She was born Louise Berta Mosson Smith in Melbourne, the daughter of Louis Smith, a medical practitioner and parliamentarian. Her brother (Sir) Harold Gengoult Smith was to become Lord Mayor of Melbourne in 1932.

She was a generous patron of the arts who organised private concerts of Baroque music, especially French. She was the major force in establishing the British Music Society of Victoria in 1921. In 1924 she helped Shaw Neilson publish his first major book of poetry and later donated £10,000 to help found the Melbourne Symphony Orchestra.
The couple moved to London 1927, then Paris in 1928. There they commenced what was to become a remarkable collection of printed music, scores and scholarly material from the 15th to 19th centuries.
She founded Éditions de l'Oiseau-Lyre in 1932, printing impeccable historical editions of the music of Lully, Couperin, Jacopo da Bologna and Purcell, then branching out into recorded performances which became their major focus. She also published works of modern Australian composers, notably Peggy Glanville-Hicks and Margaret Sutherland. She continued to run the publishing house until the year she died. She helped promote modern composers including Georges Auric, Benjamin Britten, Joseph Canteloube, Gustav Holst, Jacques Ibert, Vincent d'Indy, Charles Koechlin, Darius Milhaud, Albert Roussel and Henri Sauguet
She was appointed chevalier of the Legion of Honour in 1934 and promoted to officier in 1957.
James Dyer died in 1938. The following year she married 30-year-old British literary scholar Joseph Birch "Jeff" Hanson and moved to England, where he was studying at Balliol College, Oxford. They moved to Monaco in 1945 where she died, leaving her Australian assets valued at around £240,000 to the University of Melbourne. Her European assets were left to her husband.
Jeff Hanson remarried; when he died in 1971, his widow Margarita continued running Éditions de l'Oiseau-Lyre till 1996. In 1986 she left the collection of early European music and Classical imprints, manuscripts and scores to Melbourne University.
