A. Q. Khan, or Abdul Qadeer Khan, is a Pakistani nuclear scientist and metallurgical engineer, widely known for his role in developing Pakistan's nuclear weapons program. Born on April 1, 1936, in Bhopal, India, he later moved to Pakistan after the partition in 1947. Khan became a prominent figure in Pakistan's scientific community and is often referred to as the "father of Pakistan's bomb." In the early 2000s, Khan was implicated in a global nuclear proliferation scandal, accused of sharing nuclear technology with countries like Iran, North Korea, and Libya. In 2004, he publicly confessed to these activities but was later pardoned by then-President Pervez Musharraf. Despite his controversial legacy, Khan remains a significant figure in Pakistan's history.
