Now, when I went to Columbia I had to pick a major. Now, I originally wanted to go to medical school and I had signed up for that, but they told me much later... I only, I was only at the summer session in Columbia and then I went back. By that time my, my first wife had moved to California and that’s how I, I went out to Berkeley. She was already registered there. And, on the GI Bill, you know, I took the pre-med program, but then when I got through my... the VA, or whoever was in charge of, I guess, it’s the VA that does that, they said to me, you don’t have enough GI credits to finish a medical education, under this programme, which was called PL16, because you had a medical discharge you have to be able to be employed at the end of your education, so you’ve got to pick a different career objective, okay. So, that’s how I decided to go into biochemistry. I, I picked a biochem major. And, so when I finished, however, 2 years at... Berkeley, my wife applied, I’d already been married by that time and she applied to medical school and got into Temple, and then we went, moved from Berkeley where we’d been living in Oakland, to New York. And, when I got to New York I signed up at Columbia but I couldn't get into medical school at that point and I wasn’t going to be able to get the money for it, either. So, I became a, a chem major at Columbia and I went to, to Columbia to continue, and I graduated in ’49 from there, and that was when I ran into the problem of finding a job.
