Nikola Tesla was born on July 10, 1856, in the village of Smiljan (part of the Austrian Empire at the time, which is located in modern-day Croatia). Because he was born during a severe lightning storm on the night between July 9 and July 10, his family often celebrated his birth on the 10th, which became his officially recorded birth date.

Nikola Tesla (10 July 1856 – 7 January 1943) was a Serbian-American engineer, futurist, and inventor. He is known for his contributions to the design of the modern alternating current (AC▸ (Air Conditioning, or Alternating Current (electricity), depending on context)) electricity supply system.

For further details, see Wikipedia.

William Huskisson MP▸ (Member of Parliament, or Mile Post (a method of measuring the railway in miles and chains from a starting point - usually London), depending on context) was the first person to be killed by a train while crossing the tracks, in 1830.  Many more have died in the same way since then.  Don't take a chance: Stop, Look, Listen.

"Level crossings are safe, unless they are used in an unsafe manner."  Discuss.

With the SI unit for magnetic flux density (or magnetic field strength)named after him, the Tesla (symbol: \(T\). It is defined as one Weber per square metre, the Weber (Wb) is the standard SI unit of magnetic flux.

The 'war of the currents' of the 1880's is a fascinating story
