No biographical details are currently known.
I already had him saved as a possible generico in a few background roles from the 40's and 50's, when I spotted him in Los que no fuimos a la guerra, in which he plays an identical non-speaking role to Santiago Rivero. Since Rivero was credited I investigated further which led to his identification. It seems he was credited in 11 films, all in the early-mid 1960's and mostly in very small roles (5 of which I was unable to find), so with 6 confirmed credited roles we can be sure of the ID.
Since starting the topic a number of additional undocumented and uncredited roles have been found, making it apparent that he was working as a generico from at least the early 1940's.
