The Herzberger Quader is a solid dissection puzzle invented by German mathematics teacher Gerhard Schulze.
[1] It was named after his home-town Herzberg, and Quader is the latin-derived German word for a rectangular cuboid.
The Herzberger Quader consists of a set of all possible polycubes from dicube to tetracubes.
[2] Besides stowing the Herzberger Quader in its box there are a lot of figures that can be built using all parts.
[2] Author of the Herzberger Quader is Oberstudienrat Gerhard Schulze (1919–1995), who was intensively engaged in mathematical games during his extracurricular activities in the years 1982–1994.
