BETWEEN 1881-1892 HE DISCOVERED 15 COMETS, THREE OF WHICH WERE PERIODIC (COMETS WITH ORBITAL PERIODS OF LESS THAN 200 YEARS), AND CO-DISCOVERED 2 OTHERS
EDWARD EMERSON BARNARD (1857-1923) SIGNED CARD, “Very Respectfully, E. E. Barnard”, on a card4 x 2.5, by the American astronomer who was known as a gifted observational astronomer and is best know for his discovery of the high proper motion of Bernard’s Star in 1916, which is named in his honor. He discovered proof of the “spokes” of Saturn. In 1892 he made observations of a nova and was the first to notice the gaseous emissions, thus deducing that it was a stellar explosion. In 1895 he joined the University of Chicago as a professor of astronomy. Much of his work during this period was taking photographs of the Milky Way: He was a pioneering astrophotographer, which is photography or imaging of astronomical object, celestial events, and areas of the night sky. His Bernard Catalogue lists a series of dark nebulae, known as Bernard objects, giving them numerical designations from Bernard 1 to Bernard 370. He published his initial list with the 1919 paper in the Astrophysical Journal, “On the Dark Markings of the Sky With a Catalogue of 182 such Objects”. After his death, many examples of his exceptional collection of astronomical photographs were published in 1927 as “A Photographic Atlas of Selected Regions of the Milky Way”. The card is in fine condition, with minor age toning and the date, “1905”, in another hand on lower left.
