My husband, George Spenceley, who has died aged 91, was a climber, photographer and lecturer.
In 1955-56, he was a member of a survey expedition to Antarctic South Georgia, where the Spenceley glacier was named after him. In 1957 during an expedition in the Jugal Himal of Nepal he was the sole survivor of an avalanche.
He was born in Harrogate, North Yorkshire. When George was a small boy, his father took him up Ingleborough, one of the highest mountains in the Dales. He pointed out some tents far below that belonged to members of the Yorkshire Ramblers Club and told George that one day he would be a member. George joined the club soon after the outbreak of the second world war, then a recently qualified RAF pilot.
After more than 40 wartime operations, he was shot down in 1942, in one of the early 1,000-plane raids over Germany. He spent several weeks in hospital, then three years as a prisoner of war. Returning home in 1945, he married Marjorie, with whom he had three sons, Julian, Adrian and Nicholas.
He became a geography teacher, but also continued walking, climbing and exploring, and turned his adventures into illustrated talks for schools and societies all over Britain.
After his divorce from Marjorie, we married in 1977 and settled in Oxfordshire. George continued his successful career as a lecturer, mainly during the winter months between September and April. Together we canoed the full length of the river Danube in 1979-80, followed by the Mississippi in 1984. At the age of 84, George became the oldest man to reach the Annapurna Sanctuary in the Himalayas.
He is survived by me and his sons.
