- Description:
- Ralph Gorin for creating the first spelling corrector. The first spelling checker was created at MIT in 1961 by Les Earnest as part of the first cursive handwriting recognizer and used a list of the 10,000 most common English words. In 1967 Earnest recruited a SAIL graduate student to make a spelling checker for text files, which was written in LISP, used a suffix stripping scheme to effectively increase the vocabulary of the word list, and rather slowly produced a list of unrecognized words and their locations in the file. In 1971 Eamest recruited Ralph Gorin to make an interactive spelling checker. Gorin wrote SPELL in machine language, for faster action and made the first spelling corrector by searching the word list for plausible correct spellings that differ by a single letter or adjacent letter transpositions. The program became more useful by allowing each user to extend the dictionary interactively and use those extensions in the future. He made SPELL publicly accessible and it soon spread around the world via the new ARPAnet, about ten years before personal computers came into general use.
