Israel Albert Horowitz (often known as I. A. Horowitz or Al Horowitz) (November 15, 1907 – January 18, 1973) was an American International Master of chess. He is most remembered today for the books he wrote about chess. In 1989 he was inducted into the US Chess Hall of Fame.^[1]

Horowitz was the chess columnist for The New York Times, writing three columns a week for ten years. He was the owner and editor of Chess Review magazine from 1933 until it was bought out and taken over by the United States Chess Federation in 1969 and merged into Chess Life. Chess Review magazine was founded in 1933 as a partnership between Horowitz and Isaac Kashdan; however, Kashdan dropped out after just a few issues and Horowitz became sole owner. Before that, Horowitz had been a securities trader on Wall Street. He had been partners with chess masters Maurice Shapiro, Mickey Pauley, Albert Pinkus and Maurice Wertheim. Horowitz dropped out and devoted himself to chess, while the others stayed on Wall Street.

Horowitz was a leading player in the U.S. during the 1930s and 1940s. He was U.S. Open Champion in 1936, 1938, and 1943. In 1941, he lost a match (+0−3=13) with Samuel Reshevsky for the U.S. Chess Championship. He played on the U.S. Team in four Chess Olympiads, in 1931, 1935, 1937, and 1950; the first three of which were won by the U.S. In the famous US vs. USSR radio chess match 1945, Horowitz scored one of the only two wins for the U.S. by defeating GM Salo Flohr. He split his "mini-match" of two games against Flohr, and in the 1946 edition of the same event, split his mini-match against Isaac Boleslavsky.

In his book Modern Ideas In The Chess Openings, Horowitz proposed a defense against the Danish Gambit (1.e4 e5 2.d4 exd4 3.c3 dxc3 4.Bc4 cxb2 5.Bxb2). Rather than play the usual 5...d5, Horowitz suggested keeping both pawns and playing 5...c6. This would be followed up by ...d6, ...Nd7, ...Nc5, and ...Be6. Although infrequently played, the defense has not been refuted. Horowitz is credited as the inventor of the defense; it is called Horowitz Defense by GM Nigel Davies in the Foxy Openings DVD Dashing Danish.
