David Hempleman was born in Moredon, Swindon in October 1956. Following his parents' divorce, he moved with his mother to Stoney Littleton near Bath, and when she remarried, took his stepfather's surname Adams. 
He took part in the Duke of Edinburgh's Award scheme at school, then pursued business studies at college in Manchester and at Bristol Polytechnic. At the same time, he started climbing with fellow student Steven Vincent.
In 1984, he successfully completed a solo expedition to the Magnetic North Pole without dogs, snow mobiles or air supplies. Also he led the first team in 1992 to walk unsupported to the Geomagnetic North Pole.[clarification needed] This was described in the book A Race Against Time. In 1996, he completed a solo unsupported expedition to the South Pole on 5 January, sailed to the South Magnetic Pole on 19 February, and led a team of novices to ski to the Magnetic North Pole on 15 May. The book Toughing it Out describes David's first 20 years of adventuring.
In 1998 he joined Norwegian Rune Gjeldnes in an attempt to reach the Geographical North Pole, the final leg of his Grand Slam attempt, which he described in a book called Walking on Thin Ice. He also became the first man to fly a balloon over the North Pole in 2000, a trip that emulated the ill-fated attempt by Salomon August Andrée, a Swede, to fly to the North Pole in the 19th century and which he also described in a book called At The Mercy of the Wind.
He has made thirty Arctic expeditions and has reached the various Poles a record 14 times.
In July 2004 he and co-pilot Lorne White flew a single engine Cessna from Cape Columbia in the north of Canada to Cape Horn at the southern tip of South America, covering 11,060 miles and arriving on 23 July after 12 days. In June 2005, Hempleman-Adams staged the world's "highest" formal dinner party. Hempleman-Adams, Alan Veal, and fellow adventurer Bear Grylls ascended to 24,262 feet in a hot air balloon. Grylls and Veal, wearing formal attire, then climbed down to a dinner table suspended 40 feet below the balloon and dined on asparagus, salmon, and summer fruits, and finally parachuted down to earth. His daughter Alicia Hempleman Adams,at aged 8, became the youngest person to stand at the North Pole and in April 2005 aged 15 she became the youngest person to traverse Baffin Island. In January 2007, Hempleman-Adams broke the quarter-century old world small sized hot air balloon altitude record, by ascending to 9,906 meters over Alberta, Canada; beating the previous record of 9,537 metres set by Carol Davis in New Mexico.
In July 2007 Hempleman-Adams crossed the Atlantic in the smallest helium balloon to break the record for that particular class of balloon flying this distance. His aim was to land the balloon in Ireland but he was blown over to England by strong winds.See Toshiba Challenge website.
In September 2009 he broke the endurance record for a flight using the smallest man-carrying helium balloon. He flew 200 miles from Butler, Missouri, to Cherokee, Oklahoma, in 14 hours and 15 minutes using the class AA-01 balloon. The previous record was an eight hours and 12 minutes flight undertaken by American Coy Foster in March 1983.
To coincide with the 100th anniversary of Scott's expedition to the South Pole,The Heart of the Great Alone was published with the Royal Collection. It brings together a selection of the astonishing photographs taken by Herbert Ponting and Frank Hurley with commentary and narration by David.
In May 2011 he led the Iceland Everest Expedition on the North Side of Everest. £1.2 Million was raised for their chosen charity.
In October 2011, along with co-pilot Jon Mason, David won the Americas Challenge Balloon race and in doing so set a new duration record for the race. They are the only British team to win both the Gordon Bennett Balloon Race and Americas Challenge.
