Some Reminiscences About Shortest Spanning Trees

In 1951, I entered the graduate mathematics program at Princeton.

For a while, there was a joint Princeton- Bell Laboratories combinatorics seminar, which met alternately at the two locations. My first introduction to Bell Laboratories, where I subsequently have spent several decades, came in this connection.
