One significant aspect of Black history in the field of medicine is the story of medical patents held by Black inventors. One notable example is the invention of the improved Traffic Signal by Garrett Morgan. In 1923, Morgan patented his invention of a three-position traffic signal, which included a warning position to alert drivers before the signal changed to stop or go. This innovation helped improve road safety and traffic flow, benefiting people of all races.

Another example is the invention of the disposable syringe by Phil Brooks in the 1970s. Brooks, an African American nurse, recognized the need for a more hygienic and efficient syringe design. His invention was patented and has since become a standard tool in healthcare settings worldwide.

These examples demonstrate the contributions of Black inventors to the field of medicine through their patented innovations, which have had a lasting impact on healthcare and public safety.
