Lucy Hawking is a British author and science educator whose books introduce children to space, scientific discovery and environmental questions. She is also the daughter of physicist Stephen Hawking and writer Jane Hawking, but her career includes journalism, adult fiction and educational projects of her own.
Her best-known work includes the George adventure series, developed with her father and other scientific contributors. More recently, she has explored climate and conservation through Princess Olivia Investigates. Understanding that writing career helps explain Lucy’s public life beyond her famous surname.
Who Is Lucy Hawking?
Lucy Hawking brings scientific subjects into stories for young readers. Her work connects characters, mysteries and adventures with questions about the world: How does the universe work? What happens to our oceans? How can children investigate changes around them?
She is a writer and communicator rather than a research physicist. That distinction matters because her contribution lies in making complex ideas approachable, working with specialists and giving children reasons to become curious about science. Her official biography describes a career built around that educational purpose.

These details draw on biographical reporting, university records and publisher information. Age is dated because it changes on her birthday.
Early Life
Lucy grew up mainly in Cambridge, where her father worked. Science was part of her family environment, alongside the everyday challenges of living with a parent who needed substantial physical support.
In an early interview, she recalled a childhood that included happiness and imaginative play, while also describing the pressures created by her father’s growing fame. Her recollections give a more personal picture of the Hawking household than the familiar image of a celebrated scientist surrounded by equations.
Education
Lucy studied French and Russian at Oxford. University College identifies her as a Modern Languages student who entered in 1989. Her studies also included time in Moscow, and she later studied international journalism at City University in London.
Her academic route was rooted in language and writing. That background fits the work she would later develop: choosing words carefully, shaping stories and explaining unfamiliar ideas to readers. She did not follow her father’s route into theoretical physics.
Lucy Hawking Nationality
Lucy Hawking is British and is frequently described as an English author. Her education and much of her professional life have been based in the United Kingdom, although her books and public talks reach international audiences.
Lucy Hawking Ethnicity
The authoritative biographies consulted for this article do not establish a specific self-described ethnicity. Her British nationality and English background should not be treated as substitutes for a verified statement about ethnic identity.
Lucy Hawking Age and Birthday
Lucy was born on 2 November 1970. She is 55 years old as of 26 September 2026 and turns 56 on 2 November 2026. Her publication history now spans more than two decades, beginning with adult fiction in the early 2000s and continuing through children’s books published in 2026.
Height and Appearance
Lucy’s height and body measurements are not confirmed in the reliable sources used here. Photographs accompany her official biography and university event reports, but they do not establish those measurements. Specific figures circulating without a traceable source should therefore be treated cautiously.
Parents and Family
Lucy is the middle child and only daughter of Stephen and Jane Hawking. Her father became internationally known for his work on cosmology and black holes. Her mother is a writer whose account of family life helped bring another perspective to the Hawking story.
The family’s later history included Stephen’s marriage to Elaine Mason in 1995. Elaine had been one of his nurses and became Lucy’s stepmother during that marriage, which ended in divorce in 2006.
| Family member | Relationship to Lucy |
|---|---|
| Stephen Hawking | Father |
| Jane Hawking | Mother |
| Robert Hawking | Older brother |
| Timothy Hawking | Younger brother |
| Elaine Mason | Former stepmother |
| William | Son |
Brothers Robert and Timothy
Lucy has two brothers: Robert, born in 1967, and Timothy Hawking, born in 1979. The three siblings appear together in accounts of Stephen and Jane’s family, although Lucy’s publishing career has given her a particularly visible public role.
Family connections also appear in the public record of Stephen’s remembrance. Westminster Abbey records that Lucy and Timothy laid flowers with Jane during the service at which his ashes were interred in June 2018.
Why Lucy Hawking Is Famous
Lucy is widely recognised through both her family connection and her children’s writing. The George books gave her an international audience, with her official biography reporting publication in more than 40 languages.
Her public profile also includes science events and educational work. In 2015, the University of New South Wales recognised both Lucy and Stephen for science communication, specifically acknowledging Lucy’s role in initiating the George series.
Journalism Career
Before becoming established as a children’s author, Lucy worked in journalism. Penguin describes her as a former journalist who wrote widely for British newspapers. Her career later shifted toward books and public talks about storytelling and science.
Journalism and educational writing share an important task: helping readers understand a subject without assuming specialist knowledge. In Lucy’s later books, that explanatory work sits alongside invented characters and plots, giving the information a narrative setting.
Early Novels
Lucy’s first novels were written for adults. The British Council lists Jaded, published in 2004, and Run for Your Life, published in 2005. The latter also appeared under the title The Accidental Marathon.
These titles are useful for understanding the order of her career. She was already publishing fiction before George’s Secret Key to the Universe appeared in 2007. Her move into children’s science writing brought together an existing interest in storytelling and a new educational audience.
Lucy Hawking’s Books
Her bibliography includes adult novels, children’s adventures, nonfiction and a picture book. The table below provides a reading guide to major titles; the six George novels appear separately in reading order.
| Book | Publication year | Format or focus |
|---|---|---|
| Jaded | 2004 | Adult fiction |
| Run for Your Life / The Accidental Marathon | 2005 | Adult fiction |
| Unlocking the Universe | 2020 | Science nonfiction with Stephen Hawking |
| Princess Olivia Investigates: The Wrong Weather | 2022 | Environmental science adventure |
| Princess Olivia Investigates: The Sea of Plastic | 2023 | Adventure involving oceans and plastic |
| You and the Universe | 2024 | Picture book credited to Stephen and Lucy Hawking |
| Princess Olivia Investigates: The Knights of Nature | 2026 | Environmental mystery and conservation |
Years refer to the editions or original publication records checked; paperback, audio and overseas editions can carry different dates. The titles also show how her writing has expanded from adult fiction into several forms of children’s publishing.
The George Series
The George stories combine imagined adventures with scientific explanations. George and his friend Annie encounter questions about space and the universe, allowing readers to follow characters while also meeting ideas that belong to real science.
| Reading order | Book | First publication year |
|---|---|---|
| 1 | George’s Secret Key to the Universe | 2007 |
| 2 | George’s Cosmic Treasure Hunt | 2009 |
| 3 | George and the Big Bang | 2011 |
| 4 | George and the Unbreakable Code | 2014 |
| 5 | George and the Blue Moon | 2016 |
| 6 | George and the Ship of Time | 2018 |
The first book was created by Lucy and Stephen with physicist Christophe Galfard. Authorship should be checked title by title: Penguin credits George and the Ship of Time to Lucy. The related nonfiction collection Unlocking the Universe is a separate type of book, rather than another George adventure novel.
Writing with Stephen Hawking
Lucy and Stephen brought different skills to their collaboration. Lucy has described creating the characters and plots while her father served as scientific adviser. Their partnership combined the demands of a readable story with the need to handle scientific ideas carefully.
UNSW’s account of their 2015 award makes their shared goal clear: reaching young audiences was central to the project. The books gave children a way to engage with questions often associated with advanced study, without requiring them to begin with equations or technical textbooks.
Princess Olivia Investigates
Princess Olivia Investigates moves the setting toward environmental questions. Illustrated by Zoe Persico, the series follows a young character who would rather investigate as a scientist than simply follow the expectations attached to being a princess.
The Wrong Weather appeared in 2022, followed by The Sea of Plastic in 2023. The Knights of Nature was published in the UK on 30 April 2026. In that third story, Olivia and her friends recognise connections between environmental problems and join forces with a group working to protect nature.
You and the Universe
You and the Universe was published in 2024, with Stephen and Lucy Hawking credited as authors and Xin Li as illustrator. The US publisher lists it for children aged four to eight.
The picture book draws on Stephen’s message about curiosity, humanity and looking after Earth. It offers a shorter, illustrated introduction to those themes than a chapter-book adventure. For families exploring Lucy’s bibliography, it represents a different reading format and age range from the George novels.
Science Education Projects
Lucy’s educational work extends beyond books sold in shops. She worked with Curved House Kids on the Principia Space Diary, a project connected with astronaut Tim Peake’s mission to the International Space Station.
The programme combined space learning with creative activities and literacy. Her official website also lists the Principia Mars Diary, which introduces children to real projects investigating human exploration of Mars. These resources place scientific questions inside activities that pupils can complete and discuss.
Awards and Recognition
Lucy’s recognition includes the 2008 Sapio Prize for science popularisation, the 2015 UNSW Medal for Science Communication and an honorary science doctorate from Queen Mary University of London in 2015.
An honorary doctorate recognises contribution and achievement; it does not mean she completed a research doctorate in physics. In her case, the recognition reflects the educational value of communicating science through writing and outreach.
Marriage and Divorce
Lucy married Alex Mackenzie Smith in 1998. A contemporary profile discusses their marriage, and published biographical accounts give 2004 as the year of their divorce.
Her current relationship status is not established by the sources checked for this article. Her documented marriage can be described without assuming that older reports explain her private life today.
Her Son William
Lucy has a son named William, born in 1997. She has spoken publicly about motherhood and about William being autistic. Those discussions form part of the background to her interest in autism awareness and support.
William is not the subject of the same public career as his mother. Available reporting supports those basic family details, but it does not justify assumptions about his present circumstances or daily life.
Autism and Disability Advocacy
Lucy’s official biography lists her involvement with the Autism Research Trust. It also records her work with the Guardian on The Party, a 2017 virtual-reality film centred on an autistic teenage girl.
That project shows how her storytelling has extended into another medium. Instead of approaching communication only through printed explanations, a film can place an audience inside a constructed social situation. In Lucy’s wider career, it sits alongside her work on making information and experiences more accessible.
Stephen Hawking Foundation
Lucy’s official biography identifies her as chairperson of the Stephen Hawking Foundation. Westminster Abbey describes the foundation’s purposes as supporting the continuation of Stephen’s scientific work and research into the universe and motor neurone disease.
The connection brings together two major parts of her public life: science communication and disability-related concerns. The foundation also provides an organisational setting for work associated with her father’s legacy, alongside the books published under the Hawking name.
Preserving Her Father Legacy
Stephen died on 14 March 2018. Lucy’s involvement in remembrance has included public family occasions as well as continued publishing. At the Westminster Abbey service on 15 June 2018, she participated in the laying of flowers when his ashes were interred.
Later books also keep his ideas available to younger audiences. Unlocking the Universe collects scientific material in a nonfiction format, while You and the Universe introduces themes from his public message through illustrations and a shorter text. These publications offer different routes into the questions that shaped his public work.
Lucy Hawking Net Worth
Lucy Hawking’s net worth is not established by a reliable public financial disclosure identified for this article. Online estimates should not be presented as verified figures simply because they appear on multiple biography websites.
Her publishing and speaking career is publicly documented. However, book sales, family associations and charitable roles do not reveal an individual’s assets, liabilities or personal income.
Lucy Hawking Today
As of September 2026, Lucy’s recent publishing work includes The Knights of Nature. Penguin’s current author material continues to describe her as a children’s writer and public speaker on science and stories.
Her newer environmental adventures broaden the subjects covered in her bibliography. Alongside the space-focused George books, they give readers a way to explore questions about the planet they already inhabit.
Lucy Hawking’s Wikipedia
Lucy Hawking has an English-language Wikipedia biography covering her education, writing, family and charitable work. It can provide a starting point for readers, particularly through its references.
For publication dates, author credits and new releases, publisher listings are more direct sources. University records and Lucy’s official website are also useful for checking education, awards and the projects associated with her name.
Lesser-Known Facts
One family connection extends to Lucy’s university: University College, Oxford, records that her father Stephen and grandfather Frank also studied there. Lucy followed a different subject, choosing Modern Languages.
Her bibliography also contains more variety than a list of space adventures suggests. Before writing for children she published adult novels, and her later output includes a nonfiction collection, classroom resources and an illustrated picture book.
