Fereydoon Moshiri was born in September 1926 in Tehran to a family that was known to have a legacy of poetry. His school years were divided between Tehran and Mashhad where his father held administrative posts.

With the outbreak of the world war II the family moved to Tehran and the young Moshiri continued his education in Dar-ol-Fonoon and then in Adib high school. Throughout these years his first poems appeared in progressive journals such as Iran-e-Ma. This was the beginning of a career in literary journalism that continued for more than thirty years. In 1946 Moshiri joined the Iranian department of Telecommunication where he served till retirement. In 1954 Moshiri married Eghbal Akhavan, then a student painting at Tehran University. Their daughter and son, Bahar and Babak both are now architects in Iran.

Moshiri's first volume of poetry titled "Teshne-ye Toofan" (Thirsty for the Storm) was published in 1955. His poems with its earthy lyrical nature received wide attention among the readers, and had an inspiring effect on a generation of younger poets. Through the later years, Moshiri continued to have a major influence on development of modern poetry in Iran.

Later works which were published under the titles "Abr-o-Koocheh" (Cloud and The Alley, 1962), and "Bahar Ra Bavar Kon" (Believe The Spring, 1967) embraced a wide variety of universal concepts ranging from humanistic considerations to social justice.

Moshiri is best known as conciliator of classical Persian poetry at one side with the New Poetry initiated by Nima Yooshij at the other side. One of the major contributions of Moshiri's poetry, according to some observers, is the broadening of the social and geographical scope of modern Persian literature.
