Peter Lee Jung-sum
Elder brother of Bruce Lee and assistant director of Hong Kong Observatory.
Peter Lee Jung-sum (23 October 1939 – 3 September 2008) was a Hong Kong meteorologist who served as assistant director of the Hong Kong Observatory. He was also a world-class fencer and the older brother of Bruce Lee.
Born in Hong Kong, Lee was the first child of Lee Hoi-chuen and Grace Ho. He studied at La Salle College, where he did well in both academics and sports. He took up fencing and later got his brother Bruce, then aged about 11 to 14, to join him in lessons. In March 1958, Lee won the first Inter-School Fencing Competition. That July, he fenced for Hong Kong at the 1958 British Empire and Commonwealth Games alongside José Marçal, Pedro Marçal, Reuben Lynn, and Hung Hak-yau. Lee won his first-round match but did not advance to the quarter-finals; Hung reached the final in the individual foil event.
In May 1959, Lee visited Bruce in Seattle for a short time before moving on to Minnesota for his studies. He graduated from the University of Minnesota and returned to Hong Kong. In 1983, he earned a PhD from the University of Hong Kong’s Department of Electrical Engineering, with a thesis titled "A ground clutter processor for the Royal Observatory's 10-cm meteorological radar." During the 1960s, he taught briefly at La Salle College and then joined the Royal Observatory Hong Kong as assistant director, where he made important contributions to improving the observatory’s ability to detect tropical cyclones. Starting in 1968, he coached the La Salle fencing team, leading it to eleven Inter-School Fencing Championship wins over thirteen years.
Lee’s younger brothers were Bruce Lee and musician Robert Lee. Through Bruce’s marriage to Linda Lee Cadwell, he was uncle to actors Brandon Lee and Shannon Lee. Lee married Eunice Lam in 1966, and they had a son, Lee Hoi-ho. The couple divorced in 1971 due to personality differences. In 1980, he married Mary Cheung, winner of the 1975 Miss Hong Kong pageant; they had a son, Lee Wai-ho, and a daughter, Lee Yuk-yee. They divorced in 1995.
After retiring, Lee moved his family first to New Zealand and later to Melbourne, Australia. He died of a heart attack at home on 3 September 2008. His body was cremated, and his ashes were returned to Hong Kong.
