[4] Although born on 29 March 1884 in Bilbao, his sporting career began in 1910, as technical secretary of the Real Sociedad, since he had his automobile representation business in the city of San Sebastián.

[6] An agreement was eventually reached in September, with the basis for unification being signed by the presidents of the two entities in dispute, Olave and Ricardo Ruiz Ferry.

[4] In 1924, in one of those turbulent assemblies, he was elected the 5th president of the Spanish Football Federation, a position that he held for two years until his resignation in 1926, being replaced by Antonio Bernabéu.

[4] In his functions as president, Olave had the task of heading the Selection Committee of the Spanish national team, a triumvirate made up of himself, treasurer José Rosich, and secretary Luis Colina, so he provisionally served as national coach in a match against Austria held at the Camp de Les Corts on 21 December 1924, which ended in a 2–1 victory thanks to goals from Antonio Juantegui and Josep Samitier.

[2][3][8][9] In March 1927, he was invinted to become the president of the federation again, but he instead offered to serve Spanish football in a lower step than the one he had occupied a few months before, thus being reconstituted as treasurer.
