Wikipedia:Articles for deletion/Leland Smith
Smith single-handedly developed what is arguably the best music typesetting program SCORE (software), and warranted a three page obituary in a major academic journal.  A Google on 'Leland Smith SCORE' brings up a non-trivial amount of notable mentions, as it does Google Books (per |BEFORE).  I consider these to satisfy the notability guidelines
