Donald Iglehart was my thesis advisor. I did my graduate work in the Department of Operations Reserarch at Cornell University, and received my Ph.D. from Cornell, but I went with Don to Stanford University to write my thesis when Don accepted a faculty appointment at Stanford in 1967. Even though Don became a Full Professor then, many students mistook Don for a fellow student. Actually, in those days, being my advisor, Don was a lot older. He has gotten a lot younger over the years. Don was also very serious too, but he was serious about his porsche and his tennis game as well as research.
After completing my thesis in 1967-8, I spent the following year 1968-8 as a Visiting Professor in the Operations Research Department at Stanford. The load was pretty reasonable; I taught a few masters level courses. I like to say that I was the Masters Program that year. But I had time to do some research, including these three papers with Don. The first two papers are among our most frequently cited papers.
