Named in memory of Victor Eugene Thoren (1935–1991), one of the foremost contemporary historians of astronomy and a faculty member in Indiana University’s department of history and philosophy of science for his entire academic career. Although Thoren’s research contributions were wide-ranging, they nonetheless focused on Tycho Brahe {see planet  (1677)} and his emphasis on accuracy in a manner never before thought possible. A copy of his monumental study, The Lord of Uraniborg: A Biography of Tycho Brahe, reached Thoren a few days before his tragic death, thus affording him an opportunity to enjoy, all too briefly, the fruits of his intellectual labors.
