N. Howell FurmanDied 2 Aug 1965 at age 73 (born 22 Jun 1892).American analytical chemist whose analytical separation of uranium contributed to the development of the atomic bomb. He developed special techniques for preparing the bomb project materials, notably the sampling and analysis necessary for producing pure uranium metal. He also devised a new method of estimating traces of metals in various substances and assisted in developing an ether extraction process for the preparation of uranium oxide of the extreme purity required. His special methods also made possible greater utilization of tracer techniques with radioactive and stable isotopes. |
