Notes
a. Note:   Edwin Henry Colpitts was a communications pioneer best known for his invention of the Colpitts oscillator. He began his education at Mount Allison University and was later a teacher and school principal in Newfoundland. In 1895 he entered Harvard University where he studied physics and mathematics. He received a BA in 1896 and a Master's degree in 1897 from that institution.
  In 1899 he accepted a position with American Bell Telephone Company, and moved to Western Electric in 1907. As research branch chief for Western Electric in the early 1900s, he and scientists under his direction achieved significant advances in the development of oscillators and vacuum tube push-pull amplifiers. In 1915, his team successfully demonstrated the first transatlantic radio telephone. In 1915, Colpitts improved on the inductive coupling oscillator invented by Ralph Hartley. He patented it as the "Oscillation Generator" in 1920. Western Electric research laboratories became part of Bell Laboratories in 1925. Colpitts reached the position of vice-president of Bell Labs before retirement.
  Colpitts served in the US Army Signal Corps during World War I and spent some time in France as a staff officer concerned with military communication. He worked on US government committees working on sonar in the Second World War. [Source: http://en.wikipedia.org/wiki/Edwin_H._Colpitts]
