Born in Rødby, Denmark, Astrid Noack studied at the Royal Danish Academy of Fine Arts in Copenhagen. She spent significant time in Paris during the 1920s, where she worked in the studio of Moise Kogan and was influenced by the modernist sculpture movement.

Noack is best known for her focus on the human form, often utilizing wood and stone to create expressive, simplified figures. Her work is characterized by a balance between classical tradition and modernist abstraction, reflecting a deep engagement with the physical properties of her materials.

Her legacy is cemented by her inclusion in the Danish Culture Canon, a testament to her enduring impact on Scandinavian sculpture. Her public commissions, such as the statue of Anna Ancher, remain key examples of her ability to capture character and form in public spaces.
