Here's one example of his generosity and kindness. When I arrived at OSU, one of the Vice Chairs assigned me a horrid interior office with a connecting hole to the men's room (see the November 5, 2018 story). After I put up with it for most of an academic year, near the beginning of spring quarter John presented me with a key. Our colleague Joe Neisendorfer was taking a new job at the University of Rochester, to start in the fall. Joe wasn't teaching in the spring quarter, and had moved out of his office early. John suspected that I would stay in my vent-for-the-men's-room office forever, if we left it up to the Vice Chair (who seemed to relish demonstrating his power over me---stories for another day). John took pity on me, and asked Joe to give him his office key, so that John could give it to me. Joe kindly agreed, and I moved into his office before the Vice Chair could assign it to anyone else. The Vice Chair hated me for it, since we had gone around him. But it was worth it to get a room with a view (and no men's room fumes).
If only there were more people like John Hsia.
