President of the International Olympic Committee Games grew to become the most important sports event. De Coubertin created the modern pentathlon for the 1912 Summer Olympics. He subsequently stepped down from the IOC presidency after the 1924 Summer Olympics, which proved much more successful than the first attempt in Paris in 1900. He was succeeded as IOC President in 1925 by Belgian Henri de Baillet-Latour. De Coubertin remained Honorary President of the IOC until his death in 1937 in Geneva, Switzerland. Henri, Comte de Baillet-Latour was elected IOC President in 1925, after the founder of the modern Olympic Movement, Baron de Coubertin, stepped down from the
Secretary-General to the President June 1945, had a more fraught relationship with McDunphy and frequently baulked at following McDunphy's rules. McDunphy had a long-term impact on the presidency. His 1945 book "The President of Ireland: His Powers, Functions & Duties" was seen as the bible of the office by those seeking to restrict the post and its occupant. His restrictions, which were viewed as correct (or, if not correct, useful in enabling them to control and restrict presidents) by later civil servants, led President Erskine Childers to accuse one later Secretary to the President of having "the ghost of McDunphy behind you."
