- Edward Emerson Barnard
Edward Emerson Barnard (
December 16, 1857– February 6, 1923) was an American astronomer. He was commonly known as E. E. Barnard, and was recognized as a gifted observational astronomer. He is best known for his discovery of Barnard's starin 1916, which is named in his honor.
He was born in Nashville,
Tennessee, to Reuben Barnard and Elizabeth Jane Barnard ("née" Haywood), and had one brother. His father died before his birth, so he grew up in an impoverished family and did not receive much in the way of formal education. His first interest was in the field of photography, and he became a photographer's assistant at the age of nine.
He later developed an interest in astronomy. In 1876 he purchased a convert|5|in|mm|sing=on
refractor telescope, and in 1881 he discovered his first comet. (But he failed to announce his discovery). He found his second comet later the same year and a third in 1882.
While he was still working at a photography studio he was married to the English-born woman Rhoda Calvert in 1881. In the 1880s a
Hulbert Harrington Warneroffered US$200 per discovery of a new comet. Edward discovered a total of eight, and used the money to build a house for himself and his bride.
With his name being brought to the attention of amateur astronomers in Nashville, they collectively raised enough money to give Edward a fellowship to
Vanderbilt University. Barnard never graduated from the school, but he did receive the only honorary degree Vanderbilt has ever awarded.

Holden, over access to observing time on the larger instruments and other issues of research and management.

In 1892 he made observations of a
novaand was the first to notice the gaseous emissions, thus deducing that it was a stellar explosion. The same year he also discovered Amalthea, the fifth moon of Jupiter. He was the first to discover a new moon of Jupiter since Galileo Galileiin 1609. This was the last satellite discovered by visual observation (rather than by examining photographic plates or other recorded images).
In 1895 he joined the
University of Chicagoas professorof astronomy. There he was able to use the convert|40|in|mm|sing=on telescope at Yerkes Observatory. Much of his work during this period was taking photographs of the Milky Way. Together with Max Wolf, he discovered that certain dark regions of the galaxywere actually clouds of gas and dust that obscured the more distant stars in the background. From 1905, his niece Mary R. Calvertworked as his assistant and computer.
Barnard's Staris named for Edward Barnard after he discovered in 1916 that it had a very large proper motion, relative to other stars. This is the second nearest star system to the Sun, second only to the Alpha Centaurisystem.
He was also a pioneering astrophotographer. He cataloged a series of
dark nebulagiving them numerical designation akin to the Messier catalog. They begin with Barnard 1and end with Barnard 366. 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".
He died on February 6, 1923 in
Williams Bay, Wisconsin, and was buried in Nashville. After his death, his exceptional collection of photographs was published in 1927 as "A Photographic Atlas of Selected Regions of the Milky Way", having been finished by Edwin B. Frost, then director of Yerkes Observatory, and Mary R. Calvert.
Between 1881 and 1892, he discovered fourteen different comets, three of which were periodic:
D/1884 O1(Barnard 1)
177P/Barnard(P/1889 M1, P/2006 M3, Barnard 2)
D/1892 T1(Barnard 3) - First comet to be discovered by photography
