Alexander Dallas Bache
Alexander Dallas Bache (July 19, 1806 – February 17, 1867) was an American physicist, scientist, and surveyor who erected coastal fortifications and conducted a detailed survey to map the mideastern United States coastline.Originally an army engineer, he later became Superintendent of the United States Coast Survey, and built it into the foremost scientific institution in the country before the American Civil War.[1] Whereas Hassler had faced continual doubts from Congress, Bache succeeded in convincing legislators of the value of geodesy in addition to geomagnetic and meteorological research.[1] With many contacts, friends, and family among the nation's political and military leaders, Bache won liberal appropriations to build up his agency and greatly expand its work.A number of trusted friends and Democratic allies, including senators Jefferson Davis and Stephen Mallory, would lead the rebellion — acts that Bache took as both political and personal treachery.Meanwhile, Bache continued to lead scientists to greater influence in government, helping to establish the U.S. Sanitary Commission and National Academy of Sciences.
