Jacob Friedrich von Abel (9 May 1751 – 7 July 1829) was a German philosopher. His main interest was the human soul and in trying to find a proof for its immortality. Born in Vaihingen an der Enz, von Abel studied philology, philosophy and theology in the lower seminaries in Denkendorf and Maulbronn and in the higher seminary in Tübingen. He graduated in 1770 and was appointed professor of philosophy at the Militär-Pflanzschule at the Solitude Palace which moved later to Stuttgart. While there, he was one of Schiller's teachers and a good friend (becoming the dedicatee of his second play, Fiesco).
