David MacKay, 1944–2023.
David was already retired from IU by the time I started grad school there, but he and his wonderful wife Carole hosted grad students at their house weekly for discussion & dessert. Quick-witted, opinionated, kind-hearted, and erudite, David had a profound influence on me.
Even though I wound up leaving academe, I still recognize David’s influence on my life & my faith. And when I walk through my woods, I think of the times he took me on trips around his own woods in his side-by-side, driving like a maniac, with a look of maniacal delight on his face.
