NEWS University of Wisconsin and earned his M.S. in 1948 and his Ph.D. degree in 1950. Dr. Malmstadt joined the faculty at the University of Illinois in 1951, and he was promoted to Pro­ fessor of Analytical Chemistry in 1961. Dr. Malmstadt has contributed to analytical chemistry by the develop­ ment, in conjunction with the Ε. Η. Sargent Co., of automatic titrimeters. lie also developed a graduate course "Klectronics in Analytical Instrumen­ tation" which was described in ANA­ LYTICAL CHEMISTRY, Feb., 1961.

Professor Malmstadt was awarded a Guggenheim Fellowship in 1960, at which time he investigated spectro­ scopic laboratories in Europe. He has authored or eoauthored 58 technical papers, and has written a book "Elec­ tronics for Scientists" published in June of this year by W. A. Benjamin, Inc.

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.
