1Some facts about my timing: I was born in 1918 in a small town called Far Rockaway, right on the outskirts of New York, near the sea. I lived there until 1935, when I was seventeen. I went to MIT for four years, and then I went to Princeton, in about 1939. During the time I was at Princeton I started to work on the Manhattan Project, and I ultimately went to Los Alamos in April 1943, until something like October or November 1946, when I went to Cornell.

2I got married to Arlene in 1941, and she died of tuberculosis while I was at Los Alamos, in 1946.

3I was at Cornell until about 1951. I visited Brazil in the summer of 1949 and spent half a year there in 1951, and then went to Caltech, where I've been ever since.

4I went to Japan at the end of 1951 for a couple of weeks, and then again, a year or two later, just after I married my second wife, Mary Lou.

5I am now married to Gweneth, who is English, and we have two children, Carl and Michelle.
