Perky Cambridge-based explorer and historian Huw Lewis-Jones blew some much-needed levity into the day with his illustrated talk on the 1953 "conquest" of Everest, using George Lowe's remarkable photos from that expedition.
Like Sir Edmund Hillary, Lewis-Jones hates the word conquest, a word which cannot apply to a mountain. But that was the language of the 1950s.
Lewis-Jones got to know Lowe briefly before his death last year, saying when he visited his home in England, the umbrella stand in the hall held the very ice-pick used in the ascent.
The photos, in colour and black and white, were extraordinary, capturing the friendship between Hillary and his friend, and intimate moments like Lowe cutting Sir Ed's hair.
Their team of sherpas were rightly honoured in the photos; like today, mountaineering teams just could not manage without them.
