In 1896 the Electrical Review published some articles on x rays developed by Tesla. It appeared at the same time as when Roentgen announced his discovery of X-rays but he never attempted to proclaim priority and they shown their respect to eachother. Tesla experimented with shadowgraphs similar to those that later were to be used by Wilhelm Rontgen when he discovered X-rays in 1895. He also developed experiments including a carbon button lamp and other types of lighting, which could shine by the power of electrical resonance. One invention consisted in a special vacuum tube which emitted light to be used in photography.
