Adolfo Pérez Esquivel (born November 26, 1931) is an Argentine activist, community organizer, art painter, writer and sculptor. He was the recipient of the 1980 Nobel Peace Prize for his opposition to Argentina's last civil-military dictatorship (1976-1983), during which he was detained, tortured, and held without trial for 14 months; during that period he also received, among other distinctions, the Pope John XXIII Peace Memorial.

Wikipedia

The key word in the above reference from Wikipedia is activist. In Argentina, my place of birth, we prefer militante. The word has no connection with the more violent English equivalent militant. An Argentine militant does not tote guns. An Argentine militant is steadfast in his/her beliefs and acts but usually avoids violence.

Some years ago Pérez Esquivel came to town and I was able to snap 10 exposures. My favourite had him smiling at my camera. 

Yesterday was the last day for me to get all my photographs ready and give them to Nora Patrich who was on her way to Buenos Aires today. We are having a joint show at the Galería Vermeer on September 20. Somehow my portrait of Pérez Esquivel was to wishy-washy. He doesn’t look very militante in it. Then at the last possible moment, yesterday in the afternoon I spotted the 7^th exposure.

Now I feel that my photographs for our show will be balanced and its Argentine contents just fine.
