It’s impossible to determine how many people would have lost their lives without the contribution of African-American inventor Dr Charles Drew.
Charles Drew was born on June 3, 1904, in Washington, DC. His early interest was in education, but he was also an outstanding athlete. While in college, he was awarded as the man who contributed the most to sports during his four years in school. Drew’s sister Elsie suffered from tuberculosis(肺结核) and died in 1920. Her death influenced his decision to study medicine.
