Sarah Trimmer was an experienced Sunday and charity school educator, remembered for her popularization of images and fables in children’s textbooks. Trimmer’s ideas were already well respected during her lifetime and many of her books saw multiple editions, eliciting the interest of such figures as Queen Charlotte and the Dowager Countess Spencer. Her Reflections upon the Education of Children in Charity Schools, first published in 1792, was one of several books she wrote to advise her readers on how to approach the Christian education of the poor. In it, Trimmer passionately advocated for the utility of charity schools, provided that they followed a more age-appropriate and critical curriculum, which she conveniently published as separate editions. Those interested in the history of education, social history, the Society for the Propagation of Christian Knowledge, or the changing voice of female authorship will benefit from this book.
