Re: Pieter Hofstra

What an awful piece of news.

During his PhD, Pieter visited Genova while I was there and he shared a
flat above mine in the old town. He was not only a good neighbor but he
also became a good friend indeed. If I remember correctly, he had a degree
in Philosophy. His conversation was kind, clever and entertaining. We did
not always agree on academic matters but I always tried to meet with him
during the ct's to talk and recall our days in Italy under Pino's
protection. Last time was at the Bow Bar in Edinburgh where we talked about
his work with Jon and about how much he enjoyed being a father.
