Johann Heinrich Pestalozzi (12 January 1746 – 17 February 1827) was a Swiss pedagogue and educational reformer who exemplified Romanticism in his approach.
He founded several educational institutions both in German and French speaking regions of Switzerland and wrote novels explaining his revolutionary modern principles of education. His motto "Learning by head, hand and heart" is still a key principle in successful 21st century schools. Thanks to Pestalozzi, illiteracy still prevailing in 18th century Switzerland was overcome almost completely by 1830.
