Luke Tooker as Johann Seifert

HSU student Mark Teeter plays Humboldt as the young explorer, while HSU Geography professor Stephen Cunha portrays Humboldt (who described himself as a physical geographer) in his later years.

 Luke Tooker plays Johann Seifert, Humboldt’s last companion who serves as the audience’s guide in this play. The rest of the cast performs multiple roles—not all of them human. The characters include mosquitoes, frogs, meteors and a parrot that is the last speaker of a tribal language.
