Optima is a humanist sans-serif typeface designed by Hermann Zapf and released by the D. Stempel AG foundry, Frankfurt, Germany and released in 1958.
Though classified as a sans-serif, Optima has a subtle swelling at the terminals suggesting a glyphic serif. Optima was inspired by classical Roman capitals and the stonecarving on Renaissance-period tombstones Zapf saw in Florence on a 1950 holiday to Italy.
Zapf intended Optima to be a typeface that could serve for both body text and titling. To prove its versatility, Zapf set his entire book About Alphabets in the regular weight. Zapf retained an interest in the design, collaborating on variants and expansions into his eighties.
