Dr. Classen

The family doctor

Herr Sesemann's friend and doctor. He sees that Heidi is sick from homesickness, and he finds peace on the mountain himself.

Dr. Classen is the Sesemann family doctor and Herr Sesemann's trusted friend. He is kind and observant, and he understands Heidi at once. When he finds her sleepwalking, he does not scold her but gently asks what she was dreaming.

He is also grieving the loss of his own daughter, which makes him more sensitive to the pain of others. He is a thoughtful, honest man who speaks plainly and acts on what he sees.

“Sesemann, the child is wasting away from severe homesickness. Medicine cannot heal her.”
