*\ Universit 3/Rockefelle& THE ROCKEFELLER UNIVERSI Ye 1230 YORK AVENUE * NEW YORK, NEW YORK 10021-639 mi zZ Y Jay > a) 33>: a March 30, 1987 To: Dr. Joshua Lederberg From: Peter Model Re: Press Release I think the paper was by Schoenheimer & Rittenberg (or Rittenberg & Schoenheimer) but Rittenberg did all the isotope work, having just come from H. Urey's lab where he was a student. (Urey told him that there was very little future in isotopes as a physical chemist, but maybe some application could be found in biology?) I don't know how to bring in Benesch, since I never formally worked with him. JI hung around his lab a lot, and since he had little intellectual arrogance but was very self- centered, we tended to talk about his experiments rather than mine. Thats how I came to ask him why Oy uptake was always done in phos- phate rather than Tris, and that's how I came to ask him how much Pi was in the red cell anyway, which made him look it up, hence DPG. He always gave me credit for the suggestion (generous), but I would hate to arrogate any, especially now that he is dead, and Ruth is very sensitive. If you have any suggestion as to how, without being offensive, or grabby, please make it. Entity is fine - you're right, organism raises questions I don't want to raise. MAR 31 1387 ‘ CE cE THE PRESS
