zanzibar: It's a little sad to report, but according to this site:http://nidodeerratas.blogspot.com/2...
<IM Oscar Quiñones> mentions Sumar, giving (1933-2007) as his lifespan.
I found another mention of the player on p145 of <Jaque perpetuo> by Marco Martos (2003):
<Oculto "Julio Súmar" en la mente, ganandole a Eliskases, al gran Larsen, solo en el Mar del Plata, con sus fichas, sacando de su cofre las jugadas que estaban escondidas varios siglos. Es luchador de gran ciencia, afanoso jugador del final, famoso, lento en las maniobras endiabladas, terco en la defensa de su rey, el invicto en mil batallas. Hoy lo veo, atento acomodando los trebejos, negro o blancos en la calle, y jugarán muchos desconocidos que no saben que Julio Súmar es maestro y calla.>
<Stealthy Julio Sumar in mind, beating Eliskases, the great Larsen, just in Mar del Plata, with their chips, pulling from his box moves that were hidden for centuries. It's great science fighter, eager player end, famous, slow maneuvers in the devilish, stubborn in defending their king, undefeated in a thousand battles. Today I see, attentive accommodating chessmen, black or white in the street and play many strangers who do not know that Julio Sumar is a teacher and silent.>
