LOUIS 10, MISSOURI 12 December 1960 Dr. Joshua Lederberg Department of Genetics Stanford University Palo Alto, California Dear Joshua: Many thanks for your comments and suggestions. I appreciate particularly the suggestion regarding the Meynelis. We hope to exploit the opportunity to accommodate visiting professors as a possibly efficient means of learning about people and issues, getting some assistance in teaching, and avoiding, at the same time, making essentially irreversible commitments regarding per- sonnel before having lived in the microbiological arena for a year ,or two. I hope to get the chance to chat further with you next month in La Jolla or at Stanford. Sincerely, f i ve ltu iin Herman N. Eisen HNE : vb
