I believe that I have answered this question earlier. I find it gratifying to receive recognition for my work. What should not be forgotten is that millions of African students should be nurtured to become scientists and use their skills to develop the continent. White scientists often take credit for the inventions of black scientists. Black scientists are denied opportunities provided to white scientists.
Black scientists have to be twice as good to get half the credit they deserve.
Because Black scientists have to overcome racial discrimination to make their contributions, their inventions is testimony to the triumph of the human spirit over adversity.
