Bruce Jenner was known as the world's greatest athlete after her triumphant taking of the gold medal in the 1976 Olympic's men's decathlon. Now for better or worse, Caitlyn Jenner is perhaps the world's most famous openly transgender woman. Raising questions surrounding social constructs like gender and sexuality, Jenner came out in 2015 in an interview with ABC's Diane Sawyer. Later, she unveiled herself to the world as Caitlyn in a stunning Vanity Fair cover story. While she definitely did not spark the vibrant debate over gender and sexuality, Jenner added her voice to this national conversation.
