Designed by Friedrich Berthold in a single heavy and wide style, and first cast as metal type by H. Berthold AG in 1962. Not to be confused with Primus-Antiqua (Typoart, 1950). Berthold Fototypes offered both Primus and Primus-Antiqua as film type.
Priamos (Brendel, 1974–1978) expands the design into 7 weights. Its heaviest weight is not as heavy and wide as the original Primus, though.
