What modern inventions came from black people?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
Black inventors and scientists have created a wide range of modern technologies—from consumer toys and household tools to life‑saving medical processes and core electrical and computing advances—and their contributions are documented across encyclopedias, institutional histories and feature reporting [1] [2] [3]. Historical undercounting and myths about who “invented” familiar items mean the record needs careful correction: some commonly repeated claims (for example, that George Washington Carver invented peanut butter) are myths, while many genuine breakthroughs remain underrecognized [4] [5].
1. Everyday objects and safety devices that entered mass life
Several Black inventors are directly responsible for objects that entered everyday life and public safety: Garrett Morgan patented an improved traffic signal (adding the caution/“yellow” phase) and a breathing hood that influenced later gas‑mask designs [2] [6], and Sarah Boone improved the ironing board in the 19th century [7]. These inventions illustrate how Black innovators often solved routine but dangerous practical problems, creating technologies that scaled rapidly into public use [7] [8].
2. Breakthroughs in electrical, telecommunication and computing infrastructure
Contributions to foundational electrical and computing technologies include Lewis Latimer’s carbon‑filament work that helped lengthen practical electric‑light bulbs and his patent drafting for early telephony [7] [5], and Mark Dean’s engineering at IBM that helped produce the color PC monitor and advance microprocessor performance (including work toward the first gigahertz chip) [8]. These inventions are part of the hardware backbone that made modern electrified and digital life possible [5] [8].
3. Medical and biochemical advances that lowered cost and saved lives
Black scientists have driven major medical advances: Percy Lavon Julian developed scalable syntheses for steroids and cortisone‑related compounds, lowering costs for important drugs [3], and Charles Richard Drew established practices for blood banking used in modern transfusion systems [6] [9]. These are not marginal inventions but structural contributions to 20th‑century medicine and public health [3] [9].
4. Transportation, refrigeration and industrial innovations
Practical industrial inventions include Frederick McKinley Jones’s refrigerated truck and railcar systems that revolutionized food distribution and cold‑chain logistics [3], and Elijah McCoy’s lubrication devices (noted in broader histories) that improved machine reliability and industrial efficiency [5]. Such inventions transformed supply chains and manufacturing—a quieter but fundamental set of modernizations [5] [3].
5. Consumer culture and technologies often misattributed or mythologized
Popular narratives sometimes misattribute or mythologize; for example, George Washington Carver did not invent peanut butter but developed hundreds of agricultural uses for peanuts and sweet potatoes that aided farmers [4] [1]. Conversely, widely used consumer products like the Super Soaker water gun were created by Lonnie Johnson, an engineer‑inventor whose toy became America’s top seller in the early 1990s [1]. Correcting myths and celebrating accurate attribution are both necessary to understand the true scope of Black invention [4] [1].
6. Why many contributions remain hidden and how scholarship is changing the picture
Scholars and institutional projects argue that Black inventors were systematically undercounted—Henry Baker’s early 20th‑century patent survey and recent database work show more inventions than traditional histories record—and historical racism constrained opportunities for patenting, commercialization and credit [5] [10]. Museums, the Library of Congress and research centers have begun compiling large lists and exhibits to recover these histories, but gaps remain and claims outside these documented sources cannot be confirmed here [11] [10].
