Charles H. Moore

Charles Havice Moore II (born 9 September 1938), better known as Chuck Moore, is an American computer engineer and programmer, best known for inventing the Forth programming language in 1968. He cofounded FORTH, Inc., with Elizabeth Rather in 1971 and continued to evolve the language with an emphasis on simplicity. Beginning in the early 1980s, he shifted focus to designing stack machines in hardware conjoined with Forth-like languages to run on them. He developed the Novix NC4000 and Sh-Boom, then the minimal instruction set MuP21, and i21. In the 2000s he created a series of low-power chips containing up to 144 individual stack processors. He has implemented his own tools for processor design.
