Helvetica Neue is a Linotype subsidiary that was designed in 1983 at D. Stempel AG by the cumulative effort of Wolfgang Schimpf, Reinhard Haus, René Kerfante and Erik Spiekermann. It is an open type font with some Latin extension backed by Greek and Cyrillic design supports.
The font is a numerical design scheme characterized by structurally integrated set of widths and heights. Further to that, heavier punctuation marks, increased number spacing and enhanced legibility add some sort of exclusivity and style to the so called simple Helvetica Font.
