In drawing the Avenir® typeface, Adrian Frutiger looked to both the past and the future for inspiration. His goal was to reinterpret the geometric sans serif designs of the early part of the 20th century in a typeface that would portend aesthetics of the 21st century. He succeeded handsomely. In doing so, Frutiger added a bit of organic humanism to the design, freeing Avenir from the rigid geometric overtones of the earlier designs. Avenir is employed on signage at Dallas Fort Worth and Hong Kong international airports. The city of Amsterdam adopted Avenir as its corporate typeface in 2003. The original Avenir family is made up of designs with gradual weight changes in order to satisfy the needs of specific text applications. While the book and light weights have similar stroke widths, the book weight is well suited for body text, whereas the light was designed for captions and subhead text.
