Dear readers,
fellow Planetarians,

Here you will find impressions and information about my different planetarium projects
from the last decades.

The years 2024 and 2025 mark the centenary of the invention of the projection planetarium.
For this occasion, I have developed a 35-minute planetarium program called “One Hundred Years of Eternity.”
An excerpt can be found further down on this page. Based on this show I'm currently working on an
approximately 55-minute planetarium program entitled “Our Heavenly Story”.

Under the menu item "Portfolio" you can find information about past planetarium programs such as
“The Silver Sail” or “Cirque de la Sphere” and initiatives such as the “DIVE – Festival for Immersive Arts”.
If you are interested in one of the projects or have any questions, please get in touch.

100 years of eternity

Hardly anything has shaped the history of civilization as much as man's confrontation with the heavens.
Megalithic stone circles bear witness to this, as do the astronomical origins of science in ancient Greece
or the technical principles of modern high seas navigation. Even prehistoric sites tell of the important role
the heavens have always played for people, whether in their practical everyday lives or as a repository for
mythological imaginings spanning the generations.

The planetarium is the latest representation in a long series of sites and inventions reaching far back
into human history that served our preoccupation with the starry heavens and the cosmos
surrounding us. On the occasion of the centennial of the invention of the projection planetarium,
we embark on a journey which begins with the early cultures of mankind and leads along an
ever-changing view of the heavens to the modern star theater.
