About Jena

Jena is a city in Germany with a population of around 110.000 people. Together with Erfurt and Weimar it forms the central metropolitan area of Thuringia with approximately 500.000 inhabitants.

Jena’s unique significance lies in its dual legacy:

  • Philosophically and aesthetically, it was the cradle of German Idealism and Romanticism, shaping modern ideas of self, freedom, and art.
  • Scientifically, it became a world leader in optics, thanks to the synergy of Zeiss, Abbe, and Schott.

Jena in Philosophy and Aesthetics

Jena was a hub of German Idealism and Romanticism around 1785–1806, a golden era for aesthetics and philosophy:

Johann Gottlieb Fichte, Friedrich Wilhelm Joseph Schelling, and later Georg Wilhelm Friedrich Hegel all taught or studied in Jena, making it a center of German Idealist philosophy.

The Jena Romantics, including Novalis, the Schlegel brothers, and Caroline Schlegel-Schelling, lived and worked there, blending philosophy, poetry, and early psychology.

The aesthetic theories emerging from Jena emphasized the unity of art and nature, subjective experience, and art as a form of knowledge.

Jena in Optics and Science

Jena gained international importance in optics, thanks to a collaboration between science, craftsmanship, and industrial vision:

Carl Zeiss (1816–1888) founded a precision optics workshop in Jena in 1846. He focused on making high-quality microscopes.

Ernst Abbe, a physicist and mathematician, joined Zeiss in the 1860s and revolutionized optical theory, establishing the Abbe sine condition and improving lens design with scientific rigor.

Otto Schott, a chemist, developed new types of optical glass that allowed more precise instruments. He co-founded Schott AG.

This led to Jena becoming a global leader in optical instruments, giving rise to Carl Zeiss AG, a company still famous today in the fields of microscopy, camera lenses, and medical devices.

Jena Today

Jena remains a center for philosophy, cultural studies, and optical sciences through its Friedrich Schiller University and high-tech research institutions.

The interplay of science and the humanities is still a key theme in Jena’s academic identity.
