Abdul Qadeer Khan (1936–2021)
Born 1936 CE, died 2021 CE.
Abdul Qadeer Khan (1 April 1936 – 10 October 2021) was a Pakistani nuclear physicist and metallurgical engineer. He is colloquially known as the "father of Pakistan's atomic weapons program". A Muhajir emigrant from India who migrated to Pakistan in 1952, Khan was educated in the metallurgical engineering departments of Western European technical universities where he pioneered studies in phase transitions of metallic alloys, uranium metallurgy, and isotope separation based on gas centrifuges. After learning of India's "Smiling Buddha" nuclear test in 1974, Khan joined his nation's clandestine efforts to develop atomic weapons when he founded the Khan Research Laboratories (KRL) in 1976 and was both its chief scientist and director for many years. In January 2004, Khan was subjected to a debriefing by the Musharraf administration over evidence of nuclear proliferation handed to them by the Bush administration of the United States.
