John Mayston Béchervaise OAM, MBE (11 May 1910 – 13 July 1998) was an Australian writer, photographer, artist, historian and explorer. He is especially notable for his work and achievements in Antarctica. Béchervaise was married to Lorna Fearn Wannan; the couple had one son and three daughters. His family had come from Jersey in the 19th century where there is still a Bechervaise Lane.
Béchervaise was educated in Melbourne. He joined Geelong College in 1935 in order to establish a program of outdoor activities for the boys. During the years of the Second World War he studied art history at the Courtauld Institute of Art in London, but returned to Geelong College after the war.
In January 1949 he led a mountaineering expedition of the Geelong College Exploration Society to climb the hitherto unclimbed 1224 m Federation Peak in Tasmania. He also led the first party to land on Tasmania's most northerly point, rugged Rodondo Island in Bass Strait, 10 km off the coast of Victoria.
As well as contributing to the development of outdoor education in Victoria, he was for many years the assistant editor of the Australian magazine Walkabout.
In the 1950s Béchervaise joined the Australian National Antarctic Research Expeditions (ANARE). He served as field leader on Heard Island in 1953, leading an unsuccessful expedition to climb the 2745 m Mawson Peak of the Big Ben massif, the highest peak on Australian territory.
He also served as station leader at Mawson Station, Antarctica in 1955 and 1959. From there he led field trips of up to 600 km inland, exploring MacRobertson Land and the Prince Charles Mountains region. He was awarded the Polar Medal for this exploration work.
Béchervaise visited American Antarctic bases in 1966 as an Australian observer with Operation Deep Freeze.
Béchervaise Island (or 'Bech' to locals), was named on 1 January 2000 in his honour. It is the largest, central island of the Flat Islands, about 2 km WNW of Mawson Station.
Béchervaise was a highly respected teacher at Geelong Grammar School during the 1960s and early 1970s. He gave many lectures detailing adventures in Antarctica as well as similar escapades in Europe, an altogether inspirational teacher for those lucky enough to be his students. For three weeks in Lent 1963 when he went to the Antarctic islands on the Magga Dan, his lessons were taken by a British student Peter Bottomley, now Sir Peter Bottomley MP.
(His great-great-grandfather who came from Jersey and had the same name received the 1818–1855 British Arctic medal and published an anonymous memoir Thirty-Nine Years of a Seafaring life by An old Quartermaster in 1839. (Copies are in the British Library and Caird Library in Greenwich). Some sources misspell his name Berchervaise).
Béchervaise wrote numerous articles in Walkabout, the Victorian Naturalist and elsewhere. Some of his published books are:
