Shambhu Tamang

1973: Italian Expedition. Another huge expedition with sixty-four members led by Guido Monzino. Helicopters are used to shuttle equipment past the Khumbu Icefall and one hundred Sherpas are also employed. Eight climbers succeed via the South Col Route, including 16 year old Sambhu Tamang of Nepal. It is later revealed that Sambhu was actually 18.
In 1960, Chu Yin-Hua claimed to have reached the Summit on May 25th at the age of 25 years 55 days old. His summit, along with all the 1960 Chinese Summits were disputed for years. No Summit picture exists to this day. In 1965 Sonam Wangyal on May 22nd claimed the record at 23 years 134 days old.
Then things get real interesting. Sambhu Tamang summits on May 5th, 1973. Many report, for years, record his age to be 16 years old. Many still report him to be have been 16 when he reached the summit! It is now believed he was around 18. If you check different sources you will find ages from 16-19! Interesting Sambhu summits a second time on 8/28/1985, 12 years later. Possibly the longest time between summits, but let's not go there either.
Sambhu Tamang was born in 1955. He currently lives in Kathmandu, Nepal. He summited Everest a second time on August 28, 1985. The TAMANGS, are people who are alleged to be one of the oldest inhabitants of the hills north of Kathmandu. The areas of Lantang, Ganesh Himal and Helembu and the surrounding area comprising the rim of the valley. The TAMANGS were part of the 1953 Everest expedition lead by Sir Edmund Hillary and were once again placed in the history of Everest, when SAMBHU TAMANG, the 18 years old boy became the YOUNGEST person (at the time) ever to reach the summit of EVEREST in 1973.
