Children of Radium

‘A voyage into the heart of twentieth-century darkness [...] narrated with the twists and turns of a detective story’ Observer

Joe Dunthorne never met his great-grandfather Siegfried: an eccentric Jewish scientist who escaped Nazi Berlin in the 1930s and snuck back under cover of night to rescue the family heirlooms. Decades later, Siegfried wrote about his adventures in a memoir so long and rambling that almost no one ever managed to read it. Decades after that, his great-grandson Joe unearthed the dusty manuscript and got a nasty surprise. Because hidden on page 1,692 of the unreadable memoir was a shocking confession...

So begins a gripping journey into the twisting moral maze of the twentieth century – a journey to uncover a radioactive family secret.

Review

The best book I’ve read in the past year . . . Dunthorne brings distinction and finesse to every sentence, such as when he speaks of the old man’s depression, “washing dishes as if trying to drown them”. A masterpiece . . . It will be huge -- Andrew O'Hagan ― Financial Times

A slippery marvel. Warm and wry, heartfelt as well as undeniably comic, narrated with the twists and turns of a detective story . . . The book plays out as a tangled investigation of complicity, courage and cowardice [and] a quixotic voyage into the heart of 20th-century darkness ― Observer

Poignant, comic and searingly meaningful . . . [Joe Dunthorne] infuses this short, unconventional history with joy and pathos [and] shines a light on the absurdity of families, the unreliability of memoir and the general embarrassment of doing journalistic interviews, all of which make the gut punch of the book’s final quarter more profound. Remarkable ― The New York Times

Disturbing, wry, riveting, Children of Radium tells European history like never before ― Irish Times, 'Recommended Summer Reading 2025'

A nimble, questioning, entertaining book that nevertheless costs its subjects nothing in dignity . . . Dunthorne follows his material further than he might have done, taking the journey in many unexpected directions, and the book benefits from it. His account is also funnier than it has any right to be, since he is a wry guide . . . He maintains a personal touch while broadening out to tell a riveting, tentacular story ― Times Literary Supplement

Children of Radium is more than a memoir. It’s a detective thriller set in Berlin, Ankara and New York, as Dunthorne tries to track down the truth about his great-grandfather after nearly a century of distortions. It’s a book about what happens when a “comforting fantasy”, passed down through generations, is shattered by reality. It’s a lesson in history, chemistry and genocide studies, from radioactive toothpaste to chemical warfare. It is also, I should stress given the grimness of the subject matter, a funny, heart-warming and engaging page-turner… You don’t need a personal stake in this period of history to be moved, horrified and entertained by Dunthorne’s story, which is full of bizarre juxtapositions too strange to be fiction ― New Statesman

Narrated with the twists and turns of a detective story, Children of Radium is a family memoir that records Joe Dunthorne’s discovery of just how little he knew of his German Jewish heritage, and his grandmother’s childhood escape from the Nazis . . . As revelations and ambiguities mount, the book plays out as a tangled investigation of complicity, courage and cowardice, oscillating between potential indictment and mitigation ― Observer, 'Books of the Year 2025'

Enigmatic, self-deprecating, enjoyable . . . [Dunthorne] brings a novelist's eye for detail to Children of Radium ― Sunday Times

Spry, self-aware, irresistible . . . Dunthorne carefully fillets his vast material for the most vivid details . . . This is a valuable account which seeks neither to praise [its protagonist] nor to bury him -- John Self ― Financial Times

[An] excellent family memoir [and] a triumph of stylish prose . . . Dunthorne digs down through layers of memory and myth to uncover an unsettling story, tackling dark subject matter with moral precision and a surprisingly keen sense of humour . . . Children of Radium is a powerful exploration of the struggle to separate truth from the stories we want to believe. Dunthorne interrogates not just the omissions and self-deceptions in his great-grandfather's memoir, but also his own complicated motivations for revisiting his familial past ― Irish Times
