Steward Observatory - University of Arizona

Steward Observatory was officially established in 1916 through the foresight and perseverance of its first director, Andrew Ellicott Douglass, and a generous bequest made by Mrs. Lavinia Steward in memory of her late husband, Henry B. Steward. Astronomers here are among the national and international leaders in observational and theoretical research in astronomy. At the same time, they are making breakthroughs in related technology development -- from new light detectors to giant telescope mirrors -- that promise to be a catalyst for a renaissance in optical and infrared astronomy.
