The Regular and Bold weights of Helvetica were redesigned for the Linotype machine; those alterations remained when Helvetica was adapted for phototypesetting. During the 1980s, the family was redrawn and released as Neue Helvetica. Schwartz's revival of the original Helvetica, his new Neue Haas Grotesk, comes complete with a number of Max Miedinger's alternates, including a flat-legged R.
Eight display weights, from Thin to Black, plus a further three weights drawn specifically for text make this much more than a revival - it's a versatile, well-drawn grot with all the right ingredients. The Thin weight (originally requested by Bloomberg Businessweek) is very fine, very thin indeed, and reveals the true skeleton of these iconic letterforms.
Available as a family of OpenType fonts with a very large Pro character set, Neue Haas Grotesk supports most Central European and many Eastern European languages.
