As dawn breaks over the National Mall, the Hirshhorn Museum emerges as a standout example of modernist design among Washington DC's historic landmarks. Its unique circular shape sets it apart from the traditional architectural styles of nearby monuments, marking a significant shift towards the avant-garde. The museum is a gateway to the world of contemporary art. Few visitors would imagine the incredible backstory of the museum’s founder, a rough stock operator turned mine promoter who became the undisputed king of uranium at the height of the Cold War.
