Today's Black American (Freedmen) inventor or innovator is Dr. David Blackwell. Dr. Blackwell is considered one of the most important mathematicians and statisticians of the 20th century. He made major contributions to dynamic programming and developed the Blackwell Approachability Theorem, both of which underpin modern machine learning and artificial intelligence, particularly in areas like reinforcement learning and decision-making. #BlackHistoryMonth

Today's Black American (Freedmen) innovator is Dr. Ernest Everett Just. Often called a "scientist's scientist," Dr. Just proved the cell's surface was a dynamic, vital structure at a time when most in the world believed only the nucleus mattered. By showing how the cell's outer layer regulates development, he laid the conceptual groundwork for epigenetics. He also pioneered the principle of "normality," insisting that cells be studied in their natural environments to ensure experimental accuracy. This holistic approach remains a cornerstone of modern biology and embryology. #BlackHistoryMonth

Today's Black American (Freedmen) inventor is Patricia Cowings. In the 1970s, Cowings became the first American woman to be trained as a scientist astronaut. However, what she is most known for is developing the autogenic-feedback training exercise (AFTE), a treatment for space motion sickness she developed and patented. AFTE teaches people to control up to 20 physiological responses--such as heart rate, skin conductance, muscle reactivity and blood pressure--to overcome motion sickness and improve performance during high-stress tasks. This is still used by NASA to this day. #BlackHistoryMonth
