3:00 PM 7/21/78 Dr Lederberg, I stopped by hoping to catch you but no luck . . . The scoop -- just finished my first year at Columbia P and S. ! Love it. I'm on a 3 week trip around California and Oregon but am returning this Monday. I may be able to get back to Stanford but doubt it . . . . Hopefully I'll get a chance to drop by at Rockefeller, hopefully with some advance notice. Best wishes and good luck. I look forward to seeing you. Mark Weidenbaum
