Johann Philipp Eduard Gaertner was a German painter of the second quarter of the 19th century, the Biedermeier era. He is known as a landscape painter, famous for his views of Berlin and other cities.
Eduard Gaertner created many architectural landscapes of Berlin, as well as St. Petersburg and Moscow during his travels to Russia. The value of these works is that they documented the appearance of the cities on the eve of the age of photography. Gaertner's painting style underwent a change after the death of King Friedrich Wilhelm III, his patron. In keeping with the cultural attitudes of Prussia's new ruler, the artist began to paint more romantic and idealized landscapes in which architecture played a decorative role.
Otto Guericke, from 1666 von Guericke (pronunciation and original spelling: Gericke) was a German politician, jurist, physicist and inventor. He is best known for his experiments on air pressure with the Magdeburg hemispheres. He is considered the founder of vacuum technology.
