- The most recent event under this heading is the Northwestern conference in the honor of Dale— with some very good and some not so good presentations…– featuring also some very (and some not so) entertaining speeches by former Mortensen students, co-authors, advisers etc, either at the dinner at the Northwestern Allen Center on Friday evening, or at the drinks & snacks session at Beverly and Dale’s splendid home (photo with Ija on their balcony) on Saturday evening.
