 Johann Heinrich Pestalozzi (1746-1827) was a Swiss educator, a pioneer of modern education, known for his child-centered educational methods.
 Although Pestalozzi did not use photography, his pedagogical principles influenced its later use in education, facilitating learning through experience and direct observation.
 Pestalozzi stereo cards offer series featuring landscapes, trades, or skills intended for the education of young children.
