Women and Minorities in Mathematics Incorporating Their Mathematical Achievements Into School Classrooms Evelyn Boyd Granville: Complex Solutions to Real-Life Problems Sarah J. Greenwald Appalachian State University In 1949 Evelyn in mathematics faced the "double Boyd Granville whammy" of racism and sexism. became the second Like blacks, women were not black woman we considered to have the mental skills know of to earn a necessary for advanced Ph.D. in mathematical inquiry. For all mathematics. women, and especially for black Granville is well women, the field of mathematics was known for essentially shut tight.

Her wonderful life. husband was a deputy superintendent of public schools. After her retirement she First Black Women Mathematicians chaired the DC Board of Education, where The earliest black women who studied she had a central role in the integration of mathematics faced many barriers: DC public schools. In 1976, she reflected: Over the years, black women who I have been a mathematics scholar might be disposed to pursue a career all my life, through high school, through college, and then to get my hiring committee discovered that she was doctor’s degree in mathematics…. I black, “they just laughed” and the dean said didn’t expect to get my doctor’s they “would have to change the plumbing” degree, never, in mathematics, but I (Murray, 2000). At the national level, she wasn’t surprised in other areas advocated for the integration of mathematics because I enjoyed it so much. conferences and she was an outspoken critic (Kenschaft, 2005) of discrimination (Inniss and Bozeman, 2006). She accepted a position at Fisk Evelyn Boyd Granville University, a historically black institution, Evelyn Boyd Granville also grew up in but after two years at Fisk, she moved to Washington, DC.

Her mother and returned to the academic world in 1967 to aunt made many sacrifices in order to help concentrate on teaching: her make up the difference between her How do you teach the beauty of scholarship and her bills (Kenschaft, 1981). mathematics, how do we teach them Granville earned degrees in mathematics to... solve problems, to acquaint and physics from Smith.

That's the dilemma we face. (O’Connor & Robertson, 2001) Granville spent a year at a research She married again in 1970, to Edward V. postdoctoral position. She then interviewed Granville, a real estate broker, and has for jobs but she encountered discrimination. remained happily married. At one school, she later found out, when the She has received numerous honors and Granville could be mentioned in that awards, including an honor from the context. National Academy of Sciences in 1999. Granville has retired a number of different Activities Related to her NASA Work times, but she still visits schools and Evelyn Boyd Granville loved working for universities, and seems to be drawn to NASA’s space programs: continue her efforts to show students the I can say without a doubt that this beauty of mathematics. In the summer of was the most interesting job of my 2007, she taught a “Math Warm-Up” class lifetime - to be a member of a group for students entering grades 6-7 (Granville, responsible for writing computer 2007). Just as Granville was inspired by her programs to track the paths of teachers, she continues to inspire students. vehicles in space.

In fact, NCTM and work to be done. As of 1999, it was NASA partnered to produce aerospace estimated that there were only 40 total activity books that align with the standards African American women who had for Pre K-2 (Hynes & Blair, 2005), grades 3- earned doctorates in mathematics, and 5 (Hynes & Hicks, 2005), grades 6-8 (Hynes only 20 more black women & Dixon, 2005), and grades 9-12 (House & mathematicians elsewhere in the world Day, 2005).

Teachers of grades 5-6 can even access Activities Related to her Thesis Work lesson plans on trajectory and projectile Granville says that her thesis was not at all motion designed for them by grade 9 impractical, since it prepared her well for students (Leaf, 2008). everything in life and work (Clayton, 2000). Curious students can examine Granville’s Students interested in Granville’s orbital thesis abstract (Boyd, 1949), but the content computations can access an article detailing on Laguerre series in the complex domain is the contributions, procedures, and too advanced for school classrooms.
