When we turn a light on, or plug in any device, we owe a debt to Nikola Tesla for his contributions to the design of modern alternating current electricity. In essence: the power grid. Tesla was born a Serb in the Austrian Empire on 10 July 1856. His father was a priest; his mother was known for inventing things to make their home life easier. She was also known for amazing mind — she could recite epic Serbian poems from memory.
