For instance Alexander Animalu a Nigerian scientists while not personaly winning a physics Nobel himself has produced cited research that has allowed others to win Nobels in physics. Which is uncommon for blacks, this is what they need more of in order to win.
Prizes outside Nobel awards do not need such academic networking which is why in other scientific awards like the Von Neumann Prize does feature Black recipients.
