José María Barquín

José María Barquín Eguía was a Spanish footballer who played as a Forward for Athletic Club. He was one of the most important figures in the amateur beginnings of Athletic Club, being part of the commission that drafted the statutes to legalize the club and then becoming the club's first-ever treasurer on 11 June 1901. He was also a tireless sportsman who dedicated himself to all kinds of sports. The dates of his birth and death are unknown.

Athletic Bilbao
As the son of a well-off family in Bilbao, Barquín was sent to Britain to complete his studies, doing so in the Catholic St Joseph's College, Dumfries, where he met and befriended Enrique Goiri, a fellow Basque and a future teammate at Athletic Club. At the turn of the century, Barquín began playing football with Athletic Club, then an unofficial football club. In February 1901, a commission made up of Barquín, Goiri, and Juan Astorquia, was appointed to draft statutes and prepare regulations to legalize the company and thus turn their group of football pioneers into an official football club. Four months later, on 11 June, the statutes were read and approved, and a board of directors was appointed, to which Barquín was elected as an accounting treasurer and Goiri as secretary under the presidency of Luis Márquez. The club was then officially founded on 5 September 1901, in the infamous meeting held in the Café García, but due to unknown reasons, Barquín did not attend since he is not one of the 33 men who signed the documents that gave birth to Athletic Club.

Goiri then became one of the first footballers of the newly formed Athletic Club, playing as a forward. He featured in a few friendly matches against city rivals Bilbao FC in the Hippodrome of Lamiako, both as a player, but also as a referee, officiating at least two matches between the two sides, including a 2–0 win to Bilbao FC on 15 December 1901 and a 4–2 win to Athletic on 19 January 1902, the latter being the first time that a paid match was held in Vizcaya. He thus played a pivotal role in this historic rivalry that served as one of the drivers of football as a mass phenomenon in Bilbao since their duels aroused great expectation.
