The benefits of the light bulb are so interwoven throughout our lives, few would argue we take them for granted – until we notice their infamous ultra-luminescence just moments prior to our world becoming dark. However, back in 1879, Edison had received enough grief concerning his invention he would often feel compelled to provide a defense – some of which appeared in newspapers throughout the country. Such was the case with the December 27, 1879 issue of The Sun  (New York). I appreciate the irony of a discussion regarding artificial light appearing in an issue of The Sun. Enjoy.
