We know that once we stop learning and call ourselves learned, we become useless members of the scientific society.

The war broke out, and for a number of years I lived in darkness, with the memory of the lakes, the trees and the skies of Sweden, until I returned in 1946 to spend two unforgettable years in the laboratory of Hugo Theorell.

Although attracted by the humanities, I had chosen medicine as a career, seduced by the image of the 'man in white' dispensing care and solace to the suffering. But science was lurking around the corner, in the form of an unpaid student assistantship in the laboratory of physiology.

Our investigations were very fruitful. They led to the discovery of a new cell part, the lysosome, which received its name in 1955, and later of yet another organelle, the peroxisome.

I started working at age thirteen. I'm a product of public schools, I'm a product of a public university. I started my first company when I was 21. I've subsequently never worked for anybody else. I started that first business when I was still in college.

I'm very grateful to have been able to work with so many talented filmmakers and actors during my career. I've learned so much from them. It's been my college, in a way.

The thing I really look for in this business is there are guys who are into football and there are guys who are in the profession for other reasons.

It's the people who are more insecure who feel the need to control and micromanage. But that's true of any profession and hierarchy with a boss. You have people who know you are competent enough to do your job, and then you have the ones that just hover around.
