Charles Engelhard Foundation is a New York-based left-leaning grantmaking foundation that focuses on projects in education, medical, religious, wildlife, and conservation organizations. It was founded in 1954. Charles Engelhard’s five daughters are trustees of the foundation.
Charles Engelhard made his fortune in the platinum, gold, and silver business, which he inherited from his father. He expanded his empire across the world, with a successful location in South Africa.  His family had a sprawling estate in New Jersey, where Charles Engelhard and his wife lived with their five daughters. The family had champion show dogs and thoroughbred racehorses. At one point, the Engelhards owned over 300 horses across five countries, one horse being an English Triple Crown winner. Charles Engelhard established a business partnership with Harry Oppenheimer, the founder of DeBeers jewelry company. 
In 1955, a legislative contest to represent Somerset County in the New Jersey State Senate was held between two future billionaires, magazine publisher Malcom S. Forbes and Charles Engelhard, with Charles Engelhard being defeated.  Some believe that Engelhard was the inspiration for Ian Fleming’s 1959 book Goldfinger and the movie that followed.  Charles Engelhard died in 1971.
Charles Engelhard’s wife, born Marie Antoinette Jeanne Reiss and later to become known as Jane Engelhard, passed away in 2004. She was a socialite, philanthropist, and was known for her connections to political figures and donations to the White House (Christmas creche) and the Metropolitan Museum of Art. She assisted First Lady Jacqueline Kennedy to restore the White House and served on committees to preserve the White House from the Kennedy Administration through the presidency of George W. Bush.  She was a trustee of the Metropolitan Museum of Art from 1974 to 1981 and donated the Charles Engelhard Court to the Met’s American Wing in 1980.
