Note

As a child, British king George VI (1895–1952) was naturally left-handed. He was forced to write with his right hand, as was common practice at the time.

  • Apart from inconvenience, left-handed people have historically been considered unlucky or even malicious for their difference by the right-handed majority.
  • Throughout history, being left-handed was considered negative, or evil; even into the 20th century, left-handed children were beaten by schoolteachers for writing with their left hand.

Industrial Revolution

  • When Industrial Revolution spread across Western Europe and the United States in the 19th century, workers needed to operate complex machines that were designed with right-handers in mind.
