5 facts about Marjorie Lee Browne, African American math prodigy and pioneer

Breaking through barriers of race and gender, she pursued the beauty of pure math

1. For as far back as she can remember, she loved math

Since an early age, Marjorie Lee Browne was a mathematician at heart. She loved it both for the intellectual engagement, as well as the freedom it granted. She once told an interviewer, “I was rather introverted, and as far back as I can remember I liked mathematics because it was a lonely subject. I could do it alone.”

She was born and raised a predominantly black community in Memphis, Tennessee. Browne’s father, Lawrence Johnson Lee, was renowned by friends and family for his mental arithmetic. He had attended college for two years (highly unusual for black men at the beginning of the 20th century) and had enough of a formal education to inspire an early interest in math in both Browne and her brother. Browne's mother died when she was two, and her father whole-heartedly adopted the role of caring for his children – and for the local community at large. He wasn't wealthy, but he did have a steady paycheck, so he'd invite the entire local high school football team over for spaghetti and meatballs before a big game.

Lee sent Browne to the best schools he could: prestigious, predominantly African American private institutions. After graduating with a math degree cum laude from Howard University in 1935, Browne moved to New Orleans to live with her uncle and teach math at a secondary school.

2. She was one of the first African American women to earn a math PhD

In the 1940s, it was extremely unusual for a black woman to earn a bachelor’s degree in math. It was even more unusual for a black woman to take this a step further and pursue graduate work. But Browne loved math, and she wanted more.

So she moved north, where she worked as a teaching assistant while conducting research towards her PhD at University of Michigan. In 1949, she became the third black woman to earn a PhD in math. Her dissertation was titled, "On the One Parameter Subgroups in Certain Topological and Matrix Groups.”

The next African American woman to earn a math PhD didn't do so until 1960. Even today, black women are extremely underrepresented in math, and black men and women only make up about 1 percent of PhDs in math in America.

3. She was a proponent of math education for everyone, especially school teachers

Browne recognized that increasing involvement of black women in STEM fields was a systemic problem, one that needed to be addressed with long term, sustainable solutions. She viewed early education as a primary route to inspire confidence in young mathematicians.

From 1949 to 1979, Browne taught at North Carolina Central University (NCCU), a historically black university. While she served as department chair, NCCU was awarded a prestigious National Science Foundation grant, the first granted to a predominantly black institution, to teach secondary school teachers about advanced mathematics.

Browne spent her summers with local teachers, filling them in on the wonders of linear algebra. She inspired many high school teachers to go on and receive advanced degrees, effectively improving the quality of math education in North Carolina. In the words of one of her former students, “Her thoroughness, demands for excellence and rigor, wisdom, vision, and productive powers in the classroom have profoundly influenced not only the academic growth and development of countless students but also their aspirations to achieve and succeed in the field of mathematics.”

4. Her love for math education triumphed over her own needs

Like many professors, Browne constantly balanced her own research with teaching others. For Browne, education often came first. Although she was a mathematical prodigy, she spent most of her time preparing lectures rather than authoring publications, and writing grants to help fund outstanding students rather than her own research. She typically taught for 15 hours each week in addition to the time she spent preparing courses and mentoring students.

Browne is also responsible for setting up the first computer center at a historically black university, enabled by her successful application for a $60,000 grant from IBM in 1960. Additionally, she was known for giving her own money to students for tuition, food, and conferences. After she died, NCCU established the Marjorie Lee Browne Trust to continue her efforts.

Browne's incredible selflessness fueled an entire generation of mathematicians.

5. She advanced the pursuit of pure math

There are few people who speak about mathematics as elegantly as Marjorie Lee Browne did. She believed that math should be done for pure intellectual pursuit, defining a mathematician as someone who “appreciates the beauty, power, and eloquence of mathematics as one of the greatest art forms.”

Not surprisingly, then, Browne’s work was largely on abstract math. She explored the fundamental properties of shapes, a field known as topology. Her biggest contribution, “A Note on the Classical Groups,” is three pages of intense mathematical proof about the geometry of fundamental algebraic objects.

Browne worked at NCCU until she retired in 1979. She passed away just several months later, leaving an important legacy for black women in math, and the field of math at large. Looking back on her life, Browne noted, “If I had to live my life again, I wouldn’t do anything else. I love mathematics.”
