Kelly: Great. Okay, why don’t you start with how you got to—

Knobeloch: Okay. Well, everybody who came here had their own particular path and mine wasn’t as spectacular as some of them, but it was interesting to me, and I guess it started with good ol’ Pearl Harbor day.  

Arno Roensch's Interview

Theresa Strottman: We are speaking with Arno Roensch.  We thank you for coming this morning.  To start off the interview, I was wondering if you could briefly tell me when and where you were born and something about your early education and training.

Arno Roensch: I was born in Berlin, Germany—1918. We came to this country in 1922.  I remember the boat we came on, it was called the S.S. Orbeta; it was a British vessel.  It took 21 days to cross the Atlantic.

Jay Wechsler's Interview

Jay Wechsler: Well, my mother was visiting her folks in New York when she decided that it was time, and I was the first child, and I guess she was a little surprised. So I was born in New York even though we didn’t live there. And as soon as we were able we were back in New Jersey, where she and my father lived. My father was a chemist and even at a young age he was always taking me into the plant where he worked, showing me things. And I kind of had a mechanical bend or bent.

Ben Diven's Interview

Ben Diven: All right. I’m Ben Diven. That’s spelled D-I-V-E-N. I was born and raised in northern California, and I went to school in my hometown of Chico, and fortunately there was a state college there so I could start college in my hometown. I took the two and a half years of physics and mathematics that they taught there. And then, after a break of a couple years to save enough money to be able to go to Berkeley, I then transferred to University of California at Berkeley. 

T-Plant

In early 1944, DuPont, the operating contractor at Hanford, foresaw the need for four chemical separation facilities. These facilities, designated the T and U plants at location 200-West and the B and C plants at location 200-East (the C plant was never built), would be located approximately ten miles south of the reactors.
