Gunnar Setterwall

Carl Gunnar Emanuel Setterwall (18 August 1881 – 26 February 1928) was a Swedish tennis player who won four Olympic medals. In 1908 he won a bronze in the men's indoor doubles, alongside Wollmar Bostrom. Four years later he won three more medals. In the mixed doubles (with Sigrid Fick) and indoor doubles (with Carl Kempe) tournament he reached the final but lost both times. Sigrid Fick was also his partner in the mixed indoor event and together they won a bronze medal.

Setterwall's father, also named Carl, was a multimillionaire controlling much of iron works during the railway's development in Scandinavia. His son followed in his steps, eventually taking over the family firm.
