Deletion of Till Tantau (3rd nomination)

Comment: For this area, the most accurate representation of his research publication record is the one in DBLP, http://dblp.uni-trier.de/pers/hd/t/Tantau:Till, although it doesn't have any measure of impact such as citation counts. I stand by my delete in the previous AfD: citation record not yet strong enough for #C1 and no evidence of -based notability for beamer. Re Xxanthippe's comment about this being a highly cited field: yes and no. The field is on the border between mathematics and computer science, and is much more highly cited than pure mathematics, but not quite as high as more systems-y computer science

Comment: Since we're going back to 2-year-old arguments, I guess I'll repeat what I said, as well. Without |waxing too much, we have numerous articles on significantly more obscure figures in the programming language community that have handily survived AfD, like Mark Jason Dominus or Audrey Tang. The previous AfD resulted in some good RSs that mentioned him and his work by name. It's easy to check the German media and find lots more commentary on his activities as a researcher and educator, for example the national daily Die Welt and the Lübecker Nachrichten both have http://www.welt.de/regionales/hamburg/article151741682/Uni-und-FH-Luebeck-verbessern-Studienbedingungen.html articles on Tantau's educational program at Lubeck. I've added these
