The heydays of the company boasting many innovations and inventions begin after Edmund Johann Krüss’ son, Hugo, took over the management. Dr. Hugo Krüss’ handbook of electrotechnical photometry lays the groundwork for this subject



The son of Dr. Hugo Krüss, Paul, takes over the company and leads it successfully through World War II and the time of reconstruction. He not only makes important contributions to the spectral analysis and photometry, but he also invents and produces the corresponding devices, among other things, for school lessons
