Dr Hans Gerhard Lubszynski
c.1910 Born in Germany
1931 Gained a doctorate in Berlin, working under Professor Max Knoll.
From 1931 to 1933 he worked for Siemens and Halske, on amplifier valves
Tedham's team was split into two, with James McGee leading the group working on camera tubes and L. Broadway working on receiver tubes. Lubszynski joined McGee's team, and worked closely with him on various camera tube development and improvements. He also worked on image convertors, image intensifiers and thin film transistors.
1942 he was elected a Fellow of the Institute of Physics.
1951 Lubszynski led the development of the Vidicon, a television camera tube based on photoconduction rather than photoemission. In the vidicon the light image was focussed on a target layer, where it was converted into an electrical charge image which was then explored by a scanning electron beam. Lubszynski developed the vidicon for various applications including microscopy, where it could give direct television display of what was being examined.
From 1962 he worked on the Plumbicon, a vidicon with a lead oxide target.
During his time at EMI he took out over 100 patents mainly on camera tubes.
He also published several papers, including two for the IEE that won premiums, in 1939 and 1955.
1968 retired from EMI.
