Jacek Trzmiel was born in Lodz in 1928. In 1944 he was deported to Auschwitz concentration camp. The camp was liberated in 1945. Two years later he emigrated to the USA and established Commodore International. In 1977, the first personal computer Commodore PET was built. The later model, Commodore 64 (1982), left behind such giants as Apple and IBM - as many as 17 million computers were sold worldwide. Commodore 64 was entered into the Guinness Book of Records as the best-selling model in the history of computer.
