Machines That Built the World

How, with a growing need for speed and efficiency, a few visionary companies, such as Black and Decker, Milwaukee and DeWalt, created the power tools that revolutionised how America was built

In 1893, sending information across America was a time-consuming process, prompting two rival inventors to try to improve things by introducing wireless communication.
