While a lab Director can get done the things that he regards as important, he has the more important job of bringing out the best ideas of the broader scientific community.

Getting enough energy to satisfy the needs of the developing world without bringing on an eco-disaster is not going to be easy. It will require a marriage of science and technology with good international policy, something that is always hard to bring off. We need to get it right this time.

In 1948 I entered the Massachusetts Institute of Technology, undecided between studies of chemistry and physics, but my first year convinced me that physics was more interesting to me.

Since stepping down as laboratory director in 1999, I have devoted an increasing fraction of my time to international issues. I am involved with energy, environment, and sustainability issues, particularly as they involve new energy sources free of greenhouse gases.

Modern science is fast-moving, and no laboratory can exist for long with a program based on old facilities. Innovation and renewal are required to keep a laboratory on the frontiers of science.

Starving the future to feed the present is a mistake - it leads to obsolescence and stagnation. Sometimes it is hard to make this understood.

I was born on 22 March 1931 in New York, the elder child of Abraham and Fanny Richter.
