My father was teacher and principal at a segregated school in Evansville, Indiana.
I was the first African American (in the world!) to receive a Ph.D. in mathematics.
In 1925 when I received my Ph.D. from Cornell University, only 28 Ph.D.'s in mathematics were awarded in the United States, but 31 black men were lynched that same year.
After a brief four year stint at West Virginia State College, I joined the Howard University mathematics faculty and taught there the remainder of my life.
Regarded as a popular and respected teacher, I published only two research papers...such was not important relative to the other issues I had to face.
