I don't believe it myself (the death of biography, not the teamwork). Publishers and readers like biographies, however historiographically teeth-grinding they turn out to be. Even better if the media can create a personal opposition to portray an issue - as with Venter and Sulston over ownership of the human genome. And both now have books devoted to them.
But Peter Dizikes' piece says a lot of other interesting things, too. He also lists some scientists ripe for biographical treatment including (according to Dan Kevles) Carl Sagan. That's odd: I've read two biographies of Sagan already.
Anyway, you can read Dizikes' piece here.
