TheHale Solar Laboratory is a historicastronomical observatory inPasadena,Los Angeles County, California, United States. Built in 1923, it was the laboratory ofastronomerGeorge Ellery Hale (1868-1938), a pioneering figure in the development of the discipline ofastrophysics in the United States. The building, a distinctive blend ofMission Revival andSpanish Colonial Revival styles, was designated aNational Historic Landmark in 1989.[2]
The Hale Solar Laboratory is located in a residential area on private property south of the campus of theCalifornia Institute of Technology, on the east side of Holladay Road between Lombardy and Orlando Roads. It is set well back from the street, down a narrow tree-lined lane. It is a roughly T-shaped concrete structure, with a tile roof. The stem of the T consists of the telescope tower and Hale's library/office and living area, while the top portion of the T historically housed electrical and ventilation equipment. The main entrance is at the base of the tower, set in an arch above which is an incised bas-relief tribute toAkhenaten, the Egyptian pharaoh who worshipped the sun godAten.[3]
The observatory was designed byReginald Davis Johnson (1882 - 1952),Gordon Kaufmann (1888–1949), andRoland Coate (1890-1958) and was completed in 1923.[4] The site's landscape master plan and gardens were designed byBeatrix Farrand.
After retiring as director at theMount Wilson Observatory, George Ellery Hale built the Hale Solar Laboratory as his office and workshop, pursuing his interest in thesun.[5][6] The observatory was where Hale refined thespectrohelioscope, making it possible to perform detailed observations of the surface of theSun. Hale's other wide-ranging contributions to the sciences include the founding of theInternational Astronomical Union, theAstrophysical Journal, and instrumental contributions to the founding of the California Institute of Technology.[3]
The Hale Solar Laboratory was declared aNational Historic Landmark in 1989.[2][3]
