Frederick Franck, Dutch-American painter, sculptor, and author (b. 1909)
Frederick Sigfred Franck (April 12, 1909 in Maastricht, The Netherlands – June 5, 2006 in Warwick, New York, U.S.) was a painter, sculptor, and author of more than 30 books on Buddhism and other subjects, who was known for his interest in human spirituality. He became a United States citizen in 1945. He was a dental surgeon by trade, and worked with Dr. Albert Schweitzer in Africa from 1958 to 1961.His sculptures are in the collections of the Museum of Modern Art, the Whitney Museum of American Art, the Fogg Art Museum, the Tokyo National Museum, and the Cathedral of St. John the Divine.

His major creation was a sculpture garden and park adjacent to his home in Warwick, New York, which he called Pacem in Terris ("Peace on Earth"). In 1959, he and his wife, Claske Berndes Franck, purchased the six-acre property, the site of an old grist mill which had become a dumping ground, for $800. They opened Pacem in Terris to the public in 1966. Dr. Franck dedicated it to Dr. Albert Schweitzer, Pope John XXIII, and the Buddhist teacher D.T. Suzuki. More than 70 sculptures adorn the property, which is now operated by a nonprofit foundation.
