Please suggest a paper that should be translated into English and posted on arXiv.

A few existing suggestions on MO are

• Die 5-fach transitiven Gruppen von Mathieu, Witt (DOI)
• Die Monodromie der Isolierten Singularitäten von Hyperflächen, Brieskorn
• Gèbres, Serre

I propose to have the translation done in an open source fashion, for example like this (switch to source mode on the upper left).
