Burton–Judson Courts (B-J/The Beej) is a dormitory complex at the University of Chicago. One of the few undergraduate residences located south of the Midway Plaisance, it is a castlelike edifice built in a gothic style similar to that of the University's main quadrangles.[1] Designed by the Philadelphia firm of Zantzinger, Borie & Medary, it was completed in 1931 at a cost of $1,756,287.[1] It is built around two courtyards named after the university's second and third presidents.[2] B-J was the first on-campus residence of eminent astronomer Carl Sagan, who lived in room 141 (See "Carl Sagan, A Life"). Burton-Judson contains six houses: Dodd-Mead, Salisbury, Linn-Mathews, Coulter, Chamberlin, and Vincent.
