Happy 90th birthday!
Professor Christian Bartenbach celebrates his 90th birthday today!
Most of the 90 years of his life were "light years"! Anyone who has dealt with daylight or artificial light more intensively could not get past it! He has been called "Pope of Light, Light Pioneer, Master of Light" through his successful realization of many well-known national and international projects.
The whole Bartenbach team congratulates him!
