In the spring of 1936, I was introduced by friends to Jean Tatlock. In the autumn, I began to court her. We were at least twice close enough to marriage to think of ourselves as engaged.

My mother was born in Baltimore, and before her marriage, she was an artist and teacher of art.

I need physics more than friends.

I saw what the Depression was doing to my students. Often they could get no jobs, or jobs which were wholly inadequate. And through them, I began to understand how deeply political and economic events could affect men's lives. I began to feel the need to participate more fully in the life of the community.

I enjoy the spring more than the autumn now. One does, I think, as one gets older.

In the spring of 1929, I returned to the United States. I was homesick for this country. I had learned in my student days a great deal about the new physics. I wanted to pursue this myself, to explain it, and to foster its cultivation.
