played at Blegdamsfælleden in Copenhagen, and AB won 2–0 against the opponent BK Frem. In 1889, AB participated in the establishment of the Danish Football Association together with 21 football clubs from Copenhagen and five from the province. On April 27, 1889, AB won the Danish Football Association's first tournament, defeating the until then invincible club Københavns Boldklub. In the period 1890–1900, AB had great success and won the Copenhagen Football Championship eight times. In 1890 AB played the first Danish-Swedish football match in the history when Halmstads BK was defeated 3–0 away from home. Football was not yet played at schools at the time, and AB therefore started a junior department with the intention of recruiting talented young players. However, the department had to close again in 1897 due to the bad behavior of its members. In 1899, the club tried again and this time it had more success as the department's member count rose to 70 during the first year. The first two members of the new junior department were brothers Niels Bohr and Harald Bohr, who both later came to play on AB's first-team squad.

He always played with a white handkerchief in the pocket, which he used to measure the wind direction and strength before and during matches. Harald, who later became a world renowned mathematician, played four international matches with the Danish national team during his career. Niels Bohr became more famous outside the football field as a Nobel Prize winner and in his work as a professor, which was illustrated in a match against German football team Mittweida Tecnicum. In the match, Niels Bohr played as a goalkeeper, and as the ball rarely came near AB's goal, he spent the time leaning against one of the goal posts. Suddenly, a long ball was kicked toward AB's goal, which the crowd expected Niels Bohr to collect. However, he did not respond before a spectator shouted at him and the ball had already gone into the goal. After the game, he admitted that his thoughts were on a mathematical problem that he had attempted to solve by making calculations on the inside of the post.
