Business historian Juliet E. K. Walker refers to the era from 1900 to 1930 as the "golden age of black business" where "leading black capitalists . . . reflected their success within a black economy, which developed in response to the nation's rise of two worlds of race."4 African Americans who attended HBS during this time went on to make significant contributions in diverse fields and in their communities. Norris B. Herndon, for example, played a pivotal role in his family's insurance company, one of the largest African American owned businesses in Atlanta. H. Naylor Fitzhugh served as an influential professor at Howard University and assumed a senior executive position at the Pepsi–Cola Company. The accomplishment of other graduates such as Benjamin Tanner Johnson and Monroe Davis Dowling were deeply felt in both the private and public sectors. From 1915 to the founding of the African-American Student Union in 1968, however, fewer than 50 African American students had attended HBS.
