Barron Hilton died at the age of 91 on Thursday.

He left 97% of his estate to the Conrad N. Hilton Foundation.

That takes the foundation from $2.9 billion to $6.3 billion.

Before the hotel business, he made his money in orange juice products, an oil company, the American Football League and an aircraft-leasing business.

He spent 30 years as the chief executive officer of Hilton Hotels.

The Conrad N.Hilton Foundation is a non-profit that invests in 7 programs: Catholic sisters, disaster relief and recovery, foster youth, homelessness, hospitality workforce development, safe water and young children affected by HIV and AIDS.
