Damaris Cudworth, Lady Masham was an English writer, philosopher, theologian, and advocate for women's education who is often characterized as a proto-feminist. She overcame some weakness of eyesight and lack of access to formal higher education to win high regard among eminent thinkers of her time. With an extensive correspondence, she published two works, A Discourse Concerning the Love of God (1696) and Thoughts in reference to a Vertuous or Christian Life (1705). She is particularly noted for her long, mutually-influential friendship with the philosopher John Locke.
