- I was born in Brooklyn in 1922. Both my mother and father were Russian Jewish emigrants who came to America in the early 1900's. My father was a tailor and my mother, a housewife. Though of limited education themselves, they instilled in me the values of intellectual achievement and the use of whatever talents I possessed.
- My Ph.D. thesis concerned the metabolic mechanism by which the end product of nitrogen metabolism in the earthworm is switched from ammonia to urea during starvation. I remember spending my nights collecting over 5,000 worms from the University campus green.
