Miriam Halfi (from the Sternbaum family) was born in Sokolow (Poland). Her father, Barukh, was a merchant. Her mother, Rachel was born initially into the Salzberg family.
Halfi grew up in a traditional, Zionist household.
Her father was a Maskil and taught her Hebrew in her youth. In 1925, she moved to the Land of Israel with her father (though her mother had died in Poland by this point).
In Palestine she studied in a night high school, Gymnasia Humanista, and she studied in a course for kindergarten teachers.
She, with her family, lived in Tel Aviv. After her studies, she worked as a teacher and a kindergarten teacher in special education. In 1952, the couple was sent to Mexico to teach in the Tarbut/Cultura school system wherein she established a Hebrew kindergarten.
There, she completed, with great notability, sculptural studies in Louisiana Academía del Arte in Mexico City.
When she returned to Israel, she continued in her sculptural studies with Rudy Lehmann and Dov Feigin. She died in Tel Aviv in 2002.
