Florence Barbara Seibert was born in Pennsylvania in 1897. When she was three, Florence got sick from a disease called polio. Although she recovered, she walked with a limp for the rest of her life. Even at a young age, Florence loved to read about famous scientists and realized she wanted to help people who suffered. In the 1920s, she was studying science at Yale University when she made an important discovery. She uncovered dangerous bacteria in the solutions used to make vaccines and other kinds of shots. Florence figured out a new way to get rid of all the bacteria and made injections much safer.

During his studies, Drew became fascinated by blood transfusions—the process when someone receives blood during a surgery or illness. Charles discovered that blood could be stored longer if the liquid part of the blood, or plasma, was separated, something we do today in blood banks.
These “banks” allow people to donate blood to the sick or injured, saving lives. Because of his research, Charles became the first African American to receive a Doctor of Medical Science degree from Columbia University.
During World War II, Charles led a program to send blood plasma to injured soldiers. At that time, many laws separated White and Black Americans. The U.S. military kept White and Black Americans’ blood separate. Charles argued that there was no scientific reason to do that, but the military insisted on it. Charles protested and left the program to train new doctors instead.
In 1944, Charles received the highest honor from the National Association for the Advancement of Colored People. His legacy lives on in the lifesaving blood donations happening every day.
