Lee, Gary,
Also known as a "modified Pierce" as opposed to the original circuit
where the crystal was connected between the grid and the plate of the
oscillator tube. Invented by Prof. G. W. Pierce of Harvard University
in 1923 and probably used more over the years than any other crystal
oscillator circuit.
