Overview:We know about the swing. We know about the swagger. But what most Americans don't know about Venus Williams is how she changed the course of her sport. In a stunning case that captured the European public beginning in 2005, Williams challenged the long-held practice of paying women tennis players less than their male counterparts at Wimbledon.

And it was her poignant op-ed piece in The London Times that convinced many people that the Wimbledon tournament organizers were "on the wrong side of history." Roland Garros and Wimbledon finally relented in 2007. That year at Wimbledon, Venus became the first women's champion to earn as much as the men's singles winner (Roger Federer).
