Lovely addition to a windy post. But in the late part of the 19th century, Zeiss in Dresden & Jena assembled a team to include: Dr. Ernst Abbe(

And just to consider the technology developed in the city of Jena and country of Germany, Jorg Schilling, after studying under Dr. Oscar Gaddy at the University of Illiniois, re-discovered the art of case color hardening at the Friedrich Schiller University in Jena.
