During his first seven years, Frederick lived with his mother and older sister Wilhelmine. Frederick and Wilhelmine formed a close relationship at this time, which lasted until her death in 1758. Frederick was brought up by Huguenot governesses and tutors and learned French and German simultaneously. In spite of his father's desire that his education be entirely religious and pragmatic, the young Frederick, with the help of his tutor Jacques Duhan, procured for himself a three thousand volume secret library of poetry, Greek and Roman classics, and French philosophy to supplement his official lessons.
