The Scottish-born American astronomer William Harkness (1837-1903) studied at LaFayette College and the University of Rochester before pursuing further studies in medicine in New York City. A surgeon in the Union armies during the Civil War, he also served as an aid in astronomy at the United States Naval Observatory and subsequently on the USS Monadnock. He discovered the coronal line K1474 while observing the August 1869 solar eclipse. As a member of the Transit of Venus Commission, he was in charge of the group at Hobart, Tasmania in 1879 and subsequently of that in Washington in 1882. Harkness contributed to the construction and improvement of telescopes and invented several astronomical instruments, including the spherometer caliper. He went on to serve as astronomical director of the Naval Observatory from 1894 through 1899 and director of the Nautical Almanac from 1897 through 99 and was president of the American Association for the Advancement of Science. His published works include "The Solar Parallax and its Related Constants" (1891). Fair .
