While at Cal Tech I talked a lot with Jon Mathews, then a junior faculty member; he taught me how to use the Institute's computer; we also went on hikes together.

In 1975 I met Alison Brown and in 1982 we were married. She works for Cornell Computer Services.

One other hobby of mine has been playing the oboe but I have not kept this up after 1969.

My graduate studies were carried out at the California Institute of Technology.
