A look back at the life of Eva Rausing, who was found dead in her London home on Tuesday.
Eva Kemeny and Hans Rausing met in the privacy of a US drugs rehabilitation clinic, but went on to fight a public battle against addiction.
Born in 1964, Mrs Rausing was the daughter of millionaire Tom Kemeny, a former Pepsi Cola executive.
She married Mr Rausing soon after they met in the 1980s, and the pair went on to become society figures in London, living in fashionable Cadogan Place, Chelsea.
He was heir to the £5.4bn Tetra Pak drinks carton empire, and they became active philanthropists.
The couple, who have four teenage children, substantially supported a number of addiction charities, and she was a trustee of the Prince of Wales's charity, the Prince's Foundation for Building Community.
A spokesman for the charity Action on Addiction paid tribute to the support Mrs Rausing had given them.
"Everyone involved with Action on Addiction is devastated to hear the news of Eva Rausing's untimely death.
"Without any desire for public recognition, Eva has, through her wonderfully generous support of this and other charities, helped so many people for over 20 years. We offer our deepest sympathy to Eva's family at this time of great loss," the spokesman said.
The Rausings' affluent lifestyle was disrupted by their own problems with drugs.
They went from being a glamourous couple, attending society events, to being photographed looking gaunt and frail in recent weeks.
Police first took notice of them four years ago when Mrs Rausing was caught with drugs as she tried to enter the US Embassy in London for a function.
Documents revealed that Mrs Rausing, then 44, was carrying about 10g of crack cocaine, 2.5g of heroin and a quantity of diethylpropion, a banned stimulant and appetite suppressant.
A further drugs stash, containing diazepam, used to treat anxiety, was found in her Renault Clio car.
The couple's £5m Georgian five-storey town house was searched, and officers found 5.63g of crack cocaine, 2.9g of heroin and almost 52g of cocaine.
Mr and Mrs Rausing faced drug charges but were given conditional cautions instead, meaning the hearings did not go ahead.
Mr Rausing's parents and siblings said at the time that they were supporting the couple as they fought to overcome drug addiction.
In a statement they said: "The Rausing family are deeply saddened by Hans K's and Eva's situation, and the events leading up to their court appearance today.
"We hope with all our heart that Hans K and Eva can overcome their addiction and we continue to do what we can to help."
The Prince of Wales reportedly claimed she should be given "a second chance" as he stood by her during the investigation.
Mr Rausing's Swedish billionaire father, also Hans, created the Tetra Pak empire with his late brother, Gad.
The distinctive product revolutionised the packaging of milk and fruit juices worldwide.
The discreet Rausing family are one of Britain's biggest charitable donors, giving more than £150 million in the past few years, according to reports.
Mr Rausing is one of three children to Hans Rausing senior.
