Composer Thea Musgrave celebrated her 90th birthday this year, an event marked by celebrations and concerts around the world, including the BBC Proms and the Edinburgh International Festival. She has published more than 150 compositions, including major orchestral works and numerous operas, and continues to write every day.

Thea was born in Edinburgh in May 1928, and still has sharp memories of hearing news of the Dunkirk evacuation in 1940. She learned the piano as a child, but had ambitions to become a doctor. She began medical studies at the University of Edinburgh, but after struggling with the sciences, she switched to the music department, which happened to be in an adjacent building. In the early 1950s, she spent four years studying composition with Nadia Boulanger in Paris before moving to London and establishing herself as a prominent member of British musical life.

In 1970 she became Guest Professor at the University of California, Santa Barbara. In 1971 she married the American opera conductor Peter Mark, and she has lived in the United States since 1972.

She was awarded a CBE in 2002, and earlier this year she was presented with The Queen's Medal for Music.

Tom Daley started diving aged seven and by the age of 14 was representing Great Britain at the 2008 Olympics in Beijing. He has won six British Championships, three European Championships and won the World Championships in 2009 and 2017.

Born in Plymouth in 1994, he’s the oldest son of Rob and Debbie Daley. He has two younger brothers. His success at a very young age led to widespread media attention, but as he became famous, he was bullied and had to change schools at the age of 15. His parents encouraged his sporting ambitions and he was always able to spot his father in the crowd at competitions because he’d be waving a huge union jack. In 2006 Rob was diagnosed with brain cancer and despite initially successful treatment, the cancer returned. He died in 2011, missing the London 2012 Olympics, where Tom won a bronze medal in the individual 10m platform event.

In 2013 Tom met Dustin Lance Black and they married in 2017. They recently became parents – through surrogacy – of a son called Robert. Tom is currently in training for the 2020 Tokyo Olympics.

Henry Marsh is a neurosurgeon, who pioneered a technique of operating on the brain while the patient is under local anaesthetic. The procedure is now standard practice. He is also an acclaimed writer.

He was born in 1950 in Oxford, where his father was an academic. His mother came to England as a political refugee from Nazi Germany in the late 1930s. Henry did not initially pursue a career in medicine: after dropping out of university, he found work as a hospital porter, and only then decided to train as a doctor.

He was appointed a consultant at St George’s Hospital, London, in 1987. He has spent his career in the NHS, and has also frequently worked abroad, in Ukraine, Nepal, Albania and elsewhere. He retired in 2015, but continues to teach one day a week and to work overseas to help less experienced surgeons.

In 2014, he published a memoir, Do No Harm, which was widely praised for its honesty about mistakes in the operating theatre.

Danielle de Niese is a soprano who has taken starring roles with leading opera companies around the world. She was born in Melbourne, Australia, to Sri Lankan parents, and at the age of eight she won a national TV talent show, singing a pop medley. When she was ten, her parents moved the family to Los Angeles, so that she could pursue her dream of becoming an opera singer. She also presented a TV programme, L.A. Kids, for which she won an Emmy award at the age of 16.

She made her professional operatic debut when she was 15 with the Los Angeles Opera, appeared briefly in Les Miserables on Broadway, and first performed with the Metropolitan Opera in New York at the age of 19, taking the role of Barbarina in a production of The Marriage of Figaro, directed by Jonathan Miller.

In 2005 she came to more widespread public attention with her performances as Cleopatra in Giulio Cesare at Glyndebourne, stepping into the role at the last minute when the original Cleopatra was unwell.

She first appeared at the Royal Opera House in London four years later, and her international stage career now ranges from baroque operas to new works. She has also presented a number of television programmes about music. She married Gus Christie, the grandson of Glyndebourne’s founder, in 2009.

Pam Ayres is a poet and broadcaster.

Pam was born in the Vale of the White Horse and retains her characteristic Berkshire burr. She is the youngest of six children, and grew up in the company of her four brothers and a sister in a small council house.

Although she was interested in writing from an early age, she failed her 11-plus exam and left school at 15 to join the Civil Service and later the Women's Royal Air Force, where she found opportunities to appear in amateur dramatics.

She began to perform her comic verse in local folk clubs in the early 1970s and her first break came when she secured a spot on BBC Radio Oxford. In 1975, she won the TV talent show Opportunity Knocks and by the following year she had given up her day job.

Pam has sold more than three million copies of her books, and has been called "the people's poet", thanks to her ability to write verse which resonates with a wide audience. Her best-loved poems include Oh, I Wish I'd Looked After Me Teeth, which was voted one of the UK's top ten comic verses in a BBC poll. Striking a very different note, her poem Woodland Burial has become a popular reading at funerals.

Marianne Elliott is the first woman to win two Tony awards for theatre direction: the first for War Horse and the second for The Curious Incident of the Dog in the Night Time. Both transferred to Broadway from the National Theatre, London, and have gone on to travel the world.

Marianne's parents, grandparents and great-grandparents all worked in the theatre. Her father, Michael Elliott, was a founding director of the Royal Exchange theatre in Manchester and her mother, Rosalind Knight, now in her 80s, has enjoyed a lifetime on the stage and is still working. Although Marianne read Drama at Hull University, it wasn't until she was in her late 20s that her career began, when she became assistant director at the Regents Park Open Air Theatre. She went on to follow in her father's footsteps, working at the Royal Exchange, before becoming Associate Director at the National Theatre in London. In 2017 she left to set up her own theatre company with producer Chris Harper. Their next show will be Stephen Sondheim's Company.

In addition to all her theatrical prizes, she has just been awarded the OBE for services to theatre in the 2018 Birthday Honours list. She is married to actor Nick Sidi and they have one daughter.

Baroness Newlove is the Victims' Commissioner for England and Wales. She became a campaigner after her husband, Garry Newlove, was murdered by several youths in 2007. Born in Salford in 1961 she grew up in a working class family. Having left school at sixteen she became a copy typist at a magistrate's court and later a committal court assistant. She met Garry when she was 20 and they married and had two daughters. In 1992, when he was just 32, Garry was diagnosed with stomach cancer. He survived and the couple went on to have a third daughter.

The family lived in an area of Warrington which was experiencing an increase in anti-social behaviour. In August 2007, Garry went outside to investigate a disturbance and was viciously attacked by some youths in front of his three daughters. Three days later, the decision was taken to switch off his life support. Three youths were subsequently found guilty of Garry's murder and in the wake of the family's experience, Helen set up an initiative called Newlove Warrington to provide support to the young people in the area.

She was given a peerage in 2010 and sits on the Conservative benches. She took up various roles in support of victims in the House of Lords, culminating in her appointment as Victims' Commissioner, a post she took up in 2013. She is currently in her second term and will be serving in the post until 2019.

Helen remarried in 2012.

Billie Jean King won 39 Grand Slams and a total of 20 Wimbledon titles and is regarded as one of the greatest tennis players of all time.

Born in California in 1943, she was the eldest daughter of Bill and Betty Moffitt. She discovered tennis at the age of ten: at 15 she won in her age bracket at the Southern California championships, and in 1961, she won the women’s doubles at Wimbledon with Karen Hantze, the youngest pair to achieve such a victory.

In 1968, when professional competitors were admitted to Grand Slam tournaments, she won Wimbledon for the third time and was paid just £750 while Rod Laver, the Men's champion, took home £2,000. So began her campaign for gender equality, which involved boycotting tournaments and setting up their own professional women’s circuit. In 1973, then aged 29, she beat the 55-year-old former tennis champion Bobby Riggs in a match which became known as 'The Battle of the Sexes': it remains the most-watched tennis match ever. That year the US Open awarded the same financial reward to men and women and in 2007 Wimbledon followed suit. Billie Jean also founded the Women’s Tennis Association and the Women’s Sports Foundation in the 1970s.

She married her husband, Larry, in 1965 but by the late 1960s, she had realised that she was gay. She was outed by a former lover who sued her for palimony in 1981, and although she won the case, she lost almost all her commercial endorsements. She has been with her partner, Ilana Kloss, for nearly 40 years and retired from singles matches in 1983 and doubles in 1990. She was awarded the Medal of Freedom by President Obama in 2009 and has continued to be an ambassador for her sport and for gender equality.

Philip Treacy is one of the most prolific and acclaimed hat designers working in the UK.

His work was very much in evidence at this year's Royal Wedding and at Royal Ascot. Meghan Markle wore one of his designs for her first official public engagement as the Duchess of Sussex. Other notable clients include Madonna, Tina Turner, Grace Jones, who has showcased his creations on and off stage, and Lady Gaga, for whom he made a black telephone hat.

Originally from Ahascragh, a small village in County Galway, Ireland, Philip learned to sew when he was six years old. He grew up opposite a church and he recalls how, as a young boy, he would go to all the weddings, uninvited, to look at the clothes and in particular the wedding dresses.

He went on to study fashion at the National College of Art and Design in Dublin, and then won a place on the MA fashion design course at the Royal College of Art in London, graduating in 1990 with first class honours. He enjoyed a meteoric rise to success when fashion stylist Isabella Blow saw his student hat collection. She introduced him to Karl Lagerfeld, who quickly invited him to design hats for Chanel Couture when he was still in his early twenties.

He has won the title of British Accessory Designer of the Year at the British Fashion Awards on five occasions, and was awarded an honorary OBE for services to the British fashion industry in 2007.

Guy Singh-Watson is an organic farmer and founder of Riverford, a major British supplier of organic vegetables through a box delivery scheme. Born in 1960 and the youngest of five children, his parents became tenant farmers in Devon in 1951. He describes himself as "a proper little farm boy", and spent his free time outside, clambering up trees, catching rabbits, rearing his own pig and helping on the farm.

Severely dyslexic, he disliked school, but thanks to an aptitude for performing well in exams, he won a place at Oxford University to read Agricultural and Forestry Science, graduating with a First. He briefly joined the family farm, but left to become a management consultant in London and then New York, returning to the farm in 1986. He started cultivating vegetables on three acres of land with a wheelbarrow and a borrowed tractor, and found his niche, moving from three to 18 to 50 acres quite rapidly.

Initially, Guy sold to supermarkets, but became convinced that there must be a better way of getting his produce to customers, and set up a veg box scheme in 1993. His company now delivers to around 50,000 homes a week and had a turnover of £56.7 million in 2017.
