We'll tackle a different decade each week, starting with the turn of the century – the last century. Our first installment takes you back to 1900-1910, when a German-born physicist named Albert Einstein started changing our perspective of space and time, attorney general Charles Bonaparte established what would become the FBI and the invention of the forward pass saved football from extinction.
We don't expect you to agree with all of our picks, or even some of them. That's fine. Tell us what you think we've missed and we'll publish your list later.
