Address of the President Sir Henry Dale, O.M., G.B.E., at the Anniversary Meeting, 30 November 1945

The annual number of Obituary Notices of Fellows of the Royal Society published today, and the names which have just been read to us, remind us of the losses from its Fellowship which the Society has suffered during the year now closing. I propose on this occasion to proceed next to the presentation of the Medals for 1945. Awards of Medals, 1945 The Copley Medal is awarded to Dr Oswald Theodore Avery for his contributions to knowledge of the chemical basis of the specific properties of bacteria, particularly of the types of the pneumococcus. His researches in this field have appeared in unhurried and orderly sequence over the course of a long and distinguished career, and they have furnished a large and essential constituent of the framework now available for a fundamental science of immunochemistry.
