Tagger's family originated from Sepheradi Jews from Spain which moved to the Netherlands in the 15th century and later to Germany and Bulgaria.

Tagger pursued her studies at Bezalel from 1921 to 1922, and upon completion, she made the decision to travel to Paris, despite renewed objections from her parents.

Art consistently remained Tagger's foremost priority, even after her marriage to Michel-Mordechai Katz in 1933, the birth of her son Abraham Katz-Oz in 1934 (who would later become a Knesset member and Israel's Minister of Agriculture), and subsequent divorce.

She cited her separation from her husband, explaining that he couldn't accept the extensive hours she dedicated to her art, often neglecting meal preparation.

During the 1920s, Tagger, along with other "modernist" artists, mostly of the Histadrut art Studio and former pupils of Isaac Frenkel and Joseph Constant, predominantly based in Tel Aviv, diverged from the Romantic Orientalist tradition prevalent in Bezalel's landscapes and figure paintings.

The portrayal of rustic Arabs or Yemenites representing the ancient Jewish inhabitants of the land gave way to depictions of pioneers, writers, poets, and present-day public figures.
