Richard Alfred Rossiter

Rossiter was born in Oswego, New York, on December 19, 1886. He graduated from Wesleyan University in 1914, and married Jane van Dusen in 1915. He taught mathematics at Wesleyan Seminary for five years before enrolling in the astronomy program at the University of Michigan. He earned a master's degree in 1920, and a doctorate three years later. His doctoral dissertation, a study of the spectrum of Beta Lyrae, demonstrated that the shift that it exhibited could be accounted for by stellar rotation. Rossiter and his wife had two children, Laura and Alfred. ==Career==

In 1928 Rossiter became the first director of the Lamont–Hussey Observatory operated in South Africa by the University of Michigan. During this tenure at the observatory, he discovered more than 5,000 double stars. His Catalogue of Southern Double Stars, published in 1955, was dedicated to W.  J. Hussey, one of the professors for whom the observatory was named. ==Published works==
