No individual has done more to help me pursue a career in science than my wife of forty-five years. I met Enid Cassandra Morgan during the election campaign of 1948 when she was a Sunday school teacher, a leader of the youth organizations of St. Phillips Episcopal Church, and the head of Harlem Youth for the election of Henry Wallace.

My education in the public schools of New York City between 1932 and 1944 was an excellent preparation for a life in science. Because of the Depression, these schools were able to attract a remarkably talented and dedicated collection of teachers who encouraged their students to strive for the highest levels of accomplishment.

In 1890, nearly everyone died on the job, and if they lived long enough not to die on the job, the average age of retirement was 85.

Remember, what does 'retirement' mean? It doesn't mean that you're a couch potato. Leisure is not the same thing as rest. If you're bicycling five miles a day, that's leisure, but it certainly takes a lot of effort.

I had dropped out of school and was a runaway, so I didn't have family to fall back on if I didn't work. I didn't have a lot of other options of making money other than modeling.

In tennis, a lot of parents are accused of driving their kids into tennis. I would say I'm the opposite: I drove my parents into it. They didn't take it that seriously until I was about 11 or 12 years old, when they realised I had an opportunity to go pro.

Seeing the family is a very important part of my weekend.

I find being a mother is a huge advantage. Of course, I'm probably a little more tired than I might be if I didn't have children, but I think they provide me the balance that I need to keep my mind off of lifting.
