The nine colophons (printer's marks) between the first and second story windows on the 1954 building (east side of Allen Hall) survey the history of printing. The choice of these images reflects the affection that so many alumni at the time still felt for the art of printing. Many, if not most, of them had taken typesetting and printing classes as part of their practical coursework in the School. The one with the inscription ‘ALDUS’ (second row, second from left) identifies the Aldine Press. Aldus Manutius (1449-1515) was a pioneering figure in publishing, printing, and typography. One of the School's most generous alumni, Paul Brainerd, co-founded the Aldus company in 1984 (named after Aldus Manutius) and developed the first layout program for the Macintosh computer, Pagemaker. He coined the phrase "desktop publishing."
