It was only 25 years later, in 1917, that the university gave its first civil engineering diploma to an African-American. For quite a while throughout history, engineering was almost entirely the domain of white men. Although Caucasian males still dominate the profession in the U.S. (only 5 percent of engineers are African-American, only 13.4 percent are women of any race, according to one 2011 report), it's important to recognize the significant legacies that Black men and women have created in the field [source: Koebler].
