Leland was a great monetary economist, a wonderful economist outright, an important early member of the Virginia School, one of the best read people I’ve met, and he could speak and read eight languages, including Swedish. He was also a wonderful expositor, and a fine gentleman altogether. He was either an early or a late proponent of market monetarism, depending on how you wish to mark the calendar. Most memorably to me, he would entertain my pesky questions about economics, without tiring, even when I was at a young age. I am sorry to see him go. Here is Leland on Wikipedia and other entries.
