Who organized the 1941 exhibition afro-american art on both continents which included works of romare bearden and delaney brothers?

The 1941 exhibition you're referring to is likely the "First Exhibition of Contemporary Negro Art," which was organized by Alain Locke, a prominent African-American philosopher and writer.

This exhibition, held at the New York World's Fair, aimed to showcase the artistic achievements of African American artists both in the United States and abroad. It included works by Romare Bearden, the Delaney Brothers, and other notable artists of the time.

While the exhibition is often cited as a key moment in the development of the Harlem Renaissance, it's important to note that it wasn't the first exhibition dedicated to African American art. There were earlier exhibitions in the 1930s, though Locke's exhibition is credited with being a significant event in the wider artistic landscape of the time.
