London, Oct.1 : A BBC producer has expressed his determination to prove that George Mallory, and not New Zealander Edmund Hillary and his Nepali Sherpa Tenzing Norgay, was the first to reach the summit of the over 29,000 feet high Mt. Everest.

Graham Hoyland will tell the Royal Geographical Society this week how George Mallory and Andrew Irvine were the first men on Everest in 1924.

Hillary and Tenzing reached the summit in 1953.

Mallory's frozen body was recovered in 1999, 75 years after he started out on his expedition.
