>Today I visited the website of Christof Lange, oh sorry, I mean Christof Wollenhaupt. Until today I thought it were two different persons, but it appears that he married two years ago and has changed his last name.

I'm not sure about US (I know a woman can keep her own last name, can add a second last name or can change her last name after being married), but in Russia you can change your last name to your wife's name. It rarely happens, though.
