Edmond I Eger II 1930- 2017

Edmond Eger was born in Chicago, when Al Capone was at his worst.  He was maturated at Illinois and trained as a anaesthetist at St Luke's.
He moved about the country with the Army and joined the University of California in 1960.
Dr. Eger devised a method working with Dr. Giles Merkel, Dr. Lawrence Saidman and other anesthesiologists at the University of California, San Francisco. They identified one value to use as a benchmark: the concentration of anesthesia at which 50 percent of patients did not move in response to a painful stimulus, like being cut with a scalpel.
Other patients would require a slightly higher or lower concentration to achieve the same effect, but the variations were not large.
That led to their introduction in 1965 of a concept, called the minimum alveolar concentration, or MAC, that quickly became the standard measure of potency for anesthetic gases.328
Eger has given the Anaesthetic profession the Minimum Alveolar Concentration or MAC for short.
This gives the anaesthetist a guide to Anaesthetic depth.329
 He died of pancreatic cancer on Aug. 26 2017 at his home in Tiburon, California. He was 86.
