Professor Dame Ottoline Leyser first realised plants are extraordinary and astonishing at school, when introduced to the round and wrinkled peas of Gregor Mendel. She is fascinated by plant genetics and as Regius Professor of Botany at the University of Cambridge her particular focus has been on a hormone called auxin which controls the growth of plants.

In 2020, she was appointed the chief executive of UK Research and Innovation whose mission is to work in partnership with research organisations, universities, businesses, charities and government to “push the frontiers of human knowledge and understanding" and deliver economic, social and cultural impact, with a budget of more than £8 billion each year.

Dame Ottoline is a fellow of the Royal Society and in 2017 she was appointed DBE for services to plant science, science in society and equality and diversity in science.

Her music choices include Mozart, Vaughan Williams and Debussy.

Walter Murch is a Hollywood legend. He’s won three Oscars for his sound and editing work on Apocalypse Now and The English Patient, and his credits include some of the most acclaimed and discussed films of the past half century – The Godfather trilogy, The Conversation, The Talented Mr Ripley.

He co-wrote the first movie George Lucas ever directed – the dystopian science fiction drama THX 1138. In 1985 he made his own directorial debut with Return to Oz – an unofficial sequel to The Wizard of Oz. As an editor and sound mixer - and the only person to win Academy Awards in both categories - he’s thought deeply about the craft of cinema and all its possibilities, ideas which he shared in his book In the Blink of an Eye.

Walter's musical choices include Wagner, Beethoven, Pergolesi and Chopin.

Kevin O’Hare is the director of the Royal Ballet and he probably finds it hard to remember a time when dance wasn’t part of his life. He started young, and joined the Royal Ballet School at the age of eleven. He went on to dance with Sadler’s Wells and Birmingham Royal Ballet, taking on roles such as Prince Siegfried in Swan Lake, Albrecht in Giselle and Romeo in Kenneth MacMillan's Romeo and Juliet.

He retired from the stage in 2000, at the age of 35, but before long he was back in the world of dance – this time behind the scenes. By 2009, he was Administrative Director of the Royal Ballet and oversaw their first tour to Cuba. Three years later he became overall director. He has since worked with a wide range of dancers, choreographers and composers, and helped steer the company through the Covid crisis.

Kevin's choices include music by Tchaikovsky, Thomas Ades, Rachmaninov and Anna Clyne.

The abstract painter Mali Morris is fascinated by colour and light, and has been exploring their possibilities in her work for more than 50 years.

She was born in Wales and studied at the University of Newcastle, where the Pop Art pioneer Richard Hamilton was one of her teachers. He brought her and fellow students news of New York which she says “seemed as far away to me as the moon”.

Mali herself taught at a number of art schools including Chelsea, the Slade School and the Royal College of Art. She was elected a Royal Academician in 2010, and last year, flags made from her work hung above Bond Street, not far from the Academy, in a riot of joyous colour.

She currently has a major exhibition at the Ikon Gallery in Birmingham.

Her musical choices include Bach, Beethoven, Vivaldi and some blues singing and whistling by Professor Longhair.

Abdulrazak Gurnah won the Nobel Prize for Literature in 2021, honouring a career in which he’s written ten novels, and many short stories and essays. He’s an Emeritus Professor at the University of Kent.

He was born in 1948 on the island of Zanzibar off the coast of East Africa, and first came to Britain as a refugee at the age of 18, in the aftermath of the Zanzibar Revolution.

In his Nobel Prize acceptance speech, he recalled how, even as a young schoolboy, he loved writing stories. He also reflected on how his move to England changed everything: "there", he said, "in my homesickness and amidst the anguish of a stranger’s life… I began to do a different kind of writing. There was a task to be done."

Abdulrazak's musical choices include Shostakovich, Mendelssohn, Miles Davis and the Malian kora player, Toumani Diabaté.

Chris Addison has built his career on laughter, as a stand-up comedian, a panellist on shows such as Mock the Week, and as an actor and director.

You perhaps saw him as Ollie, the hapless junior Whitehall adviser in The Thick of It, the political satire created by Armando Iannucci.

Chris has also performed in opera on the stage at Covent Garden – though in a speaking role. He is an opera fan, so his musical choices include Mozart and Rossini but also folk music by Eliza Carthy and a Swedish Christmas song.

Their choices range from music by Florence Price to performances by Nina Simone and soprano Jessye Norman.

Professor Fay Dowker is a theoretical physicist fascinated by space and time. She was obsessed with maths from a young age and went on to study at Cambridge University. There Professor Stephen Hawking became her mentor and a very close friend.

She is currently Professor of Theoretical Physics at Imperial College London where she researches “quantum gravity” – how the force of gravity works on the universe's tiniest particles.

Fay's musical choices include John Coltrane, Shostakovich, Bach and Handel.

Olivia Harrison is a prizewinning film producer and charity director. Last year she published Came the Lightening, a poignant collection of twenty poems dedicated to her late husband George Harrison of the Beatles. George died in November 2001, at the age of just 58, and Olivia describes her poems as ‘thoughts, feelings and words about life and death, but mostly love and our journey to the end’.

Olivia grew up in Los Angeles, and in her early 20s she joined A&M Records. She first met George in 1974 through her work, and went on to help run his Dark Horse record label. They married four years later. Olivia has protected George’s musical legacy since his death and continued the work of the Material World Foundation, the charity he founded 50 years ago. She also worked with Martin Scorsese to create an acclaimed, Emmy-winning documentary about George.

Olivia's musical choices include Bach, Mozart and Ravi Shankar, as well as recordings from Mexico and Bulgaria.

Peter Frankopan is a historian who likes to take on big ideas, sweeping across many centuries and national boundaries.

In his acclaimed book The Silk Roads: A New History of the World, published in 2015, he argued that the Persian empire gave rise to the West and he explored the importance of the trading routes that linked Arabia and Asia to Europe, and how they spread ideas, culture and religion. The book was a bestseller in the UK, China and India and even inspired a musical collaboration between singer Katie Melua and students at Oxford, where Peter is professor of global history. His follow-up, The New Silk Roads: the Future and Present of the World investigated how economic power is shifting eastwards.

More recently Peter has turned his attention to climate change. In The Earth Transformed he examined how it has dramatically shaped the development - and the demise - of civilisations across time.

Peter's musical choices include works by Tchaikovsky, Mozart and Edward Naylor.
