The Catalyst award page describes Frank perfectly:
Catalysts are elements or chemicals that can cause or accelerate reactions but do not, themselves, get used up. They are, in this case, people who make things happen by their presence and by what they do. They don’t necessarily do everything themselves, but they bring out and enable the best in the rest of us. They connect the rest of us, and facilitate our interactions so that we all can do great things. They connect us, and facilitate us so that we all can do great things.
Not only has Frank done a lot for accessibility, he’s behind a lot of the work on the open web, which we all enjoy and appreciate. Frank has helped many individuals live up to their true potential. Please see the 2009 Catalyst Award announcement page for more details on what Frank enabled, and how he did it. This award was an easy choice.
Anything is possible if you don’t care who takes the credit. Thanks again Frank, not only for teaching us that, but for all you’ve done for this community. We could use a few more people like you.
