Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman who is best known for his work in the field of electricity. He developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and the long-lasting, practical electric light bulb. Dubbed "The Wizard of Menlo Park", he was one of the first inventors to apply the principles of mass production and large-scale teamwork to the process of invention, and because of that, he is often credited with the creation of the first industrial research laboratory. He is credited with the development of many important devices and technologies, including the light bulb, the phonograph, and the motion picture camera. Edison was a highly successful and influential inventor, with more than 1,000 patents to his name. He was also a pioneering entrepreneur, founding companies such as General Electric and the Edison Electric Light Company. "Many of life's failures are people who did not realize how close they were to success when they gave up."

The Metropolitan Opera was founded in 1883, with its first opera house built on Broadway and 39th Street by a group of wealthy businessmen who wanted their own theater. In the company’s early years, the management changed course several times, first performing everything in Italian (even Carmen and Lohengrin), then everything in German (even Aida and Faust), before finally settling into a policy of performing most works in their original language, with some notable exceptions. The Metropolitan Opera has always engaged many of the world’s most important artists: Christine Nilsson, Marcella Sembrich, Lilli Lehmann, Nellie Melba, Emma Calvé, De Reszke brothers, Jean and Edouard, Emma Eames, Lillian Nordica, Enrico Caruso, Geraldine Farrar, Rosa Ponselle, Lawrence Tibbett and more. Some of the great conductors have helped shape the Met: Anton Seidl, Arturo Toscanini, Gustav Mahler, Artur Bodanzky, Bruno Walter, George Szell, Fritz Reiner, and Dimitri Mitropoulos.
