1979)
For his noteworthy astronomical discoveries, particularly of Chiron, Leda, and numerous supernovae.
Gerald M. Clemence (1975)
For his long and distinguished career in Dynamical Astronomy and his independent determination of a completely new and more accurate Theory of the Motion of Mars.
André Deprit (1972)
In recognition of his resolution of the problem of lunar motion around the earth through his adaption of modern computing machinery to algebraic rather than arithmetic operations.
Jurgen K. Moser (1969)
Wallace J. Eckert (1966)
For his pioneering contributions to scientific computing and to the theory of the motion of the moon.
Paul Herget (1965)
For his scientific accomplishments in celestial mechanics and orbit computation, and particularly for his contributions to the knowledge of the orbits of asteroids.
Willem J. Luyten (1964)
For his outstanding contributions to the understanding of "white-dwarf" stars.
Otto Heckmann (1961)
Yusuke Hagihara (1960)
In recognition of his noteworthy contributions to astronomy.
George Van Biesbroeck (1957)
For his noteworthy contributions to astronomy.
Chester B. Watts (1955)
Herbert R. Morgan (1951)
For his distinguished contributions to fundamental astronomy, more specifically his interpretation of transit circle observations.
Samuel A. Mitchell (1948)
For his observations of solar eclipses, in particular a detailed study of the spectrum of the chromosphere which has contributed notably to our knowledge of the sun's atmosphere.
Ernest W. Brown (1936)
Willem De Sitter (1929)
In recognition of his research in astronomy.
C. V. L. Charlier (1924)
For his outstanding contributions to astronomical science concerning motion and distribution of the stars, and in celestial mechanics.
Armin O. Leuschner (1916)
For the skill and ability shown in supervising the preparation of the tables of the Watson asteroids, involving original methods, and leading to results of value to celestial mechanics.
J. C. Kapteyn (1913)
In recognition of his bold and penetrating researches in the problem of the structure of the stellar universe.
David Gill (1899)
For his work in perfecting the application of heliometer to astronomical measurements, which has resulted in an important advance in astronomy of precision, especially in the determination of parallaxes of the sun and stars and of the position of the planets.
Seth C. Chandler (1894)
For his researches on the variations of latitude.
G. F. J. A. Auwers (1891)
For his researches in sidereal astronomy, including the reduction of Bradley's observations.
Ed Schoenfeld (1889)
For his services in cataloguing and mapping the stars visible in our latitudes, and especially for his recently published southern Durchmusterung.
Benjamin A. Gould (1887)
For his valuable labors for nearly forty years in promoting the progress of astronomical science.
