Another extraordinary woman is German glassmaker Marga Faulstich, who was a pioneer researcher for the ZEISS sister company SCHOTT for over four decades. From 1939, she was part of a research group submitting a patent that has served as a basis for the manufacturing of sunglasses, anti-reflective glasses and glass facades ever since. In the course of her career, another 40 patents followed, many of them still used in glass manufacturing worldwide. After World War II, Faulstich was among a group of 41 specialists and executives who were brought to West Germany because of their knowledge and skills in the glass industry. From 1952, Faulstich became the first female manager at the new SCHOTT factory in Mainz. She continued to research and develop new glasses, particularly special glasses for microscopes and telescopes. In total, over 300 types of optical glasses can be traced back to the inventiveness of this remarkable researcher. Marga Faulstich died in 1998 at the age of 82.
