::I have reverted AnkhMorpork changes. 

 ::First I made some – very innocent and well documented – corrections of the dates of Klein’s birth and death as well as which IDF unit he belonged to at the time of death.  Brewcrewer reverted all my changes. I explained in some detail his error but he persisted. All my subsequent explanations fell on deaf ears. I didn’t think that this was a very important point, so I relented but added  on his totally undocumented and unsourced - and incorrect - claims. The present version of Wikipedia is thus the only “source” I’m aware of that replicate these obvious typos.  

 ::Then AnkhMorpork comes along and twice within 1,5 hour removes every single word I had added to the article, including important well-sourced material. Brewcrewer readily supported these obvious violations of WP:1RR. 

 ::Please note that I don’t mind if AnkhMorpork reintroduces his Telegraph source. I just didn’t see what it added that wasn’t already covered.
