Wies van Groningen started writing at the age of 60. Awareness of what she described as her ‘double blood’, which she learnt about through stories from her mother, brought her into the Moluccan community in the 1990s. In 1992 she visited her mother's family home in Oma. She published her first collection in 1995, featuring stories from her mother, Clara Hukom. Around 1998, Wies van Groningen switched from the Women's Library Utrecht, to
Museum Maluku, the Moluccan Historical Museum. There, she focused on recording
women's history, especially that of Moluccan women. In partnership with Christien Hetharia, she interviewed twenty Moluccan women, and published the interviews in
Holland ligt niet dicht bij de hemel (Holland is not close to heaven). The women interviewed were Susette Huwae, Coos Ayal, Jossy Keiluhu, Salomina (Mien) Sapuletej-Lawalata, Anna Bathseba de Fretes-Rehatta, Netty Batawangge-Tamonob, Naomi Lawalata-Usmany, Augustien Souisa,
Cisca Pattipilohy, Nona Matulessy, Annet Rahantoknam, Farida Pattisahusiwa, Colette Voorwinde, Fientje de Kock-Hully, Monica Akihary, Johanna Tomasowa-Tapilaha. At the Moluccan Historical Museum, she was active in collecting stories of Moluccan women and men in a project called
Meer dan een verhaal (More than a story). A public appeal was made inviting people to send in short stories about their Moluccan grandparents. Many stories were submitted and two collections of short stories were published,
Meer dan een verhaal and
Luister naar mijn verhaal. In 2010, van Groningen led the publication of
Pasar Cerita a new collection of stories with memories not only of Moluccans, but also of people from Indonesia and the Dutch East Indies. Wies van Groningen continued to write into her 90s. Her last book,
Vertellingen uit een koloniaal verleden, was published in 2021, a year before her death. In it she told the life story of her grandmother Louisa Hukom, who earned her living as a seamstress on the
Maluku Islands after being abandoned by her husband. Louisa Hukom's life had previously been described in the story ‘De goede slang’
(The good snake), by
Dutch-Indonesian writer
Maria Dermoût (1888–1962), whose family she had worked for. Wies van Groningen died in
IJsselstein on 30 December 2022. == Recognition ==
