The modern research laboratory can be a large and complicated social organism.

The approach required more persistence than imagination, but it produced remarkable results.

I entered Harvard Medical School knowing nothing of research.

In my first publishable research, I obtained evidence that the replication of polio viral RNA engendered a multi-stranded intermediate, although my description of that intermediate proved flawed in its details.

Time... is an essential requirement for effective research. An investigator may be given a palace to live in, a perfect laboratory to work in, he may be surrounded by all the conveniences money can provide; but if his time is taken from him he will remain sterile.

My life in science has been rich and rewarding. I have sacrificed very little.
