I married my wife Rhona in 1965.
We have two sons. I was a postdoctoral researcher at Argonne National Lab and MIT. I then joined the Audubon Society. From 1977 to 1981 I was Senior Staff Member for Energy at the President’s Council on Environmental Quality. From 1981-1986, I was a member of the Union of Concerned Scientists. I served as Senior Staff at the World Resources Institute from 1986-2004. My favorite memory is when I was at a Minneapolis Symphony concert in the top balcony at Northrop Auditorium. A young woman came in and saw that her seat had been taken, and I offered her the one next to me. That is how I met my wife. My favorite professor was Ian Richards. He was a math professor. He never carried notes. He would walk in and say, “Here is where we left off.”
