We've previously referred to the allure of collectibles associated with explorers on our blog - one of the examples being the diary of Captain Scott ahead of his doomed Antarctic expedition.
Now Bonhams is set to offer what is perhaps an even more poignant set of papers: The first of the farewell letters written in the Antarctic by Captain Robert Scott as he realised that he and his team would not survive.
The letter is for sale at Bonhams Polar Sale in London on 30 March 2012. It is estimated to make £100,000-150,000.
The letter, which was found on Scott's body in November 1912, was written on the 16th March of that year -almost exactly a century before the auction - to financier Sir Edgar Speyer, honorary treasurer of the fund-raising committee for the ill-fated trip. In it, Scott expresses his great concerns for his family and the families of his companions and asks that the nation provide for their future.
Sensing that the position was hopeless, Scott wrote, "I fear we must go...but we have been to the Pole and we shall die like gentlemen - I regret only for the women we leave behind. If this diary is found it will show how we stuck by our dying companions and fought this thing out to the end.
"We very nearly came through and it's a pity to have missed it but lately I have felt that we have overshot our mark - no-one is to blame and I hope no attempt will be made to suggest that we lacked support."
The letter was at one time owned by the famous American polar explorer, Rear Admiral Richard E Byrd, and was presented to him at a dinner in his honour in 1935 by Sir Edgar Speyer's widow.
The recipient of the letter, Edgar Speyer, was a well known business, political and philanthropic figure before the First World War. He had played a major role in raising funds for Scott's expedition and Mount Speyer in the Arctic was named in his honour by Scott.
American born to a wealthy German family, Speyer became a British national at the age of 30 in 1892. A great patron of the arts, particularly music, he personally funded the Proms for many years and single-handedly secured their long term future. Richard Strauss dedicated his opera Salome to him.
Scott need not have worried about the future of the team's widows and orphans. Once the contents of his final letters became known, there was a huge outpouring of public sympathy resulting in enough money not only to pay off the expedition's debts but also to settle annuities on the families of those who died and to endow the Scott Polar Research Institute.
Interest in the great Polar expeditions remains strong, and we're proud to have a signed letter from Scott's rival Ernest Shackleton, written to his wife less than a year before his death due to a heart attack.
