Ber Groosjohan started playing as outside left for Sparta Rotterdam at age 16, winning the Dutch Championship in 1915. Soon after he went to another major club in Rotterdam, VOC. Groosjohan earned 14 caps from 1920-24, scoring five goals. In the 1920 Olympic tournament he played all four matches as a central attacker. He was also selected for the 1924 Dutch Olympic team, this time on the right wing. Groosjohan returned home early from this tournament after his wife had given birth to a son, retiring from football shortly afterwards. After his active career he was manager of a company for fashionable women’s clothing in Rotterdam, which he later took over. At the age of 40 Groosjohan started playing again for the VOC and played into his 50s.
