Andre Zlattinger is a senior director in the British paintings department at Sotheby’s and, as head of Scottish sales, handled record-breaking auctions such as Jack Vettriano’s The Singing Butler. In his spare time he is a keen mountaineer and last month he was on the edge of Everest’s “death zone”, preparing to strike out for the mountain’s summit on an expedition to raise funds for the hospital where his mother was treated for cancer before her death.He’s a regular visitor to the Highlands and Islands, and has also climbed in the Alps, the Andes and the Himalayas. On 1 May, Sotheby’s latest Edinburgh sale netted more than Â£4 million. From the Everest base camp, a delighted Mr Zlattinger said it showed the “real depth” of the Scottish market and “renewed interest in the Glasgow school“. He will be back in Scotland for his firm’s sale at Gleneagles in August.
