A dwarf with the circus, Curpo works with the elephants in Germany, helping Josef and Bram care for them. Curpo helps Bram make his escape to America to care for Modoc, and returns later in Bram's life when he eventually winds up working with Modoc in Mr. North's circus. Curpo also works in the circus, once again assisting Bram with the care of Modoc.
Curpo dies after a circus fire in the big tent, trying to save as many others as possible. Bram never gets over the loss of one of his oldest friends.
