Berl Feldmann (later Amir Gilboa) was born to a Jewish family in Radziwillow (now Radyvyliv, Volhynia) in Ukraine.

He died in 1984 at Beilinson Hospital in Petah Tikva due to complications from ischemic heart disease.

In 1949, he published a volume of poetry entitled Sheva Reshuyot ("Seven Domains") about his war-time experiences.

This collection, along with his Early Morning Songs, published in 1953, established his reputation as a leading Hebrew poet.

His early work was influenced by Avraham Shlonsky and Natan Alterman, especially in its use of archaic, biblical Hebrew.
