Be sure to catch Ernest Freeberg, head of the history department, at 9:00 p.m. Tuesday, January 27, on PBS’s American Experience. Freeberg was interviewed about Thomas Edison. In the show he profiles the inventor whose achievements include a long-lasting incandescent light bulb. A review of the two-hour program can be found in the New York Times. Freeberg is the author of The Age of Edison: Electric Light and the Invention of Modern America. In his book, Freeberg weaves a narrative that reaches from Coney Island and Broadway to the tiniest towns of rural America, tracing the progress of electric light through the reactions of everyone who saw it. It is a quintessentially American story of ingenuity, ambition, and possibility, in which the greater forces of progress and change are made visible by one of our most humble and ubiquitous objects.
