American Physiological SocietyIn 1887, the American Physiological Society, the first U.S. national physiology society, wasorganizedin New York City. At the time, there were few physiological laboratories in America, and only a small number of investigators. Seventeen men met at the Physiological Laboratory, College of Physicians and Surgeons, Columbia University. Twenty-eight were named as charter members. Silas Weir Mitchell of Philadelphia presided over the meeting, but declined to be its first president, though he did become the second. The first secretary-treasurer was Henry Newell Martin, a biology professor. The society first published theAmerican Journal of Physiology, on 3 Jan 1898. (A local, unrelated, organization of the same name was founded on 11 Feb 1837 in Boston, Mass.)« |
