Ronald Feldman, who for nearly 50 years oversaw one of New York’s most consistently political, forward-looking art galleries, died on Dec. 20 at his home in Chappaqua, NY. He was 84.

Trained as a lawyer and deeply interested in politics, Mr. Feldman, at his Ronald Feldman Gallery in SoHo, exhibited artists who pushed boundaries with work that almost always had a political slant, including themes focused on women’s rights, the environment, totalitarianism, identity and war.

Warhol was a frequent visitor, often asking Mr. Feldman a question: “Do you have an idea for me?” Mr. Feldman eventually came up with an idea that appealed to Warhol, resulting in “Ten Jews of the 20th Century,” silk-screen portraits published in 1980 and first exhibited at Manhattan’s Jewish Museum.
