STOCKHOLM, Sweden (AP) _ Albert Bonnier Jr., the head of a family empire that has dominated Sweden's newspaper and publishing businesses for decades, died Saturday, a news agency reported. He was 81.

The report by the Swedish national news agency TT said Bonnier died after an unspecified illness. It did not say where he died or give a cause of death.

In the early 1950s, Bonnier founded AB Bonnierforetagen, a diversified, international company. He served as managing director from 1959 to 1981 and chairman of the board until January, when his younger brother Lukas took over.

Albert Bonnier saw himself mainly as a publisher and was chairman of the board at the Bonnier-controlled publishing house Ahlen & Akerlund until 1982.

The Bonnier family also has major holdings in Sweden's major morning paper the Dagens Nyheter, where Bonnier was chairman of the board for years, and the widest circulated daily in Scandinavia, the evening paper Expressen.

The family's tradition in publishing stretches back to 1837 when the publishing house Albert Bonnier's Forlag was founded.
