Although best known as the inventor of the telephone, Dr. Alexander Graham Bell (1847-1922) expressed an interest in a wide range of activities, including aviation. By the turn of the 20th century he was experimenting with kites and kite structures, including his famous tetrahedral kite "Cygnus," which carried a man aloft in 1907 and was intended to be fitted with a motor. Bell supported the experiments of Samuel Langley from 1891 on, and had some influence in obtaining War Department funding for Langley's aeronautical work. After the successful flight of the Wright Brothers in 1903 he formed, with Glenn H. Curtiss, F. W. Baldwin, J. A. D. McCurdy, and Lt. T. Selfridge, the Aerial Experimental Association, which experimented with a number of flying machines before the founders dissolved the group in 1909. Bell's contributions to aeronautics are reflected in his being issued nine patents for various advances in "aerial vehicles" and "flying machines."
