Simone Marthe Brangier Boas (February 3, 1895 – June 17, 1981) was a French-born American modernist sculptor who spent her career in Baltimore, Maryland.

[1][2] At Berkeley, she met philosophy PhD student George Boas while attending a seminar on The Self; they married in 1921.

She and George Boas were able remain in contact in France as he enlisted as a lieutenant in the US Army and served as aide de camp to General Charles Kilburn.

[1][3] Art historian Charlotte Streifer Rubinstein wrote of Boas' work "Imbued with the "truth to materials" aesthetic, Simone Boas carved massive, stylized heads and figures directly in wood and stone with no openings or penetrations in the forms.

[5] Boas published some translations from the French, including one of Alfred Charles Auguste Foucher's biography of Buddha.
