Using radar applications, electromagnetic beams, and a CRT, the gameplay-at least what Goldsmith's patent describes-seem like an ancestor to Space Invaders or Galaxian. Thomas Goldsmith\’s patent US Patent Office
This was likely Goldsmith's motivation when he began work on the what he would later call the " cathode-ray tube amusement device." At war's end, DuMont tried to transform its military innovations into commercials successes. Like many other companies during World War II, DuMont pushed pause on its ordinary business in favor of building wartime technology like radar and missile launching systems. As President Franklin Roosevelt delivered his opening remarks, crowds of people huddled around the sets, all of them probably watching television for the first time. In addition to working on the perfection of the CRT and pioneering color television by experimenting with red, blue, green phosphor, Goldsmith was part of the company delegation that brought DuMont's new fishbowl-shaped televisions to the 1939 World's Fair in Queens, New York.

Goldsmith got much more than a CRT-DuMont hired him as head of research, and Goldsmith joined a team that would change how the world entertained itself, from television sets to TV networks.

Mullards were the leading UK producers of cathode ray tubes during the 1950s, which were in demand by the growing market for television receivers.
CRTs also led to the first early idea for a video game. Several years after that, the nearly simultaneous work of RCA's Vladimir Zworykin (who had worked for Rosing) and Philo Farnsworth led to the using of cathode ray tubes for transmitting recorded images in the first electronic television system. Russian Boris Rosing was the first person to use a CRT in the transmission of black-and-white images, creating what could be considered the first primitive TV. This is one of the reasons why the market moved towards the lightweight LCD and plasma screens in the 2000s. As time went on, televisions grew in size and so did CRTs, leading to the bulky, heavy sets we remember from the 1980s and 90s. When struck by this beam, the phosphor screen produces visible light and creates the traditional tv glow on the glass viewing surface. When electrified, the CRT emits a narrow beam of electrons that pass through electrical coils that deflect, intensify and direct the beam at the phosphor-coated screen (in a black-and-white TV, the phosphor is white). It's made up of three parts: the electron gun, the phosphor-coated screen, and the glass viewing surface. A CRT was essentially the picture tube in a television, the component that creates and receives the beams of electrons that show the image. If you're old enough to remember the days before flat-screen TVs and computer monitors, then you remember how ubiquitous cathode-ray tubes (CRTs) became. Karl Ferdinand Braun, who would later win a Nobel Prize for his work with "wireless telegraphy," created the first cathode-ray tube, naming it the Braun Tube after himself. While the science wasn't fully understood at the time (the scientists thought they were seeing rays or waves, rather than electrons), this discovery became the basis for a slew of electrical innovations. in physics, where he began researching a device that was becoming essential for electronic communications: the cathode-ray tube.Ĭathode rays- beams of high-speed electrons leaving a polarized, heated electric device in a vacuum tube-were first observed in 1869 by German physicist Johann Hittrof and named by Eugen Goldstein. In 1931, he went to Cornell to get his Ph.D. (While she preferred the ear trumpet, the amplifier worked.) Through high school and into undergrad at Furman University, Goldsmith became obsessed with electronics, especially crystal radio sets, a new technology that had just become popular.
Goldsmith, born in 1910, got his start in electronics when he was only ten years old building an amplifier for his hard-of-hearing grandmother who was using an ear trumpet. "It never registered that this would have been the first video game."
