Jack Tramiel, a computer-industry pioneer whose Commodore 64 is widely considered the best-selling personal computer in history, died Sunday in California, his family said. He was 83 years old.

    After leaving Commodore in 1984, Mr. Tramiel acquired Atari from Warner Communications and transformed it from a maker of game consoles into a PC manufacturer.

    A survivor of the Auschwitz concentration camp, Mr. Tramiel moved to the U.S. after World War II. He founded Commodore as a typewriter importer, and in the 1960s manufactured some of the earliest electronic calculators.

    Commodore introduced its first PC in 1977, the same year that competing units the Apple II and TRS-80 were introduced.
