Henrik Enok Isidor Behrens (1868–1951) was the founder of the Swedish sports club Allmänna Idrottsklubben (AIK) and its first chairholder. AIK was founded on February 15, 1891, at the home of Behrens and his family in Stockholm, at the downtown address of Biblioteksgatan 8. Early life Isidor Behrens was born on January 3, 1868, in Stockholm. Behrens was of German descent after his father, Carl August Heinrich Behrens, who was born in Burgberg, Germany and came to Sweden in 1862. His mother Anna Charlotta Behrens (born Wretberg) was from Häradshammar in Östergötland. Isidor Behrens had two brothers and two sisters. Paul Behrens (1870–1949), Emanuel Behrens (1873–1949), Edit Thekla Ingeborg Behrens (1878–1881), Edit Charlotta Behrens (1882–1964). In other words, Isidor was the eldest of the siblings. Biography Behrens was the very first to compete for AIK, at the International Gymnastics and Sports Festival in Stockholm in May 1891 at Svea Livgarden's sports ground with 200 athletes as participants. Behrens and six other AIK members had signed up in various disciplines. Behrens was a short-distance runner. He competed in the 150 meters, but his time was not enough for the final place. Behrens then tried on many other sports within AIK, from kicking to speed skating, but he never won any really big successes as an active. It was as a leader and board member that he made a name for himself both within and outside AIK. After a short stay in Lidköping in 1895, Behrens moved back to Stockholm, where he lived the rest of his life. From his father he had inherited his profession as a typographer and later became a registrar. In 1896 Behrens married Anna Matilda. The couple never had any children together.

He promised to come to the anniversary party in the Grand Hotel's mirror hall. In the autumn of the same year he died, 83 years old. His grave is found at Norra begravningsplatsen in Solna.
