Abdul Qadeer Khan
Updated: Wikipedia source
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 network selling to Iran, North Korea, Libya, and others, handed to them by the Bush administration of the United States. Khan admitted his role in running this network – only to retract his statements in later years when he levelled accusations at the former administration of Pakistan's Prime Minister Benazir Bhutto in 1990, and also directed allegations at President Musharraf over the controversy in 2008. Khan was accused of selling nuclear secrets illegally and was put under house arrest in 2004. After years of house arrest, Khan successfully filed a lawsuit against the Government of Pakistan at the Islamabad High Court whose verdict declared his debriefing unconstitutional and freed him from house arrest on 6 February 2009. The United States reacted negatively to the verdict and the Obama administration issued an official statement warning that Khan still remained a "serious proliferation risk". On account of the knowledge of nuclear espionage by Khan and his contribution to nuclear proliferation throughout the world post-1970s, and the renewed fear of weapons of mass destruction in the hands of terrorists after the September 11 attacks, former CIA Director George Tenet described Khan as "at least as dangerous as Osama bin Laden". After his death on 10 October 2021, he was given a state funeral at Faisal Mosque before being buried at the H-8 graveyard in Islamabad.
