Werner H. Bloss (1930 – 6 June 1995) was a scientist known for his work in the field of photovoltaics.
In 1955 he took the position of a research assistant at the Institute of Gas Discharge Techniques and Photoelectronics at the University of Stuttgart.
In his doctoral thesis he described the noble gas filled thermionic converter developed by him.
In the early sixties, very successful research work on various types of thermionic converters was performed under his guidance at the above-mentioned institute.
During his two-year stay in the United States his field of interest widened again to take in optical methods of image processing.
