William Hussey an astronomer who attended the University of Michigan, graduating in 1889. Hussey most notably discovered close binary stars. He returned to the University of Michigan as director of the Detroit Observatory from 1905-1926. This article, written by Hussey, is in regards to his most famous discovery and explains that his further observations have led to the discovery of 500 additional close double stars. As the director of the Detroit Observatory, he had a significant amount of influence on the actions of the astronomy department here. Other correspondences of his in the boxes revealed how hard Hussey pushed to make sure that Michigan’s astronomical observational tools were on the cutting edge of the times. This article was fairly simple to identify as pertaining to the department of astronomy. Looking through the files in Hussey’s boxes, however, it was clear that not everything in there related to astronomy. I looked for things relating particularly to his discovery of close binary star systems, and this was one of the most interesting things that I found.
