Samuel Alfred Mitchell - Eclipse Work

Eclipse Work

In 1900, he took what would be for him the first of ten eclipse expeditions. The May 28, 1900 eclipse took him to Griffin, Georgia with the United States Naval Observatory. Mitchell became a world-renowned authority on solar eclipses through his numerous expeditions, including trips to: Sawah Loento, Sumatra in the Dutch West Indies (May 18, 1901), Daroca, Spain (August 30, 1905), Baker, Oregon (June 8, 1918), San Diego, California (September 10, 1923), Van Vleck Observatory, Middleton, Connecticut (January 24, 1925), Fagernas, Norway (June 29, 1927), Niuafoou or "Tin-Can" Island, Tonga, in the South Pacific Ocean (October 22, 1930), Magog, Quebec, Canada (August 31, 1932), and Kanton Island, Kiribati (June 8, 1937), this time as the scientific leader of a National Geographic Society Expedition. An article entitled "Nature's Most Dramatic Spectacle" by Mitchell appeared in the September 1938 edition of National Geographic Magazine. These ten expeditions allowed him to write Eclipses of the Sun, summarizing his work on solar flash spectra, first published in 1923 and produced through five editions (5th edition, 1951). On the 1918 Oregon and the 1925 Connecticut eclipses, Mitchell was accompanied by the artist Howard Russell Butler (1856-1934), whose paintings of totality graced the old Hayden Planetarium of the American Museum of Natural History for many years.

Famous quotes containing the words eclipse and/or work:

    He who does something at the head of one Regiment, will eclipse him who does nothing at the head of a hundred.
    Abraham Lincoln (1809–1865)

    As for my own business, even that kind of surveying which I could do with most satisfaction my employers do not want. They would prefer that I should do my work coarsely and not too well, ay, not well enough. When I observe that there are different ways of surveying, my employer commonly asks which will give him the most land, not which is most correct.
    Henry David Thoreau (1817–1862)
