Roger Federer

Age: 30
Occupation: Professional tennis player
Previous TIME 100 Appearances: 1

Federer stands alone as the most accomplished tennis player of all time, having broken Pete Sampras' record of 14 career Grand Slam titles after defeating American Andy Roddick in a five-set thriller at Wimbledon. (Federer clinched championship No. 16 at the Australian Open in January.) The Swiss superstar has stayed classy throughout his remarkable run.
