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.

At the Hamburg University of Technology, Atta studied under the guidance of the department chair, Dittmar Machule, who specialized in the Middle East. Atta was concerned about modern development and the construction of high-rise buildings in Cairo and other ancient cities in the Middle East. He believed that the large, impersonal, and often ugly apartment blocks built in the 1960s and 1970s had ruined old neighborhoods, and took away privacy and dignity from people. Atta's own family moved into such an apartment block in 1990, which to him was "a shabby symbol of Egypt's haphazard attempts to modernize and its shameless embrace of the West." For his thesis, Atta focused his studies on the ancient city of Aleppo in Syria. He explored the history of Aleppo's urban landscapes and the general themes of the conflict between Arab civilization and modernity. Atta criticized how the modern skyscrapers and development projects in Aleppo were disrupting the fabric of that city by blocking community streets and altering the skyline.
