Muhammad Naguib
Seddik graduated from Military Academy in 1933. He was active in the 1948 Palestine War. He joined the ranks of the underground Free Officers Movement in 1951, becoming its most senior member after Muhammad Naguib, and was a lieutenant-colonel of the infantry by 1952. Seddik had been a member of a Communist organisation, the Democratic Movement for National Liberation (DMNL), when the Free Officers requested his membership.
