Early life and family
Philippe Washer was born on 6 August 1924. He is the son of Jean Washer, another Belgian tennis player and textile industry mogul. Her mother, Simone van der Straeten, was the daughter of Ernest Solvay, founder of Solvay International Chemical Group. Philippe had three brothers: Paul Washer, president of the Chemical Industry Federation of Belgium and director of the Solvay company; Jacques Washer, antiquarian who died in the Swissair Flight 316 crash; and Edouard. They were also the cousins of famous sportscar racer Olivier Gendebien. Philippe started playing tennis at the age of six. He was coached by his father. He won his first tournament on 9 May 1940 in La Rasante just one day before the Battle of Belgium during which he volunteered to join the Belgian Army. In 1942 he won the French junior championships. 
Washer won the Belgian National Championships nine times consecutively between 1945–1954, except for 1950 when he was forced to retire from the competition due to illness. In 1952, he reached the semifinal of the Royal Belgian Tennis Federation Fiftieth Anniversary tournament. In 1957, he reached the Inter-Zonal Zone Finals of the Davis Cup with the Belgium Davis Cup team. The same year he won the Lebanon international tennis championships by defeating Warren Woodcock. In 1967 he came back from retirement to win the Belgian National Covered Courts Championship doubles, partnering with Jacky Brichant. Also after retirement, he won the Wimbledon Veterans' Doubles with Jaroslav Drobný four times from 1968 to 1971.
Washer retired from tennis in 1961, moved to Switzerland and subsequently started playing golf. In 1964 he represented Belgium in the Eisenhower Trophy. In 1955 he lent his own Ferrari 250 Europa GT Pinin Farina Coupe car to Olivier Gendebien who drove it in the Liège-Rome-Liège rally and finished third. After retiring he served as the president of the Royal Léopold Club between 1983 snd 1994, which his family saved from bankruptcy in 1948. He remained its major shareholder afterwards.
