Karl and Gertrude arrived in Sydney in May 1939 proceeding to Brisbane in July so that Karl could commence work for architects Cook and Kerrison. From the time of their arrival until their deaths the Langers dedicated themselves to a great variety of civic and professional activities. Their combined efforts greatly influenced the development of the arts and design in Queensland especially through such organisations as the
Queensland Art Gallery Society, the
Australian Council for the Arts and the Vacation Schools of Creative Art in which they fulfilled key roles over many years. As one of the earliest of
Australia's women newspaper art critics Gertrude wrote for
The Courier Mail from 1953 until her last review, published on the day she died, 19 September 1984. She was a foundation member of the
International Association of Art Critics and was president of the Association's Australian Division from 1975 to 1978. Through her work with the Gallery Society and her personal donations of art works including drawings by Karl she exerted her influence on the collection of the Queensland Art Gallery. Their home,
Langer House, in
St Lucia was designed by her husband Karl. The house was sold after the death of Gertrude Langer in 1984. It is listed on the
Queensland Heritage Register. ==Honours==
