Twelve years after taking over an IOC recovering from its worst ethics scandal, Jacques Rogge is leaving with the Olympic body in much sturdier shape but facing serious challenges.

The 71-year-old Belgian steps down as president next Tuesday after steering the International Olympic Committee through a period of relative stability that spanned three Summer Olympics and three Winter Games.

Rogge is an orthopedic surgeon who competed in three Olympics in sailing. He is completing his term with a reputation for bringing a calm, steady hand to the often turbulent world of Olympic politics.

He took a hard line against doping and ethics violations and made peace with the U.S. Olympic Committee after years of bitter squabbling over revenues.

IOC members will elect Rogge's successor by secret ballot in Argentina on Sept. 10, with six candidates running.
