Hester Lynch Thrale Piozzi, a Welsh-born diarist, author and patron of the arts, is an important source on Samuel Johnson and 18th-century English life. She belonged to the prominent Salusbury family, Anglo-Welsh landowners, and married first a wealthy brewer, Henry Thrale, then a music teacher, Gabriel Mario Piozzi. Her Anecdotes of the Late Samuel Johnson (1786) and her diary Thraliana, published posthumously in 1942, are the main works for which she is remembered. She also wrote a popular history book, a travel book, and a dictionary. She has been seen as a protofeminist.
