Who served as the second President of the IOC from 1896 to 1925?

The correct answer is Baron Pierre de Coubertin, who played a pivotal role in the revival of the Olympic Games and served as the second President of the International Olympic Committee (IOC) from 1896 to 1925. His leadership was instrumental during a formative period for the IOC, as he was deeply committed to promoting the Olympics and the ideals of sportsmanship and international cooperation.

Under de Coubertin’s presidency, the modern Olympic movement gained significant momentum, with the establishment of the Olympic Charter and the expansion of the Games to include a wider range of sports and nations. De Coubertin's vision and philosophies around education and athleticism were foundational to the modern Olympic movement, helping to establish the principles that guide the Games today.

The other choices represent individuals who are notable in their own rights but do not fit the criteria of the second IOC President. Demetrius Vikelas was the first president of the IOC and played a key role in the first modern Olympic Games. Bill Bowerman is known for his influence in athletics and co-founding Nike but has no direct connection to the IOC's presidency. Thomas Bach is the current President of the IOC but has only served since 2013.
