Gustav Höcker (28 September 1832 - 11 October 1911) was a German author and translator of popular historical novels.
He spent his childhood in Eilenburg, an early industrial center, and received his secondary education in Chemnitz.
Until the age of 26 he was, against his will, a merchant (in 1862 he published Kaufmännische Carrieren: Wahrheit und Dichtung aus dem Geschäftsleben, inspired by his career in trade), an occupation he left to become a professional writer.
He published studies and biographies of drama authors and politicians, and of musicians such as Ludwig van Beethoven, Joseph Haydn, and Wolfgang Amadeus Mozart.
He attained a measure of commercial success with adaptations of novels in English, including novels by James Fenimore Cooper (The Deerslayer and two collections of adapted "Leatherstocking Tales"), Robert Montgomery Bird (Nick of the Woods), and Daniel Defoe (Robinson Crusoe).
