Thanks to Boykin’s work, we can now set an exact resistance value for the wiring in our electronics. This has allowed our televisions, PCs, and radios to make leaps and bounds to the modern devices we have today. Boykin’s work also led to the implantable pacemaker – a medical device used by millions to treat heart disease.

Mark Dean: Assistance in creating the first gigahertz chip, a color PC monitor and more


Mark Dean – computer scientist, engineer and IBM Fellow – worked with IBM to develop technologies like the first gigahertz chip. Dean has since received numerous awards and received his PhD from Stanford. His work was monumental and affects our daily lives in many ways, paving the way for today’s computers and game consoles.

Think about Jesse Russell every time you pick up your smartphone. During his decades in the telecommunications industry, Russell was instrumental in bringing cellular communications up to date. Numerous patents in the field for innovations such as its wireless communication base station and mobile data phone.

Fredrick McKinley Jones: Automatic Cooling System for Long Distance Trucks


Another inventor we have to thank for our modern conveniences is Fredrick McKinley Jones. He made it possible to ship items that need to stay cool with numerous patents for cooling. He also contributed to other industries, particularly film, as well as the medical field. Only when you buy products in store or order perishable goods online has Jones’ work helped make it happen.

Jerry Lawson: Fairchild Channel F video game console and cassette


Lawson helped develop the Fairchild Channel F console, the first cartridge gaming system, in 1976. With games like video blackjack, bowling, checkers, and slot machines, it was none other than the games we have today. But without Lawson’s work, we might not have today’s highly graphic titles or consoles. Some people even refer to Lawson as the father of modern gaming.

Alice H. Parker: Gas stove


Alice Parker patented a natural gas stove in 1919. Their invention helped modernize the HVAC industry and central heating systems, enabled better energy savings, and removed us from reliance on wood and coal. Needless to say, our houses are now much more comfortable thanks to their revolutionary concept.

Garrett Morgan: Three position traffic light


Getting stuck at a signal in traffic is the worst, but these signals play an important role in regulating traffic. Morgan generated a T-shaped automated signal with three positions including a warning position. He sold the invention for $ 40,000.

Roy Clay: computer science pioneer


In the 1960s, Roy Clay led the team at HP that came out with the 2116A. He also developed software for the computer. A hugely influential figure in modern technology, Clay has worked on developing electrical safety testers and has helped others get involved in the technology industry.

Marie Van Brittan Brown, who created the first home security system, applied for a patent in 1966 for her invention of the CCTV (Closed Circuit Television Security) system. CCTV systems are used to this day, and thanks to Brown’s contribution, homes and businesses are deployed in every area of ​​the world has affordable access to home security.

Shirley Jackson: Charge Density Wave Research


Shirley Jackson remains one of the most impressive people of all time. In addition to her doctorate in particle physics, Dr. Jackson worked with Bell Laboratories on research related to charge density waves. Charge density waves are important for the creation of high temperature superconductors that have all possible technological applications. President Bill Clinton even named Jackson chairman of the US Nuclear Regulatory Commission.

Lisa Gelobter: Contributing to Shockwave, Hulu, and more



Not only was Obama Chief Digital Service Officer of the Department of Education promised, but he was also involved in many of the technologies we use today. She worked on Hulu and Shockwave, and is even held responsible for creating the animation used in GIFs. And as if that weren’t impressive enough, Gelobter acted as chief digital officer for BET Networks.

James E. West: electret microphone


Foil electret microphones may not sound as exciting, but the technology is used in nearly 90% of all microphones produced annually. West patented the electret microphone in 1962 and now it can be found in everything from telephones to hearing aids to baby monitors, not to mention a host of other devices.

Lewis Latimer: carbon filament for lightbulbs

Lewis Latimer worked on some fairly landmark inventions, but often receives little recognition. He worked with Alexander Bell to design his patent for the telephone, for example, and he patented the carbon filament for the light bulb. Latimer’s contributions have fundamentally changed the way we live, work and communicate.

Gladys West: Contributions to GPS


GPS is almost ubiquitous these days and is used in everything from travel to weather to the military. However, the technology would not be possible without the contributions of Gladys West. As a mathematician and programmer, West programmed a computer to perform calculations for a geodetic earth model that enabled GPS.

Granville Woods: Induction Telegraph


Granville Woods invented a few devices, including a hybrid telephone-telegraph that allowed people to talk over telegraph wires. Additionally, Woods created the troller, which enabled trolleys to receive power from overhead lines. His contributions played an important role in our communications, electronics, and travel industries.

Marc Hannah: 3D graphics software


Marc Hannah is a world-renowned inventor, chief architect, and co-founder of Silicon Graphics, Inc. (SGI). As the architect of the 3D effects software, he contributed directly and indirectly to various fields including the film industry and the military. If you’ve ever thought the special effects at Jurassic Park were impressive, then thanks to Hannah.

Frank S. Greene: High Speed ​​Semiconductor Computer Storage Systems


Frank S. Greene, electrical engineer, inventor, teacher, and attorney, was a Silicon Valley powerhouse. As a PhD student and one of the world’s leading providers of semiconductor technology, Greene has applied for a patent for an integrated circuit. His patent helped Fairchild become a leader in semiconductor technology in the 1960s.
