TheHershey fonts are a collection of vector fonts developed c. 1967 by Dr. Allen Vincent Hershey at theNaval Weapons Laboratory,[1][2][3] originally designed to be rendered using vectors on early cathode ray tube displays. Decomposing curves to connected straight lines allowed Hershey to produce complex typographic designs. In their original form the font data consists simply of a series of coordinates, meant to be connected by straight lines on the screen. The fonts are publicly available and have few usage restrictions.[4]Vector fonts are easily scaled and rotated in two or three dimensions; consequently the Hershey fonts have been widely used in computer graphics,computer-aided design programs, and more recently also incomputer-aided manufacturing applications likelaser engraving.
Someglyphs were developed in four different versions, dubbed Simplex, Duplex, Complex and Triplex, which used different numbers of strokes to compose their contours.[4]
The fonts include Latin, Greek,Cyrillic, Japanese (kanji,hiragana andkatakana). Symbolic glyphs support mathematics, musical notation, map markers, as well as meteorological symbols. The fonts also exist inScalable Vector Graphics (SVG) format to support HTML 5.[5] Over 2,000 original plottings are defined. The font data for 1,377 (Occidental) characters was published byNIST in 1976.[6]
The Hershey fonts were a major influence on the design of Minotaur, a typeface produced by the Parisian type foundryProduction Type in 2014.[3] In 2015, Germangraphic designer Frank Grießhammer announced that he created an outline version that can be used in contemporary applications and it is released under anopen source license.[7]
