Cohn worked with development of radioiso tope production and distribution meth ods which culminated in the general distribution of radioisotopes produced in the Oak Ridge reactor. H e also in vestigated the ion exchange chromatog raphy of fission products, which re sulted in the first separation of the rare earths b y this method, leading to the first isolation of element 61. Since 1948 D r . Cohn, as a Senior Biochemist with O R N L , has concentrated on in vestigations of nucleic acid structure, chemistry and enzymology. D r . Cohn pioneered in ion exchange c h r o m a t o graphic methods for biochemistry. H e is a u t h o r or coauthor of more t h a n 60 publications. D r .

1962 Harvey W . W i l e y Award Milton S. Schechter of the Agricul tural Research Service, II. S. Dept. of Agriculture, has been selected to receive the 1962 Harvey W. Wiley Award of the Association of Official Agricultural Chemists. Mr. Schechter was chosen for his numerous brilliant contributions to the development of analytical methods for insecticides and their residues and for his outstanding accomplishments in the development of new insecticides during his 25 years of service with the Dept. of Agriculture. Many of his contribu tions have achieved world recognition, particularly the standard "SchechterHaller" colorimetric method for DDT residues, the colorimetric method for residues of benzene hexachloride, and the development of a general route for the synthesis of pyrethrin-like insecticidal esters such as allethrin. Mr. Schechter is in charge of the project on the development of analyti cal methods for insecticides and their residues for the Pesticide Chemicals Research Division, of the Agricultural Research Service. The Harvey W. Wiley Award was established in 1956 by the AOAC in honor of the founder of the original Food and Drug law and of the AOAC, and is given annually to a scientist who has made an outstanding contribution to the development of methods for the analysis of food, drugs, cosmetics, feeds, fertilizers, or pesticides, or for use in general analytical chemistry. The Award of $500 is presented at the Asso ciation's meeting in the fall.
