8 June 1943 Dr. R. Kehoe University of Cincinnati Cincinnati, Ohio. Dear Sir: I am about to start an investigation of lead tetraethyl and other lead alkyls from a toxicological point of view; we will also be concerned with the physical and chemical properties of these com pounds. I contacted the Ethyl Corporation and their representative in San Francisco, Mr. Sievert, advised me to contact you before beginning my work. I would appreciate any references you can offer along with suugestions for our work. We are a Chemical Warfare Service organization and our work is solely for the army. I thank you very much. Very sincerely yours, Master Sergeant Oscar P. Cohen 40th Chemical Laboratory Company 6th IIQ Special Troops II Armored Corps San Jose, California KE' 0009908
