Three Fonts of Computer Drawn Letters Detailed descriptions are given for three fonts of letters. Letter shapes are entirely described by numbers. The basic vectors are in a general form so the fonts may be easily drawn on a variety of computers and cathode-ray tubes. The fonts include both upper and lower case Roman letters, mathematical signs, and upper and lower case Greek letters. Design of the fonts is described. However, the principal contribution of this paper concerns the fonts themselves. CACM October, 1967 Mathews, M. V. Lochbaum, C. Moss, J. A.
