Noel Leslie Macainsh was a poet, author, academic and translator born on 15 June 1926 in Horsham, Victoria. After serving in the Royal Australian Air Force during World War Two then working as a professional engineer, he pursued higher education at the University of Melbourne, earning a Master of Arts in 1965 and a PhD in Germanic Studies in 1967. He then joined James Cook University in North Queensland as a Reader in English in 1969, a position he held until his retirement in 1989. During this period he resided in Black River, north of Townsville.

Macainsh was a prolific writer, producing literary criticism on Australian poetry, literature and translations featured in anthologies, newspapers, and journals both in Australia and internationally. In 1991, he moved to Northern Italy, where he lived in Padenghe sul Garda until he died in 2012, survived by his wife, Camilla Bettoni, and his children, Gregory, Andrew and Rilka. His son, Gregory Macainsh, was a member of the band Skyhooks.

Ray Sumner, born Catherine Ray Martin on 21 March 1944, grew up in Townsville, Queensland. She attended the University College of Townsville (now James Cook University) on a partial scholarship from the Department of Education, designed to address a shortage of teachers. As part of the scholarship's terms, she spent a year at a teachers' training college in Brisbane before returning to Townsville to teach high school for at least two years. She taught German, geography, maths and English, saving her earnings to travel Europe for several years. Upon returning to Townsville, she completed her studies at night while teaching during the day, earning a degree in Geography in 1972 and a Master of Geography in 1975.

After working in various locations along Australia's east coast, including at the University of Newcastle, Sumner received a scholarship from the National Museum in Victoria to research German naturalist Amalie Dietrich in 1980. This research became the foundation of her PhD (1986) in the Department of History at The University of Queensland, under the supervision of John Moses.

As a geography professor, Sumner specialised in the social and environmental impacts of science and technology, as well as the built environment and history of tropical Queensland. She held a teaching and research position at the Queensland University of Technology before relocating to the United States when her engineer husband was offered a job at the California Institute of Technology. In the U.S., she held teaching and research positions in geography at California State University, Dominguez Hills, and Long Beach City College, where she worked for about twenty years. She was also involved with a local branch of the Society of Women Geographers and the California Geographical Society. Now retired, she continues to reside in the United States.
