1811–1892
A major Catholic educator in 19th-century Germany, he spent his life improving teacher training and elementary schooling. His practical books on education were widely read and helped shape classroom life well beyond his own time.

by Lorenz Kellner
Born in Kalteneber on January 29, 1811, Lorenz Kellner grew up in a family devoted to education. His father, Heinrich Kellner, had studied with Johann Heinrich Pestalozzi and brought those teaching ideas into Catholic teacher training in Eichsfeld, giving Lorenz an early grounding in reform-minded schooling.
Kellner worked as a teacher and later as a school leader in Erfurt before joining the teachers' seminary at Heiligenstadt, where he eventually became director. He became known as an influential German educator, especially in Catholic circles, and wrote a number of practical works on pedagogy and school life.
Later in life he served in Trier as a school councillor, continuing to advocate for better education and teacher preparation. He died there on August 18, 1892, remembered as a prominent voice in 19th-century elementary education and as a writer whose ideas reached a wide audience.
