Abigail "Abba" Alcott was an American activist for several causes and one of the first paid social workers in the state of Massachusetts. She was the wife of transcendentalist Amos Bronson Alcott and mother of four daughters, including Civil War novelist Louisa May Alcott.

Amos Bronson Alcott was an American teacher, writer, philosopher, and reformer. As an educator, Alcott pioneered new ways of interacting with young students, focusing on a conversational style, and avoided traditional punishment. He hoped to perfect the human spirit and, to that end, advocated a plant-based diet. He was also an abolitionist and an advocate for women's rights.
