Olle was born in Sweden and is currently lives there. Formerly a teacher, he left the profession in order to write, photograph, play jazz and travel. He has travelled extensively in the Atlantic sector of the Arctic, including the Northwest Passage, Greenland and Svalbard. Since 1991 he has spent the northern winter seasons in his favourite area: Antarctica, sharing the migration route of the Arctic tern, always heading for summer, in the North as in the South. In Antarctica he has been an expedition leader, naturalist and lecturer for different companies

He admits being infected by the Polar bug, defined by the early explorers as "if you have ventured into the ice once, you will always long to come back." He has also worked as a naturalist guide, lecturer and zodiac driver along the coasts of Europe, around the British Isles and in the Baltic. He has backpacked parts of Asia and participated in a tree plantation project in Kenya. Together with his friend Stefan Lundgren, he has published “Antarctica - in the interest of all mankind” (1990), currently only in Swedish, and appointed the Panda Book of 1991 by the Swedish section of WWF. More recently Olle and Stefan have completed Svalbard - the Land beyond the North Cape (in English), and between 1998 & 1999, they completed another book in English titled "Antarctica - a souvenir book from the 7th continent". He has produced several articles for magazines and papers, and also given lectures and slide-shows on the Polar areas around Sweden, Denmark and the USA.
