E. Bright Wilson, J r . , Harvard, lines the medalist's scientific
out work
According t o Dr. Pauling, the structure of proteins and t h e origin of the specific properties of biological substances are the most important immediate problems in the field of organic and biological chemistry. The speaker expressed t h e belief that the specificity of antigens and antibodies, of enzymes, and of genes will all be found due to the same modes of physical-chemical interaction between molecules. Immuno chemical evidence, Professor Pauling said, strongly supports the concept that this biological specificity depends on a complementarinessin structure of large molecules and that the specific forces function only when the complementary structures are in close contact with one another. In his address o n the scientific work of the medalist that preceded the medal award, Dr. Wilson emphasized the ex treme versatility and range of interest of Professor Pauling. Reference was made to the medalist's work in the study of crystal structure by the use of x-rays, his application of quan tum mechanics t o atomic and molecular structure, particularly with respect to the theory of valence, his use of the diffraction of electrons for the study of the structure of gaseous molecules, h i s wartime work in the chemistry of propellants, and his many contributions to the knowledge of proteins and antibodies. Dr. Baker's preface t o his presentation of the medal t o Dr. Pauling consisted of a short history of previous Richards medal awards to several distinguished scientists. Dr. Baker listed these i n order of date as Theodore William Richards (posthu mously), Arthur A . Xoyes, Gregory Paul Baxter, Charles August Kraus, Gilbert Newton Lewis, Claude Gilbert Hudson, Frederick George Keyes, and Roger Adams. VOLUME
