Alexander Grothendieck's father
Alexander (Sascha) Schapiro, also known as Alexander Tanaroff, Russian Jew born in 1889, radical anarchist, imprisoned in Russia in 1907, condemned to death then pardoned because of his youth, lost an arm during an escape attempt, eventually released. He then left Russia, spent time in Belgium, Paris and Berlin, went to the Spanish Civil war in 35-36, returned disillusioned to Paris and was interned in the Camp du Vernet as an 'undesirable' in 1939, then deported to Auschwitz in 1942, where he lost his life. The first picture shows Sascha working as a street photographer in Berlin in the 1920's.
