Diotima was designed by Gudrun Zapf von Hesse in 1948. It is named for Diotima of Mantinea, a philosopher and priestess in Plato’s Symposium. Zapf von Hesse is a German type designer, calligrapher and bookbinder. She ran a bookbinding studio in Frankfurt from 1946 to 1955. She also taught lettering, and was fascinated by letterforms. Diotima was released as metal type by the D Stempel AG foundry in the early 1950s and was later digitised by Linotype.
