The department organized a retirement party for me on June 17.
I got a card with wishes, and a "Short tribute to Gregor von Bochmann" was presented by Daniel Amyot. Here are some photos from the party. I also got a souvenir from the Dean at the faculty's end-of-the-year party (see photo).
Several peope could not come to the party. Here are video messges from some colleagues; others send me an e-mail (see here), and Lucia Moura prepared a acrostic with the characters of my name. (Wikipedia on acrostic: "An acrostic is a poem (or other form of writing) in which the first letter (or syllable, or word) of each line (or paragraph, or other recurring feature in the text) spells out a word or a message"). Here it is:
Nourish your enthusiasm.
