In 1858 he won a game against Paul Morphy, which led to a match between the two. Despite being given odds of pawn and the move (meaning he started the game with an extra pawn and always moved first), Owen lost the match 6-1, never winning a game.
His performance in the 1862 London tournament, the first international round-robin event (in which each participant plays every other) was more impressive - he finished third, ahead of future world champion Wilhelm Steinitz, and was the only player to win against the tournament winner, Adolf Anderssen.
Owen is the eponym of Owen's Defence, a chess opening he often played (including in his victory over Morphy) characterised by the moves 1.e4 b6 (in algebraic notation).
