In 1923, Morgan patented a device known as the “Morgan Traffic Signal,” which became a significant milestone in improving road safety and regulating vehicular traffic.

Morgan’s traffic signal was designed to address the growing challenges posed by increased automobile traffic in urban areas. His device featured a three-position signal, with red, yellow, and green lights, which controlled the flow of vehicles at intersections.

This innovation helped to reduce traffic accidents and streamline the movement of vehicles, creating a safer and more organized transportation environment. The adoption of Morgan’s traffic signal was a pivotal moment in urban planning and traffic management. It served as a model for subsequent iterations of traffic control systems, influencing the development of standardized traffic signals used worldwide today.

Garrett Morgan’s invention has had a lasting impact on public safety and remains an essential element in ensuring efficient and orderly traffic flow in cities globally.

4. Refrigerator 

Frederick McKinley Jones, an African American inventor and entrepreneur, revolutionized the field of refrigeration with his groundbreaking invention of the automatic refrigeration system for long-haul trucks. Born in 1893 in Cincinnati, Ohio, Jones showed an early aptitude for mechanics and engineering.

In 1935, he received a patent for his creation, which ultimately transformed the transportation and storage of perishable goods. Jones’ invention paved the way for the modern refrigerated truck, allowing fresh produce, dairy, and other perishable items to be transported over long distances without spoiling.

This development had a profound impact on the food industry, reducing waste and ensuring a more reliable supply of fresh goods to consumers across the nation. The refrigeration system not only improved food safety but also played a crucial role in the growth of the frozen food industry.

Frederick McKinley Jones went on to co-found Thermo King Corporation, a company that became a leading manufacturer of transport refrigeration units. His contributions to the refrigeration industry earned him numerous accolades, including the National Medal of Technology posthumously in 1991.

5. World’s First Human-Programmable Computer Language 

Rear Admiral Grace Hopper, a pioneering African American computer scientist and naval officer, played a pivotal role in the development of the world’s first human-programmable computer language. Born in 1906, Hopper’s illustrious career began during World War II when she worked on the Harvard Mark I computer.

In the 1950s, she led the team that developed the UNIVAC I, the first commercially produced computer in the United States. Hopper’s most significant contribution came with the creation of COBOL (Common Business-Oriented Language) in the early 1960s.

COBOL was a breakthrough in programming languages, designed for business and data processing. Its user-friendly syntax allowed for easier coding and debugging, making it accessible to a broader range of users. COBOL quickly became the foundation for countless business and administrative applications, establishing Hopper as a trailblazer in the world of computing.

Rear Admiral Grace Hopper’s legacy extends beyond COBOL, as she continued to make substantial contributions to the field of computer science throughout her career. Her pioneering work laid the groundwork for the development of modern programming languages.

6. Portable Electric Hair Straightener 

Madame C.J. Walker, born Sarah Breedlove in 1867, was not only an entrepreneur and philanthropist but also a trailblazer in the beauty industry. Recognized as the first female self-made millionaire in the United States, Walker’s innovations included the creation of a portable electric hair straightener.

During the early 20th century, Madame C.J. Walker developed and patented a revolutionary hair straightening comb specifically designed for use with electricity. This portable device marked a significant advancement in hair care for African American women, providing them with a convenient and efficient means of straightening their hair.
