Davidson, Jo (1883-1952), American sculptor, born in New York City. He studied sculpture at the Art Students League in New York City and the École des Beaux-Arts in Paris. Working in a variety of materials, including terra-cotta, marble, and bronze, he sculpted portrait busts in a realistic, strongly modeled and psychologically perceptive style. His engaging personality aided him in understanding and winning the cooperation of his subjects. Davidson's portraits of such contemporary notables as Woodrow Wilson, Franklin D. Roosevelt, Anatole France, Marshal Foch, and Albert Einstein won him an international reputation.
