Steven James Edwards, (February 7, 1957 - October 1, 2016 [1])
was an American computer scientist, BS and MS in Mathematics, and computer chess programmer. Steven Edwards coordinated and specified the PGN- and EPD-standards and the FEN-Position Description [2]. In 1994 he introduced a distance to mate endgame tablebase format, called the Edwards' Tablebases. He is author of multiple chess programs and toolkits, Spector, Symbolic, the Chess in Lisp (CIL) package [3] [4], a portable ChessLisp interpreter [5], and the Chess for Arduino Mega Myopic [6] and the Chess in Pascal CookieCat [7] projects [8]. Steven Edwards has been actively involved in Perft computations, where he computed and verified perft of the initial position up to a depth of 13, now available in the On-Line Encyclopedia of Integer Sequences [9] .

Steven Edwards died on October 1, 2016 at age 59 at his home in Raymond, New Hampshire, only a few weeks after his father James Edwards passed away [10], who introduced him to chess [11].
