Entezam was born into middle-class family in Tehran in 1933. He studied electro mechanical engineering at University of Tehran and graduated in 1955.
In 1956, Entezam left Iran for study at A.S.T.E.F. Institute (Paris). He then went to the U.S. and completed his postgraduate education at the University of California in Berkeley.
After graduation, he remained in the US and worked as an entrepreneur.
Around 1970 Entezam's mother was dying and he returned to Iran to be with her. Because of his earlier political activities, the Shah's Intelligence Service would not allow him to return to the U.S. He stayed in Iran, marrying, becoming a father and developing a business in partnership with his friend and mentor, Mehdi Bazargan. Bazargan appointed him as the head of political bureau of the Freedom Movement of Iran in December 1978, replacing Mohammad Tavasoli. In 1979, the Shah was overthrown by the Iranian Revolution. Revolutionary leader Ayatollah Khomeini, recently returned to Iran, appointed Bazargan as prime minister of the provisional revolutionary government. "Bazargan asks Entezam to be the deputy prime minister and the official spokesperson for the new government."
According to Entezam's website:
Following the orders of the Prime Minister, Entezam sets out to rebuild the relationship between the US and the post-revolutionary Iran. He retains diplomatic contacts with the US embassy, advocating for normalization of the relationship between the two countries.
While serving as deputy prime minister in April 1979 Entezam actively advocated the retirement of army officers from the rank of brigadier general. In 1979, Entezam "succeeded in having the majority of the cabinet sign a letter opposing the Assembly of Experts", which was drawing up the new theocratic constitution where democratic bodies were subordinant to clerical bodies. His theocratic opponents attacked him and in August 1979 Bazargan "appointed Entezam to become Iran's ambassador to Denmark."
Bazargan asked Entezam, who had been serving as ambassador to Sweden, to come back quickly to Tehran. After coming back to Tehran, he was arrested in December 1979 because of allegations based on some documents retrieved from U.S. embassy takeover, and received lifetime prison from court. He was released in 1998, but in less than 3 months, he was arrested again because of an interview with Tous daily newspaper, one of the reformist newspapers of the time.
In smuggled letters, Entezam has related that on three separate occasions, he had been taken blindfolded to the execution chamber - once being kept "there two full days while the Imam contemplated his death warrant." He has spent 555 days in solitary confinement, and in cells so "overcrowded that inmates took turns sleeping on the floor - each person rationed to thee hours of sleep every 24 hours." He suffered permanent ear damage, skin disease, and spinal deformities." He has attacked the regime saying
Islam is a religion of care, compassion, and forgiveness. This regime makes it a religion of destruction, death, and torture.
He has always denied all the allegations that have been put against him in his trial and asks for a retrial.Bruno Kreisky Prize (1998)Jan Karski Award for Moral Courage (2003)
