In the 1950s, 1960s and 1970s, Photon, under Billy Garth, built a large and rambling library of low quality typefaces, original in nothing but scripts. A group of higher quality material created at Deberny & Peignot for Lumitype Photon’s European arm under Higonet and Moyroud was added when the younger Higonet closed Deberny & Peignot. After Photon went out of business, the library was passed through Dymo (1975) to Itek (1979), and then to Unitex (1983), itself later acquired by Chorus Data Systems of New Hampshire.
