Abstract

On April 5, 1967, as this first volume of the Annual Review of Genetics was being prepared for publication, H. J. Muller died. The Editorial Com mittee had hoped to include a chapter written by him, but his other commit ments and failing health made this impossible. An appreciation of Dr. Muller and his work, written by G. Pontecorvo, is planned for Volume II.We remember Dr. Muller for his ingenuity in divising new experimental methods, his imaginative theoretical insights, and his ability and willingness to look far beyond the immediate implications of an experiment or idea. We also remember his strong convictions, his confidence in the social benefi ts of science and of genetics in particular, his intellectual and moral courage, and his undeviating adherence to principle. Those who knew Joe Muller per sonally remember his great intellect, his driving energy, his sympathy for mankind in the large, his sense of human dignity, and his zest for new knowledge.To H. J. Muller we dedicate this first volume of the Annual Review of Genetics. The influence of his ideas is abundantly apparent throughout the book.
