Keith Lowe is one of our greatest historians of the Second World War and its aftermath. He joined us to share the story of Ben Ferencz, one of the Nuremberg prosecutors who made it his life's work to fight for peace. Search for Ben Ferencz and the Quest for World Peace: Keith Lowe on the Fear and the Freedom.

Keith's choice for our Hall of Fame is equally impressive. Someone who fought to try and change a nation's story of its war. But it is an uncomfortable nomination, because Yuasa Ken was a Japanese war criminal who performed horrendous human experiments during the war. Afterwards, however, he saw the light and dedicated the time he had left in the world to educate his country about its culpability.

This is a powerful and unsettling listen, but it is one which we all need to hear.

Joris Lechene joined us to understand the life and afterlife of the great John La Rose, one of the leading lights of Black British cultural life from the 1960s to the 1980s. And a few years ago, he was in the news again as London's Black Boy Lane was renamed in his honour. But the fallout was something to behold.

This is a gripping episode – the very essence of Trapped History. You can find it as Black Boy Lane: Joris Lechene on the Legacy of John La Rose.

And Joris' nomination for the Hall of Fame is equally fascinating. Because he doesn't nominate a person. He nominates a whole uprising, when the former slaves of Guadeloupe fought to the death against the French.

Anne Sebba breathed life into the story of the women of the French Resistance, in the brilliant The Women who Ran the Resistance: Anne Sebba on the Forgotten Heroines.

And in this Hall of Fame nomination, she does the same for the women of the death camps. Hilde Grunbaum's life is a truly emotional one as both she and dozens of other female musicians would make up the Women's Orchestra of Auschwitz. It was a lifeline in the midst of horror.

Sathnam Sanghera joined us to find out all about Cornelia Sorabji, the first woman to graduate from an Indian university, the first woman anywhere to get a law degree – from Oxford at that – and the first woman to represent the accused in a criminal case in a British-run court.

Her story is incredible – but even more astonishing is the tale Sathnam brings to the Hall of Fame: that of Dean Mahomed, an Indian surgeon, soldier and writer who settled in England. Which is where he established the country's first Indian restaurant and introduced the art of "shampooing" to Europe.

Prepare to be amazed! And then, head over to the main episode to hear all about The Indian Imperialist: Sathnam Sanghera on the Curious Cornelia Sorabji.

Sculptor Ian Wolter accompanied us on a cold and windy day to the mesmerising Memorial to Heroic Self-Sacrifice. The insights of a practising artist were priceless and so his choice for the Trapped History Hall of Fame is equally insightful.

Charles Jagger was a prize-winning young sculptor on the up when the First World War broke out. He quickly signed up and served in the trenches and at Gallipoli. He was awarded the Military Cross and was wounded three times.

On his return to civilian life, Charles was a changed man. And a changed artist too. Because while he would create many sculptures and statues which were not war-related, it is for his war memorials which he is remembered. They can be found in Belgium, France, Egypt and Australia but perhaps his most famous and heart-breaking one is London's Royal Artillery Memorial.

Ian is the perfect guide to the work and the emotions behind it. So when you've listened to this, head over to the main episode to hear Remembering the Ordinary: The Memorial to Heroic Self-Sacrifice.

The RAF pilot Trevor Edwards joined us to marvel at the life and times of Johnny Smythe. But here, he goes back to the very beginning and nominates Robbie Clarke, the very first Black RAF pilot.

Robbie's was a charmed life – a mechanic who would be one of the first Jamaicans to drive a car, he crossed the Atlantic to sign up in 1915. Joining the Royal Flying Corps, he gained his wings in April 1917, making him the first Allied Black wartime pilot.

It's an inspiring story so when you're done with this, head over to the main episode to hear about The Four Heroic Lives of Johnny Smythe.

Join us as Stephen Bourne unveils his Hall of fame nominee. You may remember, Stephen was our guest on our episode about the forgotten singer who was Adelaide Hall, and he doesn't stray far from the path here!

Mabel was born in Burton-upon-Trent, but she made her name in Paris and New York, where Cole Porter, Gertrude Stein and even Ol' Blue Eyes himself fell under her spell. Her story is eye-opening and a real counterpoint to Adelaide's.

When you've finished with this, turn to the main episode: Adelaide Hall – The Greatest Singer you've Never Heard Of.

At last, Trapped History's inaugural Hall of Fame nomination is here: Rosemary Brown's nominee from our very first episode.

You may remember that Rosemary joined us to find out all about the marvellous Nellie Bly, adventurer, entrepreneur, war reporter and one of the very first investigative journalists in history. And perhaps Nellie's greatest exploit was to play Jules Verne at his own game and travel around the world in (under) 80 days.

But Nellie wasn't the only person to do that. There was another woman travelling around the world . . . So tune in to hear the story of that other great tenacious traveller, Elizabeth Bisland.
