Dhyan Chand
Dhyan Chand (1905 – 1979) was an Indian field hockey player who is considered to be one of the greatest players of all time. He was captain of the Indian Olympic team which won three Olympic gold medals (1928, 1932, and 1936). He scored more than 400 goals during his career.
Dhyan learned to play hockey when he joined the Indian army, at the age of 16. His real name was Dhyan Singh, and his brother Roop Singh also played in the Indian team.
Fun fact: Dhyan earned the nickname "Chand", which is the Hindu for "moon", because he used to practice hockey by moonlight, in the days before flood lights!
