Salah Nasr (Arabic: صلاح الدين محمد نصر, IPA: [sˤɑˈlɑːħ edˈdiːn mæˈħammæd ˈnɑsˤɾ]) (8 October 1920 – 5 March 1982) served as head of the Egyptian General Intelligence Directorate from 1957 to 1967. He retired citing health reasons following Egypt's defeat in the 1967 Six-Day War. He was succeeded by Amin Howeidi in the post.
Nasr was arrested and tried soon after the end of his tenure as the head of general intelligence. He was freed when he was granted release by Anwar Sadat in February 1974.
The Free Officers (Arabic: حركة الضباط الأحرار, romanized: Ḥarakat al-dubbāṭ al-ʾaḥrār) were a group of revolutionary Egyptian nationalist officers in the Egyptian Armed Forces and Sudanese Armed Forces that instigated the Egyptian revolution of 1952. Initially started as a small rebellion military cell under Abdel Moneim Abdel Raouf, which included Gamal Abdel Nasser, Hussein Hamouda, Khaled Mohieddin, Kamal el-Din Hussein, Salah Nasr, Abdel Hakim Amer, and Saad Tawfik, it operated as a clandestine movement of junior officers who were veterans of the Palestine War of 1948–1949 as well as earlier nationalist uprisings in Egypt in the 1940s.
The nationally respected Arab-Israeli War veteran Mohamed Naguib joined the Free Officers in 1949. Naguib's hero status, and influence within the army, granted the movement credibility, both within the military and the public at large. He became the official leader of the Free Officers during the turmoil leading up the revolution that toppled King Farouk in 1952. The Movement was succeeded by the Revolutionary Command Council after the overthrow of Farouk that was later succeeded by the Supreme Council of the Armed Forces.
