Invincible Louisa is a biography by Cornelia Meigs that won the Newbery Medal and the Lewis Carroll Shelf Award.

Meigs portrays Bronson Alcott and the oldest daughter, Anna, as being fully committed to the ideals of this new life, but says that Louisa and her mother understand how much hard work would be necessary for a communal farm to succeed.

The contrast between idealistic and practical is shown when Bronson and the only other adult leave the area for a conference just as the barley is being harvested.

Besides presenting the facts of her life, the author weaves in many evocative descriptions of Louisa's environment and feelings, thus creating a biography that seems more interesting and appealing than a more factual, unadorned work.

It went on to praise "the new biography, which makes Joe (sic) live again in the courageous, gallant girlhood of this favorite of American story tellers.
