Yonie Wondernose is a 1944 picture book by Marguerite de Angeli, who would later win the Newbery Medal for The Door in the Wall.^[1] Sometimes described as an "Amish Curious George", the book was to win the Caldecott Honor citation. As with many of de Angeli's books, she expressed interest in little-known and prejudged people. This was the second book she wrote about the Amish community, the first being Henner's Lydia.

Described as a "wondernose" because he's so curious, seven-year-old Yonie has to become the man of the house when his parents go away.

Yonie is a boy who was left alone with his grandmother. His father gave him the responsibility of a man, to take care of the animals on the farm, not getting distracted as a "wondernose". The main things he has to do is to supply water and get wood for his grandmother. Later, lightning strikes the barn and starts a fire. Yonie saves all the animals, living up to the responsibility given by his father.
