Richard Merrill
For the American inventor, engineer, and photographer, see Richard B. Merrill.
Richard Merrill was a Digital Equipment Corporation employee who invented the FOCAL programming language and programmed the first two interpreters for the language in 1968 and 1969, for the PDP-8. He also developed later versions of the interpreter for the PDP-7 and PDP-9, and he was most likely the author of the PDP-11 FOCAL interpreter.
Merrill also designed and programmed the EDIT-8 text editor (using paper-tape).[1]
Merrill is an alumnus of Phillips_Andover preparatory school and MIT.
