Edmund Hillary
Sir Edmund Percival Hillary (20 July 1919 – 11 January 2008) was a New Zealand mountaineer, explorer, and philanthropist. On 29 May 1953, Hillary and Nepalese Sherpa mountaineer Tenzing Norgay became the first climbers confirmed to have reached the summit of Mount Everest. They were part of the ninth British expedition to Everest, led by John Hunt.
Musa Ibrahim
"Nepal Parbat, a" list of the Mt Everest toppers published by the Nepal's Ministry of Tourism and the Nepal Mountaineering Association (NMA) did not include the name of Ibrahim. The list names MA Muhith and Nishat Majumder as the first Bangladeshi male and female to have climbed Mt Everest successfully. MA Muhith and Nishat Majumder also expressed doubts about Ibrahim’s claims. However, Ibrahim said that there had been a conspiracy against him and NMA was influenced by the conspirator. The issue over the claim was moved to a court in Dhaka. O'Mahoney, who had followed Ibrahim towards the Everest summit, claimed that he saw him at the third step of the route, the last barrier to the Everest summit.
