Technology and the International Institute for Conservation. C. F. Louis de Wild Carel de Wild's son C. F. Louis trained with his uncle Derix for much of his youth, eventually establishing his own restoration practice. Immigrating to the United States from The Hague after his father's death, he opened an independent conservation studio in New York City in 1929. He worked in conjunction with American museums like the Metropolitan Museum of Art, the National Gallery of Art, and, like his father before him, the Frick Collection. Notable paintings he restored include the Alba Madonna and multiple works by Piero della Francesca. He retired from his conservation practice in 1969, and passed away in 1987 at the age of 86.
