About Forrest Mars, Jr.,_Jr.

Forrest Edward Mars, Jr. (born August 16, 1931) was the eldest son of Forrest Mars, Sr. and the grandson of Frank C. Mars, the founder of Mars, Incorporated, the confectionery company. In March 2015, Forbes estimated his wealth to be $26.8 billion up from US $11 billion in March 2010. As of October 2012 the Bloomberg Billionaires List ranks Mars as the 31st richest man in the world with an estimated net worth of 20.1 billion.

Early life

Mars graduated from the Hotchkiss School in Lakeville, Connecticut in 1949 and Yale University.

Public activities

As owner of the Diamond Cross Ranch, an 82,000-acre (33,000 ha) parcel along Montana’s Tongue River and on the northern end of the Powder River Basin, Mars has been active in opposing the development of his part of what's been called the "most productive coal and natural gas fields in the nation." Companies that hold the oil and gas leases to his land, rights originally made possible by the Stock-Raising Homestead Act and the Mineral Leasing Act, are seeking to exercise those rights on his ranch. Mars is reportedly concerned about the large amount of water that energy exploration and production projects consume, water needed by his ranch.

Mars and his ex-wife donated the funds that made it possible for the Colonial Williamsburg Foundation to reconstruct an 18th-century coffeehouse in Colonial Williamsburg.

The ex-couple made significant contributions to the privately owned governing body for Fort Ticonderoga, though a falling-out between Executive Director Nicholas Westbrook and Mrs. Mars led to her resignation from the board and the end of the then-couple's financial support.


According to Forbes magazine as of 2010, he was the 52nd richest person in the world, the 26th richest American, and the richest Virginian.


Mars married Virginia Cretella, born 1929/1930 (age 86–87). They have four children: Victoria Mars, Valerie Anne Mars, Pamela Diane Mars and Marijke Elizabeth Mars.

He divorced Virginia in 1990 to marry Deborah Adair Clarke. He divorced Deborah Adair Clarke in 2010.
