Hello,


I wonder if anyone has a copy of Deligne's letter to Looijenga from 1974 mentioned as reference [26] in Bessis' paper *Finite complex reflection arrangements are $K(\pi,1)$* from 2006, see <http://arxiv.org/abs/math/0610777>, and is willing to share it / make it publicly available.


We were recently proving some results generalizing particular aspects of things that are supposed to be proven in there, and we were asked about the historical background. Unfortunately, we cannot really provide an answer since we don't have access to the letter...

Eduard Looijenga provided a scanned version of the letter, which now can be found at

Many thanks for making it publicly available!


I also added a section on Deligne's hand-written letters to his [wikipedia page](http://en.wikipedia.org/wiki/Pierre_Deligne#Hand-written_letters), though I am not quite sure this is the right place to collect his publicly available letters.
