Bernard Katz, Department of Biophysics, University of London to Brown Has just received his letter of 1 April - thinks only formality required is for Graddon to write to Feldberg and ask him if he is willing to write memoir - no need to involve Council - suggest Brown talk to Feldberg and say that he was not approached before because he had written Gaddum memoir and Council did not want to overburden him - has returned to work on his "various compost heaps" after illness and holiday in Dorset. 18 April 1969
