1. The computer
The first operational electro-mechanical computer was used to crack secret Nazi codes. Innovation has miniaturized computers while increasing their power exponentially: the transistor (1947), the integrated circuit (1959) and the microprocessor (1970), increased the speed to process data, while the hard disk (1956), modem (1980) and mouse (1983) boosted their power to make data accessible. They now fit in your pocket and the palm of your hand.

Think it was a Swedish mathematician that first broke the code language that the Nazi used.
