You've got to admire the patience of these researchers. "The identities and histories of prisoners in Nazi Germany's most notorious death camp Auschwitz have been uncovered following two years of painstaking research. Historians, archivists and IT specialists at the Auschwitz-Birkenau State Museum in Poland and the Arolsen Archives in Germany teamed up for the project. They searched though over 160,000 documents concerning the fate of around 30,000 men and women held in the camp where over 1 million people were exterminated or died from torture and exhaustion. One of those whose full details remained a mystery was Franciszek Jazwiecki, a Polish political prisoner who became known as the 'Portraitist of Auschwitz'. Deported to Auschwitz from Krakow, Jazwiecki was employed in the extermination camp's carpentry workshop and paint shop where he began sketching harrowing portraits of his fellow inmates. To keep his drawings secret from guards, Jazwiecki hid the portraits in his bed or clothes, but they were eventually discovered by SS officer Wilhelm Boger. One of the most feared camp executioners nicknamed 'Screaming Death' by the prisoners, Boger sentenced him to three months hard labour in a penal colony. Jazwiecki died in 1946, a year after being liberated." www.dailymail.co.uk/news/article-9347481/Researchers-uncover-previously-unknown-identities-prisoners-Auschwitz.html
