Jack Tramiel was a pioneering microcomputer CEO who co-founded Commodore and later saved Atari. He was born in Poland in 1929 and survived the Holocaust as a child, witnessing atrocities. After immigrating to the US, he started his own typewriter business and later expanded into calculators and microcomputers. He helped popularize home computing through Commodore's PET and Commodore 64 models, selling over 20 million units. Though he had a ruthless management style, he played a key role in bringing computing to the masses. Tramiel passed away in 2012 and his legacy includes making computing accessible and helping launch entire industries.
