Just sorting out all the emails from after the Bloomsbury Festival event and found all these lovely compliments, which I cannot resist recording for posterity:
“a really enjoyable event and mixing in the young scientists worked really well. Well done to everyone involved!” Olivia
“I am so impressed with all the work that Diana, Sue and Ian put in as well as the actors and students. Brilliant!” Anita
“What a great event - I thought it was very moving seeing all those people standing listening and responding to the script. And if you’ve seen the David Attenborough documentary the PhD students are a shining beacon of hope that we might save humankind.” Ian.
“It really was a brilliant event, so well done to all! Jules and Sue struck just the right tone and it was so good having the students demonstrate the relevance tous today of Mr Nicholson's scientific endeavours. Great scripting, performances and direction, and flawless organisation and admin too (I know Diana and Sue put more time into this than you might guess). It was all impressive and generally wonderful.” Jo
“Ian, Sue and Jules - you were all excellent and clearly had worked very hard over many sessions to make the performance so polished, interesting, and amusing. You held the attention of that large audience and inclusion of the students was inspiring and they did their bit so well. Many thanks to you.” Sue
“What a fantastic event this afternoon! Everyone seemed to have a great time and I learnt a lot about William Nicholson and science. Huge congrats to Sue Bramall, the fabulous actor Jules Date and Ian Brown. Very well done.” Hans.
In case any the organisers of science or history events are looking for something a bit different – we’d love to do it again!
When I was asked to participate in the 2020 Bloomsbury Festival, with the Friends of St George’s Gardens, I was delighted to have an opportunity to spread the word about William Nicholson (1753-1815) and his interesting life.
I was especially happy when the FoSGG team proposed hiring an actor to play Mr Nicholson, and had great fun writing the script … up to the point when Nicholson’s interests turned to science.
It was easy to paint a vivid picture of life at sea with the East India Company, the theatrical shenanigans with Thomas Holcroft and the revolutionary and political events of that period.
But communicating about Nicholson’s experiments and the achievement of splitting water (with his colleague Anthony Carlisle) was a different matter.
I’ll confess to being a late-bloomer when it comes to any interest in science. My younger self would be astonished to learn that one day I might be interested about the history of science – nevermind reading and writing about it. I’m certainly not equipped to talk or even demonstrate it.
But just around the corner from St George’s Gardens is University College London, which was also involved with the Bloomsbury Festival, and which happens to have an electrochemistry outreach group. Several PhD students were keen to spread the word about the future of clean energy and the potential for hydrogen fuel cells – a technology which can trace its history in a direct line to Nicholson & Carlisle’s experiment in May 1800 in the house in Soho Square. (See this guest blog from Alice Llewellyn- How the discovery of electrolysis has changed the future’s energy landscape).
The UCL team comprised Alice Llewellyn, Harry Michael, Keenan Smith and Zahra Rana as presenters, and Katrina Mazloomian as videographer. They brought the science to life in a wonderfully engaging way.
This extract from ‘In Conversation with Mr Nicholson’ is now on the Nicholson’s Journal YouTube account and shows Mr Nicholson (played by Julian Date) talking to the PhD students as they:
This is followed by a Q&A session recorded from the online event. With questions including:
Thankfully our team of experts from UCL answered these questions most interestingly, and in plain English as you can see on the second of two videos from the Bloomsbury Festival.

When William Nicholson launched his Journal of Natural Philosophy, Chemistry and the Arts in 1979, part of his motivation was to speed up the transfer of scientific knowledge.
If he lived today, he would surely have embraced social media for that purpose - never lowering himself to insults or trolling!
Now he has added a Nicholson’s Journal YouTube account to his media channels, and we are able to share excerpts from ‘In Conversation with Mr Nicholson’ a performance for the Bloomsbury Festival 2020 which took place in the open air of St George’s Gardens, London where Nicholson is buried.
Directed and introduced by Ian Brown, episode one is the historical part where his biographer Sue Durrell interviews Nicholson who has returned from his grave in the gardens to talk about his life in the second half of the eighteenth century.
Nicholson is brought to life most ably by actor Julian Date, who reminisces about his life at the crossroads of Georgian arts, literature, science, and commerce, and discusses the importance of his discovery in splitting water using Volta’s battery, alongside his friend Dr. Carlisle.
The short three excerpts in this video cover:
• Working for Josiah Wedgwood in Amsterdam and at the General Chamber of Manufacturers
• Nicholson’s motivation for launching his Journal of Natural Philosophy, Chemistry and The Arts; and
• Remembering Humphry Davy and the Royal Institution and recalling the experiment with Anthony Carlisle where they split water into hydrogen and oxygen in May 1800.
This is the first of two videos from this event. Part two shows demonstrations of the experiment and discusses its implications in the quest for clean energy.
Julian Date is represented by Hilary Gagan Associates.
London is now in Tier 2 lockdown, which means that households in areas under high alert (Tier 2) can only mix with others outdoors, in groups of six or fewer.
It seems that Lady Luck has smiled on St George's Garden's once again, and as our event is an 'outdoor talk' with plenty of space for social distancing, then it still has the green light to proceed.
Ticketholders must wear a mask, stay in their bubble, avoid mingling and keep their distance from the performers.
A short history of the ups and downs of organising a live event for the Bloomsbury Festival during the coronavirus
On 17 March 2020, just a few days before our world turned upside down due to the coronavirus, I received an email from Diana at the Friends of St George’s Gardens (where Nicholson is buried):
“This is just a long shot. But how would you like to do a walk round St George’s Gardens and talk about William Nicholson in late October, as part of the Bloomsbury Festival? We did this in 2018 for Zachary Macaulay with two actors in costume – Zachary and his wife. … “
A few days later on 23 March, the nationwide lockdown was announced by the government. The prospect of 12 weeks at home provided the perfect opportunity to write up a script, and with everything looking so bleak, this was something exciting to look forward to.
At that time, although all summer events were being cancelled, we all thought that life would be back to normal after a few months and October was far enough ahead to be safe. How incredibly naïve!
By the end of April, we’d all embraced the powers of Zoom and a meeting with the Bloomsbury Festival team, led by Rosemary Richards, explained that they were going ahead with various contingency plans, and we should plan an online version as a backup.
I was also interested to see that UCL were participating in the festival – for I knew they had a history of science faculty. As I had started writing the script and reached the scientific bits, I was wondering how we could get the discovery of electrolysis across in an interesting and engaging way – as this was distinctlynot my area of expertise.
Having seen that the festival team had been involved with the science festival GravityFest, I asked if they might have any useful contacts at UCL. Fortunately on they wrote to say “UCell are happy to help/collaborate with you in giving a talk at the Bloomsbury festival” and Alice, Harry and Keenan agreed to comealong and recreate the water-splitting experiment from May 1800 and then demonstrate how electrolysis plays a role in clean energy production with their hydrogen fuel cell.
In May Diana emailed to mention “another committee member, Ian Brown, who is a theatre director and will have good ideas about how to make the most of a story.” Looking him up online to find he had run the highly regarded West Yorkshire Playhouse in Leeds for a decade, I didn’t know whetherto be delighted or petrified. The sum total of my dramatic experiences to date comprised playing Mary in a nativity play at infant school and a mime on a student trip to Santander a few decades ago – neither role having had any script – what had I let myself in for?
Thankfully, Ian turned out to be delightful and thoroughly put me at ease. He suggested the performance should take the form of an interview with Nicholson’s ghost (great idea!) and was also very pragmatic about the format of the online version when my multi-media ambitions ran away with themselves. Ian also took on the role of finding an actor, when it turned out that my friend was in a high-risk group and was shielding could be confined indefinitely (as it seemed at the time).
Details of the event had to be finalised for the programme by the end of May, and so it was agreed to perform live on the first Saturday 17th and the online event was scheduled for Tuesday 20th October. The title of the talk was agreed as “In conversation with Mr Nicholson” referring to the conversazione evenings which were hosted by Georgians.
The running order started with me interviewing the ghost of Nicholson about his life up to the point of the experiment in 1800 – then we would introduce the UCell team and Nicholson would take up the baton and ask them about their experiments and the future usefulness of his work. I was thrilled that we would be able to show how relevant his work had been to the future of clean energy, and in a way that would be much more visually interesting for an audience.
However, this was not without a few challenges of its own, as the UCell team had to get approval from the university for their participation and use of the fuel cell stack (a very valuable piece of kit, the size of a large supermarket trolley). And while we could record the interview on zoom at any time for use in the online version, the only chance to video the experiments would be on the 17th October (Covid-19 permitting).
We all pressed on in good faith, and I booked the last week of May off work to get the script finalised and over to Ian.
On 18 June, the festival team emailed to say “As you know, we are working with the current, and ever-changing, government advice regarding Covid-19 and social distancing, and of course the safety of our performers and festival goers is our absolute priority. With this in mind, we have come to the decision to cap the number of participants for your talk to 20 participants for the time being. As you can imagine, this is to protect the safety of the people attending, and yourself. If nearer the time restrictions are relaxed, we will release more tickets.” Having scoped out the layout in the gardens the FoSGG team were later able to increase this to a maximum of 30.
At the beginning of July, Ian helped me to shape the script – adding more depth to the character of Nicholson and his family, explaining all the other characters, adding some gossip and eliminating non-sequiturs!
We still didn’t have an actor for Mr Nicholson. Hugh Jackman was of course isolating in Australia, so I spent an evening looking through actor directory websites – mercilessly judging men solely on their appearances.
Meanwhile, lockdown had not ended, and we were all still working at home. It was necessary to decide on whether to charge participants an entry fee, and in the end it was decided that it was “a bit more than a talk, with a scientific demo and a speaker in costume” so fees were set at £8 for the live event and £5 for the online event. The Bloomsbury Festival typically do a 50/50 split with paid ticketed events, and they have a “box office intern” and volunteer present to deal with last minute onsite tickets and to take payments. Soon, the contract was signed and Diana was looking into whether we should or could use microphones.
On 21 July, Ian emailed to say he had found a potential Mr Nicholson “I got an email from a local actor this morning - he’s a barrister as well as an actor. Going to meet him.” A week later Julian Date had joined the team – a family barrister by day, I was amazed that he would have the head space to learn so many lines as well as running court cases up to the performance, but apparently these use different parts of the brain.
August and September saw us all rehearsing on Zoom and fine tuning the script. It was quite enchanting to see Jules bringing Mr Nicholson to life after the character had been rattling around in my brain for so long.
The UCell team could show us some of their science online – with a mini hydrogen-powered car – but we will not get the full picture until the big day. They normally participate in many live events, (and should have been in Florida for one of our rehearsals), but we were the only live event that was still on their calendar for this year.
Finding a costume for Julian turned out to be another challenge as all the theatres were closed, and consequently so were all the costumiers. Eventually a service in Bristol was identified which provides costumes to the BBC and could send it by post, so Julian had to provide his vital statistics.
September ended, and despite a variety of lockdown measures and a recent new restriction of group sizes to a maximum of six people, the event was still not cancelled. It was outdoors and thanks to Sue Heiser of FoSGG and her work on the risk assessment, it will be possible to keep everyone at an appropriate distance.
Tickets were selling and by October the live event quickly sold out its 30 tickets. But we still hadn’t nailed down the details of the online event, and while we thought we would be able to record all the interview on Zoom and the experiments on video, we were not sure how this would all come together and then be broadcast. Fortunately, Rosemary Richards called in Hannah a digital producer and Mirabel who is also at UCL and doing science outreach. There was a debate about the comparative merits of YouTube and Zoom, but the latter has the added advantage of participation and so we can have a Q&A at the end.
This put us on track and reassured us that someone who knew what they were doing would be pressing all the Zoom buttons on the day. I’ll be providing a live introduction before the interview and linking to the video, then managing the Q&A with someone from the UCL team who will handle the scientific questions.
On 7th October, we were still waiting to hear from UCell team whether they had approval from UCL to participate, and thankfully this came through and they can bring the hydrogen fuel cell stack. The costume has arrived in London, and everything is planned for next Saturday, the 17th October.
With coronavirus cases rising by the day again, and with les than a week to go, we are waiting with bated breath to hear whether there will be a “circuit-breaker” lockdown over half term or a local lockdown affecting London, and whether the live event will still go ahead.
It’s a long shot, but we re keeping our fingers crossed that the show will go on
It is very exciting to announce that William Nicholson (1753-1815) will be making an appearance at the 2020 Bloomsbury Festival alongside the UCL hydrogen fuel cell demonstrator!

A guest blog by Alice Llewellyn from UCell, the electrochemical outreach group at UCL
Shortly after the invention of the battery in the form of a voltaic pile by Alessandro Volta in 1800, William Nicholson (1753-1815) and Anthony Carlisle (1768-1840) discovered that water can be split into its constituent elements (hydrogen and oxygen) by using electrical energy.This phenomena is termed electrolysis and is the process of using electricity to produce a chemical change. Electrolysis was a critical discovery, which shook the scientific community at the time. It directly demonstrated a relationship between electricity and chemical elements. This fact helped scientific legends – Faraday, Arrhenius, Otswald and van’t Hoff develop the basics of physical chemistry as we know them.
Fast forward to today, and we are faced with one of the greatest challenges – climate change. This effect has accelerated the search for alternative fuels and energy storage devices fin order to decarbonise the energy sector. Burning fossil fuels (coal, oil and natural gas) for energy is the main cause of climate change as it produces carbon dioxide gas which leads to a greenhouse effect and the warming of our atmosphere.
A huge contender for alternative fuels is hydrogen. Hydrogen is the most abundant element in the universe. However, it does not typically exist as itself in nature and is most commonly bonded to other molecules, such as oxygen in water (H2O). This is where electrolysis plays a key role. Electrolysis can be used to extract hydrogen from the compound which can then go on to be used as a fuel. Moreover, if a renewable source of energy is used (for example wind or solar) to provide the electricity required to split the water, then there is no carbon footprint associated with this hydrogen production.
Hydrogen can then be used in fuel cells to produce electricity. Fuel cells are electrochemical energy devices, they convert chemical energy directly into electrical energy without any combustion. The way in which a fuel cell works is in fact the reverse process of electrolysis. In a fuel cell, hydrogen is split into its protons and electrons which then react with oxygen to produce water, electricity and a little bit of heat. As the only side product of this reaction is water, fuel cells are a very clean way to produce electricity.
Energy from renewable sources (wind, solar…) is intrinsically intermittent. Depending on the season or time of the day more or less energy is produced. To make sure the supply of energy is secure and stable, energy needs to be stored when an excess is produced and later fed back into the grid when needed. Water electrolysis offers grid stabilization. When a surplus of energy is available, e.g. during the day when the sun is shining, some of this energy is used to produce hydrogen. This hydrogen can then easily be stored in tanks. Whenever more energy is needed, e.g. when it is dark, hydrogen is taken from tanks and fuelcells are used to release the energy stored in the hydrogen.
Not only can hydrogen be used for grid stabilisation, but this can also be used to transform the transport sector, which contributes to around a quarter of the UK’s greenhouse gas emissions. Fuel cell vehicles are one of the solutions that have been adopted to tackle this problem and are classed as zero-emission vehicles (only water comes out of the exhaust).
In 2019, London adopted a fleet of hydrogen-powered double decker buses – a world first! As more people start to learn about this technology, more fuel cell vehicles can be spotted on our roads.
Without the discovery of electrolysis by Nicholson and Carlisle in 1800, it might not be possible to produce pure hydrogen for these applications in such an environmentally-friendly way, making the fight against climate change a more difficult task.
