It summarizes exactly what I've felt since I first encountered his fonts, which is that they have an amazing "neutralness" to them. The Avenir font started with Futura and smoothed out its distinctive quirks. I sometimes have to look closely before being sure a font is really Avenir, just because it lacks any imperfections that might betray it as something similar, like Gotham.
His fonts might never be as famous as others because their distinctive characteristic is how impeccably unobstrustive they are.
"The Man of Black and White: Adrian Frutiger" (2005) was released in Swiss German and German in DVD format. It's also listed on amazon.de [2] but seems to be out of stock at the moment. The San Francisco Public Library [3] seems to have a copy though.
Sebastian Rohner of R.Films shot an interview with Adrian Frutiger at his home in Switzerland in 2007. It's available in German on YouTube [4].

"Just My Type", Simon Garfield's wildly popular book on typefaces, has a chapter titled "What is it about the Swiss?" which has a whole section dedicated to Frutiger. [2]
Frutiger's design philosophy is beautifully reflected in this quote: "If you remember the shape of your spoon at lunch, it has to be the wrong shape. The spoon and the letter are tools; one to take food from the bowl, the other to take information off the page... When it is a good design, the reader has to feel comfortable because the letter is both banal and beautiful."
Edit: Frutiger did a very detailed interview during the 1998 ATypI conference that was published in the graphic design journal, Eye, in 1999 [3]. Long read, but worth it to understand the man and his work.
Linotype has published an excellent obituary [4].
"Adrian Frutiger Typefaces: The Complete Works" is available on amazon.com [5] and amazon.co.uk [6]. A sneak peak is on ISSUU [7].
