Letter from Thomas Gold to Dr Richard Feynman, Department of Physics, California Institute of Technology, Pasadena, California Asks if Feynman will be there when he comes to Pasadena again for a few days starting on 8 June, and if there is anything to be done at CalTech like speaking on pulsars or the moon. Enjoyed the evening with him. Has not yet written the play but expects to make a serious attempt in the summer. 13 May 1970
