Bruce Lee (née Lee Jun-fan) was born at the Chinese Hospital in San Francisco on November 27, 1940 to Lee Hoi-chuen (father) and Grace Ho (mother).
The elder Lee was a leading Cantonese opera and film actor on tour in America at the time of Bruce's birth. The family returned to Hong Kong (specifically, Kowloon) shortly after Lee was born, and within months Japan invaded Hong Kong.
Bruce Lee would return to San Francisco in 1959 at the age of eighteen.
