Publisher's Synopsis
Edward Singleton Holden (November 5, 1846 - March 16, 1914) was an American astronomer and the fifth president of the University of California. Early years;He was born in St. Louis, Missouri, in 1846 to Jeremiah and Sarah Holden. From 1862-66, he attended Washington University in St. Louis, where he obtained a B.S. degree. He later trained at West Point in the class of 1870.Career: In 1873 he became professor of mathematics at the US Naval Observatory, where he made a favorable impression on Simon Newcomb. On August 28, 1877, a few days after Asaph Hall discovered the moons of Mars Deimos and Phobos, he claimed to have found a third satellite of Mars. Further analysis showed large mistakes in his observations.[2] He was director of Washburn Observatory at the University of Wisconsin-Madison from 1881 to 1885. He was elected a member of the American National Academy of Sciences in 1885. He discovered a total of 22 NGC objects during his work at Washburn Observatory.He was president of the University of California from 1885 until 1888, and the first director of the Lick Observatory from 1888 until the end of 1897. He resigned as a result of internal dissent over his management among his subordinates. While at the Lick Observatory, he was the founder of the Astronomical Society of the Pacific and its first president (1889-1891).In 1901 he became the librarian of the United States Military Academy at West Point, where he remained until his death. ....Frederick William Herschel, KH, FRS (German: Friedrich Wilhelm Herschel; 15 November 1738 - 25 August 1822) was a German-born British astronomer, composer and brother of fellow astronomer Caroline Herschel, with whom he worked. Born in the Electorate of Hanover, Herschel followed his father into the Military Band of Hanover, before migrating to Great Britain in 1757 at the age of nineteen. His works were praised by Mozart, Haydn (who met Herschel in London) and Beethoven.[citation needed]Herschel constructed his first large telescope in 1774, after which he spent nine years carrying out sky surveys to investigate double stars. The resolving power of the Herschel telescopes revealed that the nebulae in the Messier catalogue were clusters of stars. Herschel published catalogues of nebulae in 1802 (2,500 objects) and in 1820 (5,000 objects). In the course of an observation on 13 March 1781, he realized that one celestial body he had observed was not a star, but a planet, Uranus. This was the first planet to be discovered since antiquity and Herschel became famous overnight. As a result of this discovery, George III appointed him Court Astronomer. He was elected as a Fellow of the Royal Society and grants were provided for the construction of new telescopes.Herschel pioneered the use of astronomical spectrophotometry, using prisms and temperature measuring equipment to measure the wavelength distribution of stellar spectra. In addition, Herschel discovered infrared radiation. Other work included an improved determination of the rotation period of Mars, [4] the discovery that the Martian polar caps vary seasonally, the discovery of Titania and Oberon (moons of Uranus) and Enceladus and Mimas (moons of Saturn). Herschel was made a Knight of the Royal Guelphic Order in 1816. He was the first President of the Royal Astronomical Society when it was founded in 1820. He died in August 1822, and his work was continued by his only son, John Hersche
