Mohamed Atta
Atta was born in 1968 in a small town in Egypt's Nile Delta. He was 10 years old when he moved with his family to the Abdeen section of Cairo. Atta studied architecture at Cairo University, graduating in 1990, and continued his studies in Germany at the Hamburg University of Technology. In Hamburg, Atta became involved with the al-Quds Mosque, where he met Marwan al-Shehhi, Ramzi bin al-Shibh, and Ziad Jarrah, together forming the Hamburg cell. Atta disappeared from Germany for periods of time, spending some time in Afghanistan, including several months in late 1999 and early 2000 when he met Osama bin Laden and other top al-Qaeda leaders. Atta and the other Hamburg cell members were recruited by bin Laden and Khalid Sheikh Mohammed for the "planes operation" in the United States. Atta returned to Hamburg in February 2000, and began inquiring about flight training in the United States.
Muammar Gaddafi
Muammar Mohammed Abu Minyar Gaddafi was born in a tent, near Qasr Abu Hadi, a rural area outside the town of Sirte in the deserts of Tripolitania, western Libya. His family came from a small, relatively uninfluential tribal group called the Qadhadhfa, who were Arabized Berber in heritage. His mother was named Aisha (died 1978), and his father, Mohammad Abdul Salam bin Hamed bin Mohammad, was known as Abu Meniar (died 1985); the latter earned a meagre subsistence as a goat and camel herder. Nomadic Bedouins were illiterate and kept no birth records. As such, Gaddafi's date of birth is not known with certainty, and sources have set it in 1942 or in the spring of 1943, although his biographers David Blundy and Andrew Lycett noted that it could have been pre-1940. His parents' only surviving son, he had three older sisters. Gaddafi's upbringing in Bedouin culture influenced his personal tastes for the rest of his life; he preferred the desert over the city and would retreat there to meditate.
