He was the son of Heinrich Kellner who had been a pupil of Pestalozzi at Yverdon and had introduced Pestalozzi"s methods at the normal school he conducted, the first of its kind in the Catholic district of Eichsfeld.
Lorenz Kellner graduated at the Gymnasium Josephinum at Hildesheim, and then studied at the evangelical seminary for teachers at Magdeburg.
Out of these private courses for the training of elementary school-teachers developed a seminary for teachers at Heiligenstadt. After being a teacher at the Catholic elementary school at Erfurt for two years, he was made rector of the school. In 1836 his father"s normal school was enlarged into a seminary for teachers, of which the elder Kellner remained the head while Lorenz was made his only assistant.
After seven years at Marienwerder, Kellner was summoned to fill the same offices at Trier.
Since there were at this date no institutions for the training of teachers in Trier, Kellner founded several seminaries both for male and female teachers during the twenty-nine years of his official activity here. In 1863 the Academy of Münster in Westphalia made Kellner Doctor of Philosophy honoris causa, in recognition of his services on behalf of the German language and of pedagogics.
In 1848 von Eichhorn, the Prussian minister of worship and education, called Lorenz to Marienwerder in West Prussia as member of the government district council and of the school-board.
