Designed by Adrian Frutiger in 1988, Avenir has grown in popularity, with even Frutiger calling it his “masterpiece.” Avenir shows a more humanist approach to early Geometric sans serifs (like Futura).
Some people really hate Avenir, but I can’t see why. I’ve seen it used on big signs for major art institutions and in body text of books. It looks good in both places. Since it’s not as harsh as other Geometric sans serifs, it work all over.
