MARTINEAU, Harriet (1802–1876), writer, journalist and sociologist. Autograph letter signed to an unnamed correspondent (“Dear Friend”) in light blue ink, 8vo., no place, no date (headed “saty morng”), inviting a friend to dine “Mrs Porter will be most happy to see you, they bid me say come early & we will have a walk on the Heath”, and closes giving directions to the Porters’ house on Putney Heath. Gum line mark on reverse just showing through left front margin, and later ink inscription by a collector (?) “Miss Harriet Martineau” at the letter head.
Harriet Martineau wrote 35 books and a multitude of articles from a sociological, holistic, religious, domestic, and a feminine perspective and translated various works from Auguste Comte, making a living supported entirely by her writing. Martineau introduced feminist sociological perspectives in her writing on issues such as marriage, children, domestic and religious life, and race relations. The novelist Margaret Oliphant said "as a born lecturer and politician she was less distinctively affected by her sex than perhaps any other, male or female, of her generation." (Wikipedia).
Her friends the Porters were George Richardson Porter (1792–1852), civil servant and statistician, and his wife Sarah Ricardo Porter (1790–1862) a writer on education, who lived for a time on Putney Heath. (See ODNB).
