When the first edition of this work was published (1912) there were few treatises that examined the physiology and technical aspects of lighting that was being deployed throughout manufacturing enterprises, and was being taught to new engineers. The author credits General Electric Company of Schenectady with the rapid progress in this field during the previous ten years which necessitated a significant rewrite of the first edition.
The author Bohle was Professor of Electrotechnics at the University of Cape Town, a Fellow of the Royal Society of South Africa, and a Member of the Institution of Electrical Engineers.
