Prince Henry Charles Albert David Windsor, the second son of Prince Charles and Princess Diana, was born on September 15, 1984.
Dubbed "the happy prince" by Fleet Street editors, he seemed to have a gift for bringing fun and joy to those around him.

Princess Diana was determined to give William and Harry, seen with his pony, Smokey, at Highgrove, a normal upbringing.
The Queen has always been close to her grandsons.

Their childhood was full of cuddles.
On this occasion William and Harry had flown to join their parents on an official visit to Canada in October 1991.
The Princess often organised down-to-earth treats such as trips to amusement parks and the cinema.

Just a few days short of his 13th birthday Harry faced unthinkable grief when Diana died following a tragic car accident in 1997.
Flanked by his grandfather, brother, uncle and father, the Prince walked behind her coffin to pay his final respects on September 6.
Following his mother's death, his relationship with his father, whom he and William call 'Pa' grew even closer.
Charles steered him through some tricky teenage years, including a brush with drugs when he was 17
Diana's passing when he was 12 had affected him deeply, and the Prince vowed as an adult to carry on her work.
"Harry has inherited his mother's extraordinary empathy," a senior Palace official once said.
"He engages with children and young people."

After a gap year partly spent in Lesotho, Southern Africa, the Prince established a foundation there called Sentebale.
The name means Forget Me Not in the local language a tribute to his mother's charity work and, he said "a reminder to us all not to forget Lesotho or its children".
It targets the forgotten victims of the AIDS epidemic - the children left behind by sick parents.
His larger-than-life personality is key when it comes to raising money for charity.
When he joined a fundraising day in the City in competition with other celebrities, Harry came out on top helping close a deal for £15 billion – a record sum, a slice of which was donated to Sentebale.
He has also taken on her mantle in other respects, showing a close interest in her anti-landmine campaign.
In 2010, the Prince visited Mozambique to inspect mine clearance projects.
He followed his brother to the Royal Military Academy Sandhurst on May 8, 2005.
Describing his work in the Army, General Sir Richard Dannatt said the young Prince was a "credit to the nation".
Officer Cadet Wales graduated from Sandhurst in April 2006, and his passing out parade was inspected by his grandmother.
"Here is a face I recognise," said the Queen, provoking a broad grin from her grandson.
After five years serving as an officer, Harry was promoted to the rank of captain in the British Army in April 2011.
He was awarded the coveted Apache Badge, meaning he had completed the first stage of training as an Apache helicopter pilot.
The action-man Prince returned to Afghanistan in September 2012, serving four months as a pilot.
He went on a secret ten-week tour of duty in Afghanistan in late 2007.
After bravely serving on the front line, he was forced to withdraw because news of his presence was leaked.
His experiences in the military have made the soldier-Prince a staunch supporter of returning veterans.
One of his projects involved an Arctic trek with former servicemen for the charity Walking with the Wounded.
He was only able to take part for four days due to military committments. But the Prince was the first to congratulate the team when they reached the North Pole.
He told them via satellite phone that they were "showing off" by reaching the destination three days earlier than planned.
In 2014, he launched the Invictus Games, bringing together injured service personnel as a way of encouraging their rehabilitation.
Harry has become global star thanks to his compelling life story and charisma.
The public love his spontaneous personality - although it sometimes gets him in hot water too.
After the Rugby World Cup in France in 2007, he was pictured looking a little worse for wear the next day.
Then in 2012, high jinks involving a game of naked billiards before another army deployment were recorded on a phone and went viral.
He commands attention even in the presence of celebrities like Kanye West and Sean 'Diddy' Combs.
The rappers performed at Concert for Diana, a memorial on her birthday, 10 years after her death.
The royal wedding in 2011 when Harry was his brother's best man marked a new chapter in the royal family, pushing the younger members to the fore.
He enjoys an excellent relationship with his sister-in-law, who is very much part of the renaissance of the Windsor brand.
In recognition of his growing popularity and maturity the Queen personally picked Harry to represent her on a Diamond Jubilee tour.
The young Prince travelled to Belize, the Bahamas and Jamaica, where he cheekily challenged Usain Bolt to a race.
A year later the charmer generated Harrymania again on a tour of Australia, bowling over young and old alike.
Along with the Duke and Duchess of Cambridge he has established himself as one of the country's best loved figures.
