Abstract
Dr. phil. habil. Walter Heinrich Geffcken was the first senior researcher to get involved in full time optical coating research at the Jenaer Glaswerk Schott & Gen. Due to circumstances beyond his control he was forced to work in secrecy and without scientific peer exchange. Several of his results were rediscovered many years later. When asked in 1992 to contribute to this book an article on his early work in optical coatings, he gladly accepted. He wrote several letters presenting his views and suggesting topics. He asked for copies of his meticulous internal reports which had survived the dramatic transfer from Jena to the new location in Mainz. But fate did not allow him to finish this task. Walter H. Geffcken died, 91 years old, on April 4, 1995. Now it is up to us to finish the task.
