"Turning to the high jump, McAllister said photographs taken by a German anthropologist showed young men jumping heights of up to 2.52 meters in the early years of last century."

Does this mean that people were jumping 2.52 in the early 1900s?! If so, did they use the Fosbury Flop and it faded out after that? Because if not, they probably jumped that height with the Scissors-Jump, which seems highly unlikely...
