Kirsty Young's castaway is the educationalist Sir Ken Robinson.

Creativity - how to nurture it, develop it and marshal its power - is his preoccupation. He believes that too many people have no sense of their true talents and passions, and his internationally renowned talks to teachers, business and government leaders argue that - contrary to popular myth - creativity and innovation can be developed in a deliberate and systematic way. What we need, he thinks, is a learning revolution.

His own erudition began in a crowded house on Merseyside in the fifties, full of visitors, noise and laughter. His front door was just a hundred yards from Everton football club, but his boyhood dreams of playing for The Blues ended when he contracted polio.

The first of his six siblings to pass the 11-plus and win a scholarship to one of Liverpool's best schools, his education would fundamentally shape the rest of his life. He says "If a teacher hadn't seen something in me that I hadn't seen in myself, my life might have gone in a very different direction."

Professor Tanya Byron, clinical psychologist and TV presenter, is interviewed by Kirsty Young for Desert Island Discs.

Tanya has spent the last twenty years in clinical practice, helping children, young people and families deal with some of the most difficult parts of life - depression, anxiety, aggression, self harming and drug addiction.

She came to public prominence through her television work, books and advice columns and it would seem that she had the perfect background to cope with life in the spotlight - her father was a successful tv and theatre director and her mother worked variously as a nursing sister and a model.

A highly dramatic family tragedy ignited her interest in what spurs people to behave the way that they do.

She says of her work "I do have a particular desire to enable young people, on the cusp of what could be the most extraordinary life, to live ... and live well."

Kirsty Young's castaway this week is the former barrister and member of The House of Lords, Jeremy Hutchinson.

His life spans eleven decades of British history and he has spent much of it at the very centre of the action. Born during the First World War, he was brought up in the company of some of the greatest artists and writers of the day.

In World War II, he escaped his bombed-out ship clinging to a life raft with Lord Mountbatten.

At the Bar he played a central role in many of the seismic trials of the day - among them defending the novel Lady Chatterley's Lover against obscenity charges and Christine Keeler in the Profumo Affair trial. His brilliance in cross-examination inspired John Mortimer's creation of the character Rumpole of The Bailey.

He enjoyed two long marriages - his first to the actress Peggy Ashcroft, his second, for 40 years, to June Osborn, and he spent 23 years as an active member of The House of Lords.

He says, "I had the luck to live when the world of the Establishment was being dismantled. The whole of one's career was to do with what was going on in society."

Kirsty Young's castaway is the naturalist, Chris Packham.

TV presenter, filmmaker, writer, photographer, every bit of his work revolves around wildlife. If he's not busy telling us why we should love midges he's enthusing about the hearing capacity of a barn owl. His passion for animals is clear, what they think of him remains a little more uncertain; he's been attacked by a baboon, charged by lions and bitten by a puff adder.

His obsession with the natural world began early when a predictable boyhood fascination for tadpoles and ladybirds grew to encompass mosquito larvae, lizards, snakes and bats. As a teenager he collected badger droppings by day and pogoed with electric blue hair at Clash gigs by night.

These days he distinguishes himself by his impressive knowledge of his subject and his outspoken views on everything from countryside culls to the problems with cat owners.

He says, "I'll never rest until I've tried to do my own small bit in terms of changing the environment so it's a better place. I won't do it for my grandchildren because I won't have any and I won't do it for yours. I'll do it because it's the right thing to do."

Kirsty Young's castaway this week is businesswoman Carolyn McCall.

Currently Chief Executive of easyJet, she's one of only three women in Britain in charge of a FTSE 100 company. Prior to that she ran the Guardian Media Group.

An only child, she was brought up in Bangalore and Singapore. She spent a short time as a teacher in a comprehensive school and has also brought her wisdom to the boardroom table at Lloyds Bank, Tesco and New Look.

In amongst the corporate strategizing she also managed to have three children in three years.

She says, "I think it's mad not to have self-doubt ... but I think it's really dangerous when that self-doubt becomes total insecurity or lack of confidence or lack of momentum, or lack of belief in yourself."

Kirsty Young interviews the comedian Lee Mack.

He writes and stars in the BBC One hit show "Not Going Out". His stand-up tours do great business and his lightening sharp comedy reflexes are also put to good use on a number of prime-time panel shows.

His first ever performance was doing impressions for his school mates, but it took him more than ten years to pluck up the courage to step on stage. Leaving school with two O'levels and a cheeky grin, he had a stint as Red Rum's stable boy and a bash at being a professional darts player.

He says of his comedy career "I'm the kind of person that, if I don't think it's hard work, I worry that it's not worthwhile. I have to feel as if I've struggled a bit."

Kirsty Young's castaway this week is the novelist and critic, Zadie Smith.

First published at just twenty four her debut novel "White Teeth" garnered huge attention and praise. As a result she suffered the unnerving experience of doing her literary growing up in public.

Yet in spite of the scrutiny she blossomed. In the 13 years since, her novels, essays and short stories have brought numerous literary prizes and critical praise. Born to a Jamaican mother and a British father she was brought up in Willesden, North London where many of her characters live. She began writing at the age of 5 and was a voracious reader - devouring the greats of literature. Now she divides her time between Willesden and New York where she teaches creative writing.

She describes herself as "an English novelist enslaved to an ancient tradition" and yet her chosen areas of exploration could not be more of the moment.

She says, "I'm really interested in what memory feels like ... we only have snapshots of the past ..." she continues to declare that writing isn't about "being experimental, it's about finding something true."

Producer: Cathy Drysdale.

The psychologist Daniel Kahneman, who won the 2002 Nobel Prize for Economics, is interviewed by Kirsty Young for Desert Island Discs.

Widely acknowledged as one of the world's most influential living psychologists, his many years of study have centred on how and why we make the decisions we do.

As a child, he lived in Nazi occupied France and he says that, from a young age, he already had a pretty good idea that he wanted to be an academic.

He says "My mother had a big influence ... in fact I credit her with the fact that I became a psychologist ... because she got me interested in people and listening to gossip. I've been fascinated by gossip ever since."

Producer: Cathy Drysdale.

Kirsty Young's castaway is BAFTA award-winning production designer, Eve Stewart.

Her big screen credits include Les Miserables, The King's Speech and Vera Drake and for TV The Hour, Upstairs Downstairs and Call The Midwife. Responsible for locations, scenery and all the props she is renowned for creating entirely convincing, cohesive worlds that capture a beguiling sense of time, place and spirit. Not even the requirement for nine tons of Scottish seaweed or noiseless rubber rosary beads will defeat her.

Her trademark is her relentless attention to detail and she slavishly trawls the archives for visual clues and references. It would seem that the bug bit her early - she says:

'When I was a little girl I used to have lots of doll's houses. Now I have lots of big ones and get to do it on a bigger scale.'

Producer: Cathy Drysdale.

Kirsty Young's castaway is Mary Robinson, former President of Ireland and ex-UN Commissioner for Human Rights.

Her professional life has been defined by public service at the very highest level and she appears the epitome of the cool-headed pragmatist. And yet she is also something of an enigma: a committed Catholic who fought hard to legalise contraception and divorce; an elected head of state with both a noble bearing and a common touch.

As a lawyer she lead from the front championing controversial causes at home in Ireland and fiercely defending human rights at the UN. She also has a habit of making history - she was Ireland's first female president and the first Irish Head of state to meet Her Majesty the Queen at Buckingham Palace.

She says of her life and work "over the years I have given many talks and taken part in many discussions on leadership: women's leadership, political leadership, business leadership, grass roots leadership. But the element of leadership that really fascinates me is moral leadership."
