Recruited by
Wallace C. Abbott, Volwiler joined Abbott Laboratories as a research
chemist in 1918.
Nembutal Volwiler was a pioneer in the field of
anesthetic pharmacology, assisting in the development of two breakthrough drugs, the
barbiturates Nembutal and
Pentothal. Nembutal, developed by Ernest H. Volwiler and Donalee L. Tabern of Abbott Laboratories in 1930, was a novel barbiturate that could induce sleep within 20 minutes. It had the advantage of rarely producing hangovers or other side effects. An oral-hypnotic barbiturate, Nembutal has a long narcotic duration, with attendant risk of abuse. In the mid 1930s, Volwiler and Tabern spent three years screening over 200 candidate compounds in search of a substance which could be injected directly into the blood stream to produce unconsciousness. They eventually discovered that 5-ethyl-5-(1-methylbutyl)-2-thiobarbituric acid, a sulfur-bearing analogue of Nembutal, was fast, effective and lacked side effects such as twitching or delirium. Volwiler and Tabern were awarded U.S. Patent No. 2,153,729 in 1939 for the discovery of thiopental. Pentothal's discovery revolutionized intravenous anesthesia. Abbott was one of five companies enlisted in 1941 by the U. S. government to develop penicillin.
Wartime Intelligence At the end of
World War II, Volwiler was asked to visit German chemistry facilities on an intelligence mission to assess the types and extent of Germans chemical technology. Following just days after the Allied troops, he viewed bombed industrial facilities and talked to German scientists. Volwiler did not find the scientists difficult to speak with, remembering "Oh, they were scared to death and they were very cooperative." The visit yielded important information, previously unknown, about the types of chemicals being used in German chemical warfare. the treatment of
epilepsy, and the development of the non-caloric sweetener
Sucaryl for use in
diabetic diets. He retired in 1961. From 1958 to 1964, Volwiler served a six-year term on the
National Science Board, appointed by President
Dwight D. Eisenhower. The NSB is the 24-member governing board of the
National Science Foundation. ==Philanthropy==
