Alberto Israel Errera[1] (Greek: Αλβέρτος Ερρέρα, 15 January 1913 – August 1944) was a Greek-Jewish officer and a member of the anti-Nazi resistance.

[4] On the night of 24 March 1944, he was arrested by the Germans in Larissa, in addition to a group of 225 Jews,[5] and then jailed in the Haidari concentration camp.

[9] According to Filip Müller,[10] Leon Cohen,[9] and the historian and fellow prisoner Hermann Langbein,[11] Errera was among those who actively participated in the preparations for the Sonderkommando Uprising, alongside Yaacov Kaminski, Jankiel Handelsmann, Jukl Wrobel, Josef Warszawski, a man named Władek, Giuseppe Baruch and Zalman Gradowski,[12] among others.

On 9 August 1944,[21] during the transport from the crematoria of ash that was to be discharged into the Vistula, Errera tried to convince his three co-detainees (including Hugo Baruch Venezia and Henri Nechama Capon) to escape, but they refused.

The photographs were credited as anonymous or, by default, assigned to Dawid Szmulewski, who himself mentioned a Greek Jew named Alex.

The story of these photos was recorded in the writings of Alter Fajnzylberg, who evokes the figure of the Greek Jew named Alex (although he forgot the surname).

[24]However, in his diaries written immediately after the war, Fajnzylberg mentions the attempted escape of a Greek Jew named Aleko Errera.
