A. W. E. B. Du Bois

Explanation:

In Feb. 1919, nearly two decades after the 1900 conference, the first Pan-African Congress took place, and once again DuBois was at the center of its proceedings.

in mcculloch v. maryland (1819) the supreme court ruled that congress had implied powers under the necessary and proper clause of article i, section 8 of the constitution to create the second bank of the united states and that the state of maryland lacked the power to tax the bank.

gibbons v. ogden, (1824), was a landmark decision in which the supreme court of the united states held that the power to regulate interstate commerce, granted to congress by the commerce clause of the united states constitution, encompassed the power to regulate navigation.
