1811–1892
Raised in a family of teachers and shaped by the educational ideas of Pestalozzi, this 19th-century German school reformer wrote widely on teaching, language, and moral education. His books helped define elementary schooling in Catholic Prussia and kept his name alive well beyond the classroom.

by Lorenz Kellner
Born on January 29, 1811, in Kalteneber in the Eichsfeld region, Lorenz Kellner was the son of Heinrich Kellner, a teacher influenced by Johann Heinrich Pestalozzi. He studied at the Gymnasium Josephinum in Hildesheim and then at the teachers' seminary in Magdeburg, before beginning his own career in education.
Kellner taught in Erfurt, later served as a seminar director in several cities, and eventually became a school councillor in Trier. He was known as an important Catholic educator in 19th-century Prussia, with a strong interest in improving elementary teaching and teacher training.
He also wrote extensively. Among his best-known works are books on pedagogy, language teaching, and popular education, including Aphorisms on Education and a widely used reader for schools. He died in Trier on August 18, 1892, remembered chiefly for helping shape practical classroom education for teachers and children alike.
