Campbell was a pioneer of astronomical spectroscopy and cataloged the radial velocities of stars. He was also recognized for his work in solar eclipse photography. In 1893 he discovered the Wolf Rayet star HD 184738 (also known as Campbell's hydrogen envelope star). He was made a director of Lick Observatory from 1901 to 1930. --Wikipedia __+__ Campbell received many prestigious awards for his long service, including: the Lalande Medal of the French Academy of Sciences (1903); Henry Draper Medal from the National Academy of Sciences (1906); Gold Medal of the Royal Astronomical Society (1906); Janssen Medal; Bruce Medal (1915); Foreign Member of the Royal Society of London (1918); Honorary Fellow of the Royal Society of Edinburgh (1920). __+__ I'm including the opening paragraph of Campbell's obituary written by R. Aitken it is very laudatory, praising Campbell's courage, and defending his suicide. All of his life William Wallace Campbell did difficult things . with high courage. There can be no doubt that the most difficult thing he ever did, and the one which required the highest courage, was to end his own life. Most who take their own lives do it from lack of courage. One cannot read the pitiful notes left by Dr. Campbell and bring that charge against him. We can do Dr. Campbell this justice and yield no whit in our disapproval of self-destruction.
