1. A new system of alternate current motors and transformers
Lecture given at the American Institute of Electrical Engineers in New York, May 16, 1888.
2. Experiments with alternate currents of very high frequency and their application to methods of artificial illumination
Lecture given at the American Institute of Electrical Engineers at Columbia College, New York, May 20, 1891.
3. Experiments with alternate currents of high potential and high frequency
Lecture given to the Institute of Electrical Engineers in London on February 3, 1892, and at the Royal Institute in London on February 4, 1892. It was given again to the International Association of Electrical Engineers and to the Société Française de Physique in Paris.
4. On light and other high frequency phenomena
Lecture given at the Franklin Institute in Philadelphia on February 24, 1893, and at the National Electric Light Association in St Louis on March 1, 1893.
5. On mechanical and electrical oscillators
Lecture given on August 25, 1893, in the hall adjoining the Agricultural Building at the Chicago World’s Fair. This lecture was not published and the manuscript was not preserved among Tesla’s papers. It was most probably destroyed, along with his other belongings, in the fire of March 13, 1895. Thanks to journalist and publicist T.K. Martin, a detailed overview of the lecture and Tesla’s experiments appeared in the press at the time.
6. High frequency oscillators for electrotherapeutic and other purposes
Lecture given to the Electro-Therapeutic Society in Buffalo on September 13, 1898.
7. High-frequency oscillators and controls for electric circuits
Lecture given to the New York Academy of Sciences on April 6, 1897.
8. On the art of teleautomatics
Lecture given on May 13, 1899, at the Chicago Business Club. This lecture is preserved in an incomplete and unfinished form in the Archives of the Nikola Tesla Museum.
9. The phenomenon of high frequencies
Experimental demonstrations in the Havemeyer Hall of Columbia University, New York on the evening of April 12, 1901.
10. New inventions by Tesla
Lecture at a meeting of the New York branch of the National Electric Light Association held in the New York building of the Association of Electrical Engineers on the evening of Monday, May 15, 1911.
