Talk:Alberto Errera

This article definitively states that Errera was the creator of the Sonderkommando photographs However, the relevant link only suggests as much. Is there any proof he took these photos? — Preceding unsigned comment added by Dstone6 (talk • contribs) 02:58, 17 April 2016 (UTC)

Participation in the Uprising of 1944

I don't understand the meaning of this sentence:

According to Filip Müller,[10] Leon Cohen[9] and the historian and fellow prisoner Hermann Langbein,[11] 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.

Is it saying that Hermann Langbein participated in the preparations for the Sonderkommando Uprising or that Alberto Errera participated?----CarlosVdeHabsburgo (talk) 14:08, 17 April 2020 (UTC)
