What is 'Tiger' Woods's first name

Tiger Woods's actual first name is Eldrick, given to him at birth. His father Earl Woods nicknamed him 'Tiger' in honor of his soldier friend Colonel Vuong Dang Phong, who was also known as Tiger. The nickname stuck and became his public identity, but Eldrick remains his legal first name. This is a classic example of a famous athlete being known by a nickname rather than his birth name.
