Fencing Alesson was a man of great culture and very well regarded in the sporting environments of the late 19th and early 20th centuries in Barcelona, as he represented the prototype of the sportsman, a man who enjoyed all the sports and practiced most of the ones who were in fashion at that time, such as fencing and football. In 1893, he became a fencing teacher at the
Gimnàs Mèdic de Barcelona (Medical Gymnasium in Barcelona), and between 1897 and 1898, he opened the armory that bore his name, where some of the best fencers were trained, such as
Alfonso Ardura, a future president of the and of
RCD Espanyol, or
Alfredo Conde.
Catalan Football Federation and At the turn of the century, several clubs were informally playing football matches in Catalonia, so on 11 November 1900, Alesson, together with representatives of eight clubs, founded the
Asociación de Clubs de Football de Barcelona (AC de F.) in a room on
Carrer Archs in Barcelona. This was the body that regulated the first rules of Catalan football, and that six years later became the
Catalan Football Federation. He was elected as its first president, with his mandate lasting from the entity's foundation until November 1904, when he was replaced by
Josep de Togores. In the following week, on 18 November, on the occasion of the inauguration of the first
FC Barcelona field, next to the Casanovas hotel, the
AC de F. published its first football regulation. ==Other activities==
