off in 1932. Word got around the Harvard Medical School that "something was going on about hearing" in the Department of Physiology. The chairman of the ENT Department, Harris P. Mosher, sent one of his brightest young men around to see what was up. He was Moses H. Lurie. Moe and I had met in 1917 on board the S. S. Chicago on our way to France to serve as doctor and ambulance driver respectively. We had not seen each other since, but we became firm buddies again on the spot. I never had done any histology, but Moe knew how. I needed help, and Moe joined the team, WOC (without compensation). I practiced the old business maneuver of taking in a partner to provide an essential asset. Bill Derbyshire, and later S. S. Stevens, (my students) and I had all the fun in the laboratory doing the experiments and Moe did the laborious anatomical follow-up afterwards. (It's a fine system and I have used it ever since.) Fully as important, we were invited to present our results at an American Otological Society meeting. We shot the works and set up a live demonstration in a hotel dining room (in Philadelphia, I think). Bill Derbyshire anesthetized the cat, performed craniotomy, excised part of the cerebellum to expose the eighth nerve, and put an electrode on the round window - all in a serving pantry during dessert. How we dared try this with portable electronics and primitive acoustics I don't know, except that we were young and foolish: but it worked. We demonstrated the difference between cochlear microphonics and action potentials. I may have condensed two episodes into one, but my memory of the sight of that eighth nerve in the hotel pantry is as vivid as any I possess. This performance earned us a place year after year on the programs of the American Otological Society along with other scientists such as Barry Anson, Theodore Bast, Stacy Guild, and Walter Hughson. Dr. Edmund Fowler was one of our strongest and most appreciative supporters, but I don't think he ever knew what some of us called ourselves. Moe and Bill and I and perhaps others referred to ourselves as "the trained seals." We did our acts regularly, and published papers and were very well

fed. The more fortunate trained seals were made Associate Members. Dr. Fowler was one of our trainers, and Moe Lurie and I got quite chummy with him. One year - about 1936 - at the cocktail party before the American Otological Society dinner Moe Lurie, Dr. Fowler and I' were chatting together. Dr. Fowler raised his glass and proposed a surprising toast: "To the quick immediate and total destruction of the entire human race." For many years thereafter we three drank to the same toast at our second martini. There was, however, a lapse of about five years with no toast after the nuclear bombs were dropped on Japan. Somehow it didn't seem funny then, even at a third martini - but we resumed it later as a reminder of the good old days when it was funny. After the War I became deeply involved in problems of design and distribution of audiometers and hearing aids, and was made chairman of the AMA Committee that dealt with such problems. Sure enough, there were E. P. Fowler, Sr., Moe Lurie and several other grand old men. I soon found that the otologists and the hearing aid dealers considered themselves natural enemies. The otologists were the champions of defenseless senior citizens against the hard sell of unscrupulous dealers. Hearing aids were all right for the conductive impairment of otosclerosis or chronic otitis media, but the otologists' conventional wisdom for the elderly was: "You have nerve deafness, and a hearin~ aid won't help you. Save your money!' Unfortunately at that time "nerve deafness" was any hearing loss that showed up by bone conduction, including presbycusis. Otologists were slow to learn that with a soft sell and realistic expectations a hearing aid does help a great many people with old-fashioned nerve deafness. Ot~erwise there woud be no hearing aid busmess now - especially since some of our grand old men with their stapes surgery have taken so much of otosclerosis out of the hearing aid market. .In the same evangelistic spirit we tned to control the advertising claims of the manufacturers. Our committee met with representatives of the manufacturers annually, and carried on a useful dia-
