E. E. BARNARD
E. E. BARNARD
USA (1857 - 1923)
Best known for his discovery of Barnard's star in 1916, Edward Emerson Barnard was a gifted astronomer who grew up with little formal education. In 1876, he purchased his first telescope, a 5-inch refractor and discovered his first comet in 1881. In 1892, he discovered Amalthea, the fifth moon of Jupiter, making him the first to discover a new Jovian moon since Galileo in 1609. After joining Yerkes Observatory at the University of Chicago in 1895, Barnard spent great amounts of time photographing the Milky Way. Posthumously, his photographs were published in 1927 as A Photographic Atlas of Selected Regions of the Milky Way.
