Abstract :
In June 1926 C. P. Jensen, Managing Director of the Osram Company, Berlin, lectured at Wiesbaden before the 31st Congress of the Association of German Engineers. Mr. Jensen stated that the “aim of illuminating economics is to treat light economically like any other raw material and to see to it that the expenses for light are compared with the useful effect obtained and examined as to their justifiability in order to avoid wasteful and extravagant management either from a misinterpreted sense of economy and thrift or prodigality.”
