Henk Barendregt 60

On 18 December 2007,
Henk Barendregt will turn 60.

We celebrate this occasion with
a one-day symposium in Nijmegen on 17 December with invited
speakers and a reception.

At the symposium, Henk received the first copy of a book dedicated to him: a collection of essays by the invited speakers and many of Henk's former PhD students.
