Tramiel's Commodore International in 1982 released the Commodore 64, a home computer that became one of the most popular models of all time, selling close to 17 million units between 1982 and 1994.

Tramiel was born in Lodz, Poland, in 1928 to a Jewish family. He survived the Auschwitz concentration camp, after which he emigrated to the U.S. in 1947.

Tramiel claimed that after surviving the Holocaust he could survive just about anything. The Auschwitz survivor undoubtedly survived the computer industry, including being ousted as chief executive officer (CEO) of the company he established. His Commodore Business Machines International grew from a small Canadian company manufacturing typewriters and adding machines to producing electronic calculators to developing computers. Tramiel's first introduction to typewriters came after he joined the U.S. Army in 1948 and was assigned to repairing typewriters in New York area offices. He moved to Toronto in 1955 and founded Commodore Business Machines after realizing the Canadian law would allow him to exclusively import Italian typewriters. The company advanced from typewriter importing to manufacturing the devices and adding machines. Tramiel embraced the burgeoning electronics movement and moved in the late 1960s to Silicon Valley, where Commodore began manufacturing electronic calculators. The company's success almost forced its demise. Texas Instruments, which supplied Commodore with semiconductor chips for its calculators, began manufacturing its own calculators and selling the models at prices Commodore could not match.

Never wanting to be held hostage by a vendor again, Tramiel purchased chip manufacturer MOS Technology to supply Commodore with the needed parts. Tramiel shut down most of MOS' research and development projects, but allowed the microcomputer project to continue.The project produced PET, Personal Electronic Transactor. PET helped Commodore earn US$700 million in sales in fiscal 1983 and $88 million in profits.In 1984, as the company's profits approached $1 billion, Tramiel butted heads with a stockholder and was fired as CEO. Tramiel purchased Atari Corp. from Time Warner Communications later that year. However the company, despite some financial success, never steadily operated in the black and Tramiel sold Atari to JTS, a disk-drive manufacturer he helped fund, but he did not hold any operational role.
