Ted Turner: US$2.3 billion

Turner, media magnate and founder of CNN, has signed the The Giving Pledge – a campaign to encourage extremely wealthy people to contribute most of their wealth to philanthropic causes. He is known to have donated US$1 billion to the United Nations.

He started work from an early age at his father’s insistence, who owned a billboard business called Turner Outdoor Advertising, which he took over in 1963 after his father’s death. He made US$7.5 billion in 1996 when he sold Turner Broadcasting to Time Warner, according to The New York Times.

Turner, who has been married and divorced three times (his most famous marriage was to actress Jane Fonda), has five children who will not be inheriting all of his vast net worth. According to CNN, Turner was named “among 40 billionaires pledging half or more of their fortune to charity through The Giving Pledge campaign”.

The CNN founder is also the second-largest landowner in the US, with an estimated 810,000 hectares (two million acres) of land. He uses a lot of his land for ranches to re-popularise bison meat, amassing the largest herd in the world. He also has his own steakhouse chain called Ted’s Montana Grill that serves, well, bison.

Reed Hastings: US$5.7 Billion

He spends his free time much like the rest of us do – taking yearly holidays and watching Netflix in the evenings. He also enjoys spending time with his wife Patricia Quillin and their two children, and taking care of his pets, which include a couple of Nigerian dwarf goats.

George Lucas: US$7.3 billion

Soon after the Star Wars creator sold his company Lucasfilm to Disney, he announced that a major part of his wealth will go into educational philanthropy. The sale of his company brought him a profit of about US$4 billion.

He once said in a statement: “It [education] is the key to the survival of the human race. We have to plan for our collective future – and the first step begins with social, emotional, and intellectual tools we provide to our children.”

Lucas has also pledged to give half of his fortune to charity as part of The Giving Pledge effort.

Lucas has four children. Three of his children are adopted, and the fourth child was born out of surrogacy. To continue his goal to help in educating children, he also created The George Lucas Educational Foundation.

Laurene Powell Jobs: US$22 billion

Laurene Powell Jobs inherited a considerable fortune after the death of her husband Steve Jobs, the founder of Apple. Steve Jobs’ net worth was valued at $10.2 billion at the time of his death in October 2011.

Laurene and Steve have three children together, as well as his daughter Lisa Brennan-Jobs from a previous relationship. According to the International Business Times, Lisa revealed that she and her siblings did receive an inheritance from their father that numbers in the millions, but she is not involved in the allocation of the rest of his wealth.

Warren Buffett: US$100.8 billion

Warren Buffett famously said he wants to give his children “just enough so that they would feel that they could do anything, but not so much that they would feel like doing nothing”.

The CEO of Berkshire Hathaway also founded The Giving Pledge campaign alongside Bill Gates.

He has also pledged to give more than 99 per cent of his wealth to charity, leaving relatively less for his children. However, each of them has a US$2 billion foundation funded by their father, according to the The Washington Post.

Bill Gates and Melinda Gates: US$133.2 billion

Individually, Bill Gates is worth US$129.6 billion while his ex-wife Melinda Gates is worth US$5.7 billion.

The divorce will leave the Bill and Melinda Gates Foundation, which they started in 2000 unscathed, but what about their children’s inheritances?

However, this could change after the divorce. According to Page Six, divorce experts say that Melinda’s divorce filing hints that she could change her three children’s inheritances. Page Six adds that Melinda has “well-known trust and estate lawyers involved in the case”, and that it’s “most unusual for trust and estate lawyers’ names to be listed on a divorce filing”.

In 2015, when Zuckerberg and his wife Priscilla Chan welcomed their first daughter Max, they announced in an open letter that they would be giving away 99 per cent of their company shares over the course of their lifetime to a foundation they created to “promote equality for all children in the next generation”. The couple also has a second daughter, August.

Other noted millionaires sharing the same thoughts …
