Leny and Oskar Bider were the brightest shining examples of the Helvetic jeunesse dorée. Oskar was celebrated as a pioneer in aviation and for being the first pilot to fly over the Alps and survive. His sister, Leny, a diva-like actress (‹Frühlingsmanöver›, ‹Der Bergführer›), had fulfilled the dream of acting against all odds and being temporarily exiled to the imprisonment of boarding school. Oskar, born in 1891, and his sister, Julie Helene “Leny”, who was three years his junior, forged an intimate sibling relationship. He was her constant companion, her pride and joy, her famous pilot and trusted advisor. She was the beautiful planet he orbited. His wise, mysterious sister. A fun-loving, much sought-after young lady. They have both hung from a climbing rope together in the mountains, rowed in a boat, flown over Switzerland and ridden over land – and all preferably at dawn, when in the thick mist hangs over the valley.
