Correspondence regarding an informal visit to meet with Professor Wolfgang Beerman at the Max-Planck Institut für Biologie, Tübingen, Germany, 8-10 November, 1971.
Crick had just submitted, to Nature, "General model for the chromosomes of higher organisms." On 22 September, 1971, he wrote to Beermann: "I enclose a preprint of a very short paper I have submitted to Nature. I cannot help feeling, after hearing your colleague Henning talk at Erice, that your own thinking may perhaps have developed on similar lines. I hope you will excuse the very brief reference to your own work, but I found your 1966 article so clear that I thought it best to give it as a general reference ... It would be of great assistance to me if I could visit you some time in October for a day or so to discuss the model with you and to give me the opportunity of getting a proper grasp of all the recent work of you and your colleagues, so that I can do it full justice in my next paper."
