The history of television records the work of numerous engineers and inventors in several countries over many decades. The fundamental principles of television were initially developed using electromechanical methods to scan, transmit and reproduce an image. As electronic camera and display tubes were perfected, electromechanical television gave way to all-electronic broadcast television systems in nearly all applications.

The beginnings of mechanical television can be traced back to the discovery of the photoconductivity of the element selenium by Willoughby Smith in 1873, the invention of a scanning disk by Paul Gottlieb Nipkow in 1884 and John Logie Baird's demonstration of televised moving images in 1926.

As a 23-year-old German university student, Paul Nipkow proposed and patented the first electromechanical television system in 1884. Although he never built a working model of the system, variations of Nipkow's spinning-disk "image rasterizer" for television became exceedingly common, and remained in use until 1939.Constantin Perskyi had coined the word television in a paper read to the International Electricity Congress at the International World Fair in Paris on August 25, 1900. Perskyi's paper reviewed the existing electromechanical technologies, mentioning the work of Nipkow and others.

Jeffrey Warren "Jeff" Daniels (born February 19, 1955) is an American actor, musician and playwright. He founded a non-profit theatre company, the Purple Rose Theatre Company, in his home state of Michigan. He has performed in a number of stage productions, both on and off Broadway, and has been nominated for the Tony Award as Best Actor for the Broadway play God of Carnage (2009), along with his other three cast-mates.

He has had a thriving film career, from his debut in 1981 in Ragtime, through State of Play in 2009. For his film work, he has received three Golden Globe Award nominations, including as Best Performance by an Actor in a Motion Picture—Comedy/Musical for Woody Allen's The Purple Rose of Cairo (1985) (hence the name of his theatre company). He has also received nominations by the Screen Actors Guild, Satellite Awards, and several others for his work in The Squid and the Whale (London Critics Circle Awards, Independent Spirit Awards, Chlotrudis Awards and Gotham Awards). He played Debra Winger's husband in the 1983 Oscar-winning film Terms of Endearment.
