Hans Rausing

Hans Rausing's father founded packaging giant Tetra Laval in 1944. He and his brother Gad inherited the business in 1983, the year their father died. Rausing, who moved to the U.K. in the early 1980s to avoid punitive Swedish taxes, sold his share to Gad for an estimated $7 billion in 1995. The 6'8" tall, Russian speaker and collector of vintage cars now resides on a 900-acre estate in the village of Wadhurst in East Sussex where he breeds deer and wild boar. He also owns land in New Zealand, homes in Barbados and London, and has an investment in Ecolean, a producer of environmentally friendly packaging material. His Hans Rausing Endangered Languages Project at the University of London supports research, training, and archiving of disappearing languages. He has also contributed to the British conservative party, while his daughter Sigrid donates to liberal and human rights groups. His daughter-in-law died of a drug overdose in 2012. His drug addict son, Hans-Kristian, hid her body in a bedroom for eight weeks. Hans-Kristian was released from rehab in fall 2013, and has since re-married.

Tetra Pak billionaire Hans Rausing was seen at Royal Ascot today in one of his first public outings since his marriage to his new wife.

The 52-year-old was photographed in top hat and tails outside the Royal Enclosure at the famous racecourse, hand in hand with Christie's art expert Julia Delves Broughton.

Mr Rausing married Ms Delves Broughton last year after his first wife, Eva, died in 2012 as a result of cocaine abuse. Her decomposing body was found at their £70million Chelsea home several weeks later.

Mr Rausing - whose health looked vastly improved from the time of his ex-wife's death - attended on the same day as a host of Royals, including the Queen, the Duke of Cambridge, Prince Charles, the Duchess of Cornwall, Prince Harry and Princess Beatrice.

The Royals arrived by carriage ahead of an exciting day's racing, including the Queen Anne Stakes, the Queen Anne Stakes and the St James's Palace Stakes.

Mr Rausing, who lives in London and is worth an estimated £5.4billion, is the grandson of the Swedish founder the lucrative food packaging firm in 1951.

He married his new wife in front of just 60 guests at private ceremony in July last year, but celebrated with a large party at prestigious venue One Mayfair in November.

The former heroin addict first met Ms Delves Broughton in 2002, but is thought to have re-kindled the relationship after he entered a psychiatric hospital following his former wife's tragic death.

American-born Eva had died from an overdose, but Mr Rausing had hidden her body under a mound of bin bags and bedding for two months while maintaining a pretence to servants that she was still alive.

Rausing was convicted in July 2012 of preventing her lawful burial and handed a ten-month suspended jail term.

The judge at Isleworth Crown Court said Mr Rausing was a tragic warning of the 'utterly destructive' effects of drug abuse.

Private benefactor Mr Rausing, who has given tens of millions of pounds to charities including The HALO Trust – which removes land mines left behind in wars – museums and veterans' foundations, first met Ms Delves Broughton at Christies in 2002.

He and Eva had gone to lunch at the auction house, where Ms Delves Broughton began working as a secretary 18 years ago.

She quickly rose through the ranks, working in Old Masters, then the Valuation Department, before becoming a senior director working for Lord Linley in the Chairman's Office.

They then met again in 2006 when Hans, a serious art collector, called Christie's in to make a valuation at his home in Belgravia.
