His father, Martí de Riquer, Marquis of Benavent, was a senior leader of the Carlists of Catalonia, while his mother, Elisea Ynglada, belonged to a family of intellectuals and artists (including writers such as Joseph and Wifred Coroleu and painter Ricard Modest Urgell).

"Between 1886 and 1898 he fathered nine children (three of whom died in infancy) and it was this responsibility with its attendant economic pressures which doubtless gave added, even urgent stimulus to Riquer's professional dedication.

"It was in Beziers that Riquer painted the first canvasses of his apprenticeship, and it was there that clear signs of a powerful artistic vocation, doubtless inherited from his mother, came to be prominent in his life.

The diversification of his work continued in the following years by designing jewelry, programs, furniture decoration and ceramic painting.

He made posters, etchings, illustrations in books and magazines, certificates, postcards, stamps, menus, sheet music, business cards and bookplates (which Lluís de Yebra documented 142 articles between 1900 and 1924).
