No invention of anything occurs in a vacuum. I just had a quick look on google, loads of answers, but it looks like the game was invented by the pupils at Harrow school in the 1820s to 50s; the pupils invented a racquet for a game played in English prisons. Was it based upon the South American, handball with it's weird hand extensions?
It would probably be safe to say that the first squash game was played where it was invented, which looks like Harrow school. The game with Harrow type racquets reached the USA during the early 1880s.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
