"When I approach a child, he inspires in me two sentiments; tenderness for what he is, and respect for what he may become." (Louis Pasteur). The book's author, Janusz Korczak, a Polish writer and teacher, believed that children should know life stories of people like Louis Pasteur, whose passion for science led him to great discoveries. The original illustrations were exhibited at Musee Pasteur in Dole, France, on March-June 2013.
