Harold Earle Riddiford
In 1951 Riddiford joined Shipton’s party on the Everest reconnaissance expedition to the south approach, and in 1952 went to Cho Oyu, helping to organize that expedition.
After service with New Zealand Army Intelligence, Riddiford obtained a law degree from Canterbury University. A passionate and determined mountaineer, he took part in several important climbs of new routes in New Zealand in 1947–49. He initiated, organized, and led the first all-New Zealand expedition to the Himalayas, making the first ascent of Mukut Parbat in 1951.
In his last 20 years he was engaged in running and improving an extensive sheep and cattle property originally owned by his grandfather.
