Charles H. Moore

Charles Havice Moore II (born September 9, 1938, in McKeesport, Pennsylvania) is an American computer engineer and programmer who invented the Forth programming language in 1968 while working at the National Radio Astronomy Observatory to help control radio telescopes. In 1971 he co-founded Forth Inc with Elizabeth Rather, and through the 1970s adapted Forth to numerous computer architectures. From the early 1980s he shifted toward designing stack machine processors in hardware, including the Novix NC4000, and later through GreenArrays marketed low power chips containing up to 144 individual stack processors. He studied physics at MIT under John McCarthy, earning his bachelor's degree in 1961, and pursued graduate mathematics at Stanford until 1965.
