Jacinto Francisco Fernández de Quincoces y López de Arbina (17 July 1905 – 10 May 1997) was a Spanish football player and manager, as well as President of the Valencian Pilota Federation. He was a central defender and is regarded as one of the greatest defenders of the inter-war era.
His brother Juan had a short career with Alavés, during which the siblings were teammates.[4] His nephew Juan Carlos Díaz Quincoces was also a professional footballer and a Spanish international, usually referred to as 'Quincoces' in recognition of his famous relative (conventionally the paternal surname Díaz would have been used). They worked together at Valencia as coach and player in two spells.[5]
Since Quincoces was a Basque pelotapala player before becoming a football professional, when his career finished, he was chosen by the Francoist authorities as President of the Valencian Pilota Federation, believing that Basque and Valencian handball sports were the same. Quincoces declared to the press several times that he was unwilling to undertake this task, but while he was in charge (late 1960s and early 70s) he promoted new measures that resulted in profit for Valencian pilota, such as the beginning of the Youth Championships, compulsory for the trinquets that wanted to host professional tournaments, this was the way pilotaris such as Genovés I and Xatet de Carlet began.
