BUDAPEST, Hungary (AP) _ Tamas Szechy, a Hungarian coach whose swimmers won 15 Olympic medals, died Monday at 73.

Szechy died at his Budapest home of undetermined causes, said Jozsef Ruza, secretary general of the Hungarian Swimming Association.

``He simply fell asleep on his couch, his glasses still on,'' Ruza said.

Szechy was considered Hungary's most successful swim coach. Between 1972 _ when Andras Hargitay won a bronze in the 400-meter medley in Munich _ and the 1996 Atlanta Games, swimmers trained by Szechy won eight Olympic gold medals, four silver and three bronze. In world championships between 1973 and 1998, his swimmers won 21 medals, including 12 golds.

Among the stars trained by Szechy were Tamas Darnyi, winner of four Olympic gold medals, Norbert Rozsa and Attila Czene.

``He demonstrated to all of us that with persistent work and faith, talent prevails even in difficult circumstances,'' Sports Minister Ferenc Gyurcsany said.
