Gisela Eckhardt

Gisela Eckhardt (28 October 1926 – 30 January 2020)^[1] was a German physicist and co-developer of the Raman laser.

Early years

Eckhardt grew up as a child of a Frankfurt electrical wholesaler, who died when she was only 13 years old. She became interested in physics at the age of 12 while at the Wöhler School in Frankfurt.^[2]

After graduation she studied physics at the

She then went to the United States together with her husband Wilfried, who also received his PhD in physics shortly before. There, they first worked for the electronics group RCA, where they had to go to another laboratory of the group, since married couples were not hired there at the time. While her husband was in Princeton's main lab, she was in the semiconductor lab in Somerville, at a slightly lower pay. She managed to invent an improved method for polishing silicon wafers, but this did not promote her career. She was openly told that she needed to work twice as hard as a man to be promoted.[2]

In 1960, like many other RCA employees who were dissatisfied with management and pay, she moved to California's booming high technology industry, and in 1960, with her husband, accepted a much larger job offer from

Soon after patenting, for personal reasons, she moved to a department that developed methods for converting AC to DC and vice versa in power electronics, and later became her husband's laboratory manager. Together with her husband, she successfully ran various photo shops in the US as a franchisee.

From 1977 to 1979, she was on the executive committee of the Gaseous Electronics Conference, where she organized panel discussions. In 1982 she co-edited Applied Physics A (Solids and Surfaces). In 2014 she gave a keynote address at the Europhoton Conference in Zürich on the occasion of the 50th anniversary of her discovery.^[2]

Eckhardt lived in Malibu and in Frankfurt-Sachsenhausen.
