The inspiration for this font I found on a gdr tenants index board, on wich movable white plastic capital letters were fixed by a thick line to the wooden board. This line is an important part of the font’s appearance. But there is also a variant without the line, which shows how the letters appeared when fixed behind a thin bar on the board.
In 2006, the Hochschule der Künste Bern (HKB) asked me to design the missing lowercase letters, to be used for the signagesystem, cut into metal. Also, the Tephe HKB now provides diacritics with the accents accrued directly to the glyphs. The Tephe HKB is an exclusive OpenType font for the Hochschule der Künste Bern.
