No biographical details are currently known, but from the films he appeared in he must have been based in Barcelona. He has one credit as "José Palomo Jiménez", so that could be his full name.
IMDb lists one role from 1941 which I have been unable to find, so it could be possible he was working as a generico throughout the 40's and 50's. His earliest roles found so far date from 1954, after which he worked steadily, both in small character roles and background generico appearances, through until 1978.
It would seem highly probable that there will be undocumented roles to be found. He was clearly already quite mature in the mid-50's, easily recognisible from his rather gaunt features and large ears and from the late 60's he kept a white beard.
