Welcome to the Scientific American podcast, Science Talk, posted on September 9th, 2011.

I'm Steve Merski. This week on the podcast, everything that takes place in this flower,

in my brain, and in your heart and so on, depends on enzymes, on the right kind of catholics.

That's the legendary Christiane D'Div, who will turn 94 in October. He won the Nobel Prize for Physiology or Medicine in 1974 for the discovery of lysosomes and paroxysomes, organelles

within the cell. He's perhaps best known for his ideas about the origin of life on earth,

about which he's published widely and for the lay reader.

We spoke on June 30th at the Lindau Nobel laureates meeting in Lindau, Germany,

in a restaurant adjacent to the conference hall,

which, as you will hear, goes from empty to quite

busy while De Duve and I talk.

I'm very interested in how, in your own, the development of your own thinking, how your

early work on recognizing and characterizing the cellular organelles of the lysosome

and the paroxysome led to your later interest in origin of life issues.

Well, it's a long story.

My life is a long story.

What really started it was that will interest you.
