The life-long inventor, Lee de Forest invented the three-element vacuum tube used between 1906 and 1916 as a detector, amplifier, and oscillator of radio waves. Beginning in 1918 he began to develop a light valve, a device for writing and reading sound using light patterns. While he received many patents for his process, he was initially ignored by the film industry. In order to promote and demonstrate his process he made several hundred sound short films, he rented space for their showing; he sold the tickets and did the publicity to gain audiences for his invention. Lee de Forest officially brought sound to film in 1919. Lee De Forest: King of Radio, Television, and Film is about both invention and early film making; de Forest as the scientist and producer, director, and writer of the content. This book tells the story of de Forest’s contribution in changing the history of film through the incorporation of sound. The text includes primary source historical material, U.S. patents and richly-illustrated photos of Lee de Forest’s experiments. Readers will greatly benefit from an understanding of the transition from silent to audio motion pictures, the impact this had on the scientific community and the popular culture, as well as the economics of the entertainment industry.

Series fiction about wireless and radio was a popular genre of young adult literature at the turn of the 20th century and an early form of social media. Before television and the Internet, books about plucky youths braving danger and adventure with the help of wireless communication brought young people together. They gathered in basements to build crystal sets. They built transmitters and talked to each other across neighborhoods, cities and states. By 1920, there was music on the air and boys and girls tuned in on homemade radios, often inspired by their favorite stories. This book analyzes more than 50 volumes of wireless and radio themed fiction, offering a unique perspective on the world presented to young readers of the day. The values, attitudes, culture and technology of a century ago are discussed, many of them still debated today, including immigration, gun violence and guns on campus, race, bullying and economic inequality.

Two professors and a preacher invented Columbus radio. It began with science experiments in classrooms and a minister s desire to expand beyond his churchgoing audience. By 1922, government licenses had been issued for WEAO at Ohio State University and WJD at Denison University. At this same time, a Baptist minister went on the air for an hour each Sunday morning using a 10-watt transmitter licensed as WMAN. In this story of Columbus radio, the work of the professors and the preacher will evolve into radio with advertiser-supported programs of information and entertainment. Three important radio stations will serve a growing Columbus radio audience in different ways: WEAO becomes WOSU, a national pioneer in using radio for teaching; WMAN becomes WCOL and in the 1960s is number one in audience size; and CBS affiliate WBNS becomes the class act of Columbus radio, retaining the major share of local listeners for many decades. Including many other stations of lesser influence, the illustrated stories of Columbus radio are told in this book."
