Sophie Frederikke Louise Charlotte Reventlow née von Beulwitz or von Beulwiz (1747–1822) was a Danish countess, author and letter writer. She contributed to improvements in children's education and upbringing and, encouraged by her husband, the statesman Christian Ditlev Frederik Reventlow, published an account of her children's upbringing in Vore opblomstrende Børn (Our Flourishing Children) which she had compiled as her large family developed in the 1770s and 1780s. Her correspondence, which has been preserved, reveals much about her concerns and feelings.[1][2][3]
