The Manhattan Project, set up during the Second World War in 1942, was guided by fear that if the US and its allies didn’t make them first, Hitler’s Nazi scientists would.
A left-wing theoretical physicist not known for his leadership qualities or laboratory acumen, the American was an unconventional pick but proved a devastatingly effective one.
As blockbuster biopic Oppenheimer hits cinemas, Sky News looks at how the father of the atomic bomb still shapes the world decades after his creation was deployed.

Oppenheimer film ‘puts audience in bunker’
An unusual recruitment
Oppenheimer was appointed by General Leslie Groves, the project’s military leader, to head up Site Y – a secret weapons research facility at Los Alamos, New Mexico.

But there were, as Oppenheimer biographer Professor Ray Monk puts it, “all sorts of reasons” not to appoint him, notably perceived association with communist organisations that had made him a suspect of the FBI.
Born to a Jewish family in New York in 1906, his student years had seen him drawn to the left as Germany’s fascist regime saw friends and relatives oppressed and forced to flee.
During studies at Harvard, Cambridge, and Germany‘s Gottingen university in the 1920s, he was known for being a “disaster in the laboratory”. Of his time studying physics at Harvard, Oppenheimer himself said: “My feeling about myself was always one of extreme discontent.”

He may have been unconvincing in the lab, but found his calling as a university lecturer in California. His ability to explain complex science in a relatively straightforward and compelling way proved key to impressing Groves, who interviewed countless scientists before a chance meeting with Oppenheimer.
Crucially, he also recognised the need for urgency.
Prof Monk says: “Oppenheimer knew Heisenberg, one of the greatest scientists in the world, who he worked with at Gottingen, was leading the Nazi bomb project and was worried they would get one before the Allies.
“He was in no doubt at all – the duty of all scientists in the US, and the allied countries, was building a bomb first.”

Building the bomb
Los Alamos was one of three sites critical to the development of the atomic bomb.
The others were a factory in Hanford, Washington, where plutonium was made; and a hidden base in Oak Ridge, Tennessee, for enriching uranium.
The basis of atomic bomb is the process of nuclear fission – when the nucleus of an atom is split into two smaller nuclei, releasing a large amount of energy in the process.
This was discovered in 1938 by two German scientists, and Oppenheimer realised its destructive potential when word reached him in 1939.
The prospect of weaponising nuclear fission focused the minds of scientists across Europe, with plutonium and uranium identified as elements that could undergo the process.
With the process understood, the race was on to weaponise it.
Cynthia C Kelly is founder and president of the Atomic Heritage Foundation, dedicated to the preservation of the Manhattan Project and crucial to having the three sites gain national park status in the US.
“It was a first-of-a-kind effort across the board,” she says of the Manhattan Project, named after the New York City district where it was founded.
With the city that never sleeps deemed too busy for such a secretive initiative, the three laboratories were set up in isolated places far away from urban centres and the coast. They brought together geniuses from across America and overseas – including Britain and some who fled Nazi Germany – into one single-minded pursuit.

“It required creative minds from the machinists to the craftsmen – everything had to be perfect,” Kelly adds, with a “classic absent-minded professor” at the heart of it.
“They had to take this energy, which had been uncontrolled up to now, figure out how to control it, and package it tightly enough to fit in the bomb bay of an aeroplane that could transport it and drop it.
“They had little confidence in harnessing this technology in time for the end of the war.”

Becoming Death
But harness it they did – and the world would change forever.
The first atomic bomb test in New Mexico happened on 16 July 1945, after which Oppenheimer uttered a line that, along with his trademark fedora and pipe, has become quintessential to his public image.
“Now I am become Death, the destroyer of worlds,” he observed after the so-called Trinity Test, quoting a sacred Hindu text in a reminder of his acumen as a philosopher as well as a scientist.
A few weeks after, death followed on an unimaginable scale. On 6 August, a uranium-based bomb named Little Boy was detonated over Hiroshima; and another, Fat Man, was dropped on Nagasaki three days later.

Both cities were left unrecognisable, 200,000 people died, and Japan surrendered. Oppenheimer was shaken.
“Right up until the dropping of the bomb on Hiroshima, he had no moral qualms whatsoever,” says Prof Monk.
“Even when the Germans surrendered (on 7 May 1945), and it was obvious the Americans were still going to use the bomb against the Japanese, he had no qualms.
“But he thought one demonstration of the awesome power of this weapon was enough.”

A new world
Despite its undoubted role in ending the Second World War, which cost the lives of some 90 million people, Oppenheimer was changed by the atomic bomb, believing it made the prospect of future conflict “unendurable”.
“It has led us up those last few steps to the mountain pass; and beyond there is a different country,” he said in 1946, later signalling his opposition to his government’s plan to develop even bigger nuclear weapons.
Oppenheimer was ignored and held in deep suspicion, and his security clearance at the Atomic Energy Commission eventually rescinded. He died of lung cancer in 1967 with none of the power he once yielded.

Nuclear weapons have not been used again, but the threat lingers. America and Russia’s arsenals are far smaller than their Cold War peak, but they hold 90% of an estimated global stockpile of 13,000 weapons.
Ever since Oppenheimer witnessed the Trinity Test in the New Mexico desert, Cynthia C Kelly says there’s been “no way to put the genie back in the bottle”.

Two cities devastated beyond recognition have seemingly served as the ultimate deterrence.
“Oppenheimer was invited to say he regretted developing the atomic bomb many times, most prominently when he visited Japan, and his answer was always no,” says Prof Monk.
“It can be argued the fact the weapons have never been used again shows deterrence works.”

Will Russia use nuclear weapons?
Beyond deterrence, the Manhattan Project also unleashed an era of science and innovation still being felt today, including nuclear energy vital to weaning ourselves off greenhouse gases.
Actor Michael Madsen, who starred in Reservoir Dogs and Thelma & Louise, died from heart failure, his cardiologist has said.
The 67-year-old was found unresponsive in his home in Malibu, California, last Thursday and pronounced dead.
His doctor said heart disease and alcoholism will be listed as factors which contributed to the star’s death, reported NBC Los Angeles.
With no suspicious circumstances and the death listed as being from natural causes, the Los Angeles Sheriff’s Department considers the case closed.
In a career spanning more than 40 years, Madsen’s film credits include Free Willy, Donnie Brasco and Sin City.
He was also known for his collaborations with director Quentin Tarantino, including in Kill Bill: Vol. 2, The Hateful Eight and Once Upon A Time In Hollywood.
The Chicago-born actor also linked up with Tarantino when he played Mr Blonde in 1992’s Reservoir Dogs.

His sister, Oscar-nominated actress Virginia Madsen, paid tribute to her brother in a statement to Variety.
She wrote: “My brother Michael has left the stage.
“He was thunder and velvet. Mischief wrapped in tenderness. A poet disguised as an outlaw. A father, a son, a brother – etched in contradiction, tempered by love that left its mark.”
Madsen was preparing to release a new book called Tears For My Father: Outlaw Thoughts And Poems.
A statement by managers Susan Ferris and Smith, and publicist Liz Rodriguez, said the book by “one of Hollywood’s most iconic actors” was currently being edited.
Horse-drawn carriages, picturesque gardens and endless cups of tea are just some of the stereotypical tropes that have shaped America’s romanticised image of England before even stepping foot on the island.
Thanks to classical literature and a steady stream of period dramas, Lena Dunham was no exception.
“I had so many fantasies,” she tells Sky News about growing up slightly obsessed with British culture.
“I loved Jane Austen, I loved Charlotte Bronte, I love British film, I was one of those little Anglophile kids.”
The writer and director believed it would be that area of classically depicted England that would fill her time when she first moved to “jolly old London” as a teenager with her mother for a brief time.
Instead, her attention was taken by another, and possibly equally influential group of artists.
“There was a pop show about S Club 7 and all I did was just sit in the hotel and obsessively watch things relating to [the group],” she said.
“So, I didn’t go home with all this cultural British knowledge. I went home with a deep abiding love of S Club 7 and came back to school when everyone was obsessed with the Backstreet Boys and NSYNC.
“For me, I was literally like, ‘Guys, you got to hear this hot track right off the presses, it’s called Reach For The Stars’.”

It wasn’t until her 30s, when the actress moved again to the city, that reality took hold and she quickly learned the difference between the imagined London and the real city.
Some stereotypes hold true, like the universal love for Paddington. Still, TV tropes like renting a flat on a single income in the city does not necessarily mean you’ll be treated to lavish rooms and a picturesque garden.
She says it was social cues she found most challenging to adjust to, as well as the different dictionaries used when speaking, technically, the same language.
“You come to a new country and even though you speak the same language, you’re totally absent from those tools,” she says.
“And I found that really striking as an adult in my 30s, trying to make friends, trying to date. I found it confusing enough to be a person in my own city of origin, so this was extra confounding.”
Too Much, her new Netflixseries, is loosely inspired by her own London chapter and follows a workaholic New Yorker in her 30s who is sent across the Atlantic to work on a new project.
The 10-episode show is produced by Working Title – the company behind Bridget Jones, Notting Hill, About A Boy and Love Actually – and stars Hacks breakout actress Megan Stalter and The White Lotus actor Will Sharpe.

Dunham says she always wanted to write about her time in the UK, but it was a conversation with Irish actor Andrew Scott that got the ball rolling.
“Actually, he’s the reason that I came to know Meg as an actor because he loved her on Hacks and he loved her videos, and he said: ‘Have you watched this woman’s work? I feel like there’s a real connection between you two’, and I started watching because of him and built a show around her.”
In a full circle moment, Scott appears in the series briefly as an arrogantly odd man who crosses paths with Megan Stalter’s character Jessica.

The Ridley actor isn’t the only famous face joining the cast in a cameo role. Dunham put a call out to most of Hollywood, and luckily lots were on board.
To name just a few, guest stars include Jessica Alba, Stephen Fry, Adwoa Aboah, Kit Harington, Rita Wilson, Rita Ora, Richard E Grant, Emily Ratajkowski, Andrew Scott, Prasanna Puwanarajah and Jennifer Saunders.
“It was one of those situations where you just reach for the stars, literally, and then you can’t believe when they appear,” says Dunham.
“It was just a non-stop parade of people that I was fascinated by, wanted to be around, completely enamoured of.”

She adds: “I remember asking Naomi Watson, thinking, there’s absolutely no way that you’re going to want to come play this slightly demented woman. And she’s so playful and she’s so joyful and she just wanted to come and engage.
“Also, Jennifer Saunders has meant so much to me for so long, I had the AbFab box set as a kid, and I just think Patsy and Edina are the ultimate kind of messy women.
“She really showed me what comedy could be and… the space that women could occupy in comedy, and so having her come and join the show was really incredible.
“That was an episode that someone else was directing, Alicia McDonald, an amazing director, so I just got to sit and watch at the monitor like I was watching a movie, and it was very surreal for me.”
Former MasterChef host Gregg Wallace has vowed he will “not go quietly”, amid reports that he has been sacked by the BBC.
It comes after the TV hostfaced an investigation, commissioned by MasterChef’s production company Banijay UK, into alleged inappropriate behaviour while working for the BBC.
In November, the 60-year-old stepped back from presenting the cooking show after accusations that he made sexual comments towards staff and celebrity guests on a range of programmes over 17 years.

Broadcaster Kirsty Wark, author and actor Emma Kennedy, and presenter Kirstie Allsopp, were among the high-profile figures who made claims of inappropriate behaviour against Wallace.
In a statement, released ahead of the publication of the summary of a report into the claims, the 60-year-old said he had been “cleared of the most serious and sensational accusations” made against him.
However, he said the report, carried out by independent law firm Lewis Silkin, had found him “primarily guilty of inappropriate language between 2005 and 2018”.
Wallace’s statement, published on Instagram, came hours before the BBC News reported that 50 more people had made claims to the corporation against the presenter, including allegations he groped one MasterChef worker and pulled his trousers down in front of another.
In his statement, Wallace labelled BBC News’s claims as “uncorroborated tittle-tattle”.
Wallace wrote: “I have taken the decision to speak out ahead of the publication of the Silkin’s report – a decision I do not take lightly.
“But after 21 years of loyal service to the BBC, I cannot sit in silence while my reputation is further damaged to protect others.
“I have now been cleared by the Silkin’s report of the most serious and sensational accusations made against me.
“The most damaging claims (including from public figures which have not been upheld) were found to be baseless after a full and forensic six-month investigation.
“To be clear, the Silkin’s report exonerates me of all the serious allegations which made headlines last year and finds me primarily guilty of inappropriate language between 2005 and 2018.”

‘I was hired as the cheeky greengrocer – now that’s a problem’
Wallace said he recognised that “some of my humour and language” was at times “inappropriate” and, for that, he apologised “without reservation”.
“But I was never the caricature now being sold for clicks,” Wallace, who also referred to his recent diagnosis of autism, added.
“I was hired by the BBC and MasterChef as the cheeky greengrocer. A real person with warmth, character, rough edges, and all.
“For over two decades, that authenticity was part of the brand. Now, in a sanitised world, that same personality is seen as a problem.”

Wallace: Complaints from ‘middle-class women of a certain age’
Shortly after the allegations first emerged, Wallace recorded a video where he dismissed his accusers as “middle-class women of a certain age”.
His remarks were met with huge criticism – including from Downing Street, where a spokesperson for the prime minister described them as “completely inappropriate and misogynistic”.
Wallace responded by posting a follow-up clip where he apologised and said he “wasn’t in a good space” when he posted the comments.
In April, Wallace spoke to the Daily Mail, denying all accusations against him and saying he had contemplated suicide following the allegations.
Wallace’s lawyers have previously called allegations that he engages in behaviour of a sexually harassing nature “entirely false”.
A spokesperson for the BBC said: “Banijay UK instructed the law firm Lewis Silkin to run an investigation into allegations against Gregg Wallace. We are not going to comment until the investigation is complete and the findings are published.”
A Banijay spokesperson told Sky News: “We won’t be commenting until our report is published.” They have signalled the report will be published later this week or next.
Banijay previously said Wallace is “committed to fully co-operating” with the external review.
Alongside MasterChef, Wallace presented Inside The Factory for BBC Two from 2015 to 2023.
He also featured on various BBC shows over the years, including Saturday Kitchen, Eat Well For Less, Supermarket Secrets, Celebrity MasterChef and MasterChef: The Professionals, as well as being a Strictly Come Dancing contestant in 2014.
More recently, Wallace has been promoting his health and lifestyle website, offering one-to-one coaching from both himself and a team of experts, which includes nutritionists and doctors, and his wife Anna in the role of recipe curator.
