Lectures On Illuminating Engineering is a republication of a series of lectures delivered at Johns Hopkins University in October and November 1910. This volume focuses on the fundamental principles and practical applications of illuminating engineering, offering insights into the science and art of lighting.

Presented in collaboration with the Illuminating Engineering Society, the lectures cover a range of topics, including light sources, photometry, and the design of lighting systems. Though published in 1911, the content offers a valuable historical perspective on the evolution of lighting technology and engineering practices. This volume serves as a foundational resource for anyone interested in the history and development of illuminating engineering.
