In his youth, he attended the Royal Academy of Painting and Sculpture in Paris, France. In 1776, he traveled to America to serve the Continental Army in its struggle against the British.
An outspoken human rights advocate, he included in his will instructions that his American fortune be used to assist, educate, and free slaves.

He was a contemporary and good friend of third United States President Thomas Jefferson.
