Heinrich Gravenhorst

Christoph Johann Heinrich Gravenhorst (26 September 1823 – 21 August 1898) was a German schoolteacher and beekeeper who wrote an influential textbook on apiculture called the Der Praktische Imker (1873) which went into several editions.

He invented a straw beehive with movable frames which is called Gravenhorst's Bogenstülper.

From his parents who kept a farm with an apiary, he learned traditional beekeeping methods at a very early age.

He studied the works of pastor Dzierzon and August von Berlepsch but also began to examine traditional bee-keeping in the old Lüneburg region.

He lost the case despite being supported by German beekeepers and was forced to sell off his home and leave Braunschweig in 1887 to settle in Wilsnack.
