Nothing—not even the chance to live—makes Dr. Korczak abandon the children of the Warsaw Ghetto. This profoundly moving illustrated book is based on the true story of the celebrated Polish educator, writer, and doctor Janusz Korczak. His works inspired the Universal Declaration of the Rights of the Child, which was adopted by the UN in 1959. With mood-setting artwork and lyrical text, Mister Doctor allows young readers to meet the remarkable man whose humanity and bravery still stand as a glimmer of light in one of history’s darkest periods.
