Achievements

• His brother August Willem won the national championships in 1903 but died young, in the age of only 24, in 1908 in London. His sister Madzy won the ladies" doubles three consecutive times (1889–1901) and the mixed two consecutive time (1899–1900, partnering Karel Beukema) both streaks started from the inaugural championships. His breakthrough came when in 1904 he won a triple crown at the Haarlem International Championships (partnering Emilie Dolleman and J F Sol). On top of that he became the triple crown national champion of the Netherlands after he copied his brother, August"s singles feat from last year then claimed the doubles with Christiaan and finished the day with the mixed title partnering Louise Dolleman. In 1909 he won the mixed national championships after a three-year hiatus partnering Loes Everts.
