About Rose Summerfield
Lived 1864 – 1922 (aged 57). Rose Summerfield was an Australian trade unionist and suffragette.
Rose Anna Summerfield (18 April 1864 – 14 April 1922) also known as Rose Cadogan or Rose Hummer, was a radical feminist and labour activist. She was the mother of prominent Paraguayan ethnologist León Cadogan.
Early life Summerfield was born in Middleton Creek, Victoria. Her father was a Polish miner, and her mother Irish.
Political activities Summerfield's political activities began in 1886 when she joined the Australasian Secularist Association. Her interests included socialism, temperance, and women's rights. In the early 1890s, she began writing political pieces for the Democrat, the Liberator, the Northern People, the Hummer and its successor, the Worker (Sydney). By 1892 she was the most prominent organiser of working women in Sydney and in August of that year established a women's division of the Australian Workers' Union. Like many other radical writings at the time, it was also racist, portraying non-white people as a threat to the white working class.
By 1901, she was dissatisfied with New Australia. She moved with her family in 1908 to nearby Yataity and ran a store.
Later life and death Summerfield wanted to return to Australia from Paraguay, but her planned return in 1920 was called off when the couple lost their savings in a bank failure.
She died from cancer in Villa Rica, Paraguay, in 1922 and was buried in the Las Ovejas cemetery at New Australia.
Personal life In 1886, she married Henry Lewis Summerfield, and they moved to Waverley in Sydney. They had one son in 1887.
Henry died in 1890. Her second husband, John Cadogan, whom she married in 1897, was a cook and mine manager; they had four children together. In 1899, in Paraguay, she gave birth to León Cadogan, who made significant contributions to the study of Guaraní language and culture, and is considered one of the most important ethnologists of Paraguay.
