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.
Ezra Attiya
Attiya was born on 31 January 1885 (Tu Bishvat 5645 on the Jewish calendar) in Aleppo, Syria, which was then part of the Ottoman Empire. His parents, Yitzchak and Leah, had lost several children in infancy, and before his birth they traveled to the gravesite of the Prophet Ezra to pray that if the child they were expecting was a boy, they would name him Ezra and see that he dedicated himself to a life of Torah. He had one brother, Eliyahu. His father, a respected Aleppo melamed (teacher), was a direct descendant of Rabbi Shem Tov Attiya, a disciple of Rabbi Joseph Caro, author of the Shulchan Aruch.
