Nikola Tesla was an eccentric genius with the mind of a scientist, the imagination of a poet, and the voice of a prophet. One hundred years ago, he pointed the way toward robots, radio, radar, remote control, the wireless transmission of messages and pictures. His system of alternating current is the basis of the electrical grid that makes possible daily life in the 21st century. His imagination carried him beyond his own time. He was a visionary with an exhilarating sense of the future who was largely forgotten - and then rediscovered today.
