Mary Anne Schimmelpenninck (née Galton, 25 November 1778 – 29 August 1856) was a British writer in the anti-slavery movement.

Born at Birmingham, she was eldest child of Samuel "John" Galton and his wife, Lucy Barclay.

There among their frequent visitors were James Watt, Richard Lovell Edgeworth, Thomas Day, Joseph Priestley, Samuel Parr, and Erasmus Darwin whose daughter Violetta married Mary Anne's eldest brother, Samuel Tertius Galton.

Mrs. Schimmelpenninck took part in local charities and education, holding classes for young people at her own house.

In 1813 she published a compilation based on one of those volumes, Narrative of a Tour to La Grande Chartreuse and Alet, by Dom.

[2] Schimmelpenninck had prepared the phrenology report used in the prosecution of accused murderer John Horwood in 1821.

She also studied Hebrew with Mrs. Richard Smith, "her more than sister for forty-three years", and embodied the result in Biblical Fragments, 1821–2, 2 vols.
