I recently heard the very sad news about the passing away of David Rennie, who lived for many years on Crescent Road. He was a big part of our community and a passionate (and tireless) campaigner for improvements to local transport and green initiatives.
I first met David in May 2015 when I saw a posting on the Alexandra Park Neighbours website for a French conversation group. At the time he was the only member and the group was almost mothballed, but generous as always, he agreed to meet me and help me learn the language. Every Saturday afternoon we would meet at Owens Delicatessens (at the time it had a café) and I was a beneficiary of his superior French knowledge. David was an excellent teacher and very quickly I became fluent.
How would I describe David? Retired and in his 80’s. He had a consistent uniform of matching coloured jumper and polo neck, soft peak hat and rucksack. A ready smile and a warm and welcoming character. Very quickly I got to know and like him. He told me that he had worked most of his life as an engineer at the Building Research Establishment in Watford, specialising in materials like plywood. Prior to this he had taught architecture and was a very skilled carpenter too.
One Saturday he said, “I can’t do French next week as I am running an event at a local fete”. I said, “Ok. Do you want me to help, and we can talk French as we do it?” And that is how I was first introduced to the Water Game - David’s unique aquatic horse racing game which he ran at fetes like Fins Feste and the Palace Gates Triangle street party for many years.
And David Rennie’s Water Game was a revelation. A superbly designed course full of pipes, water, chance mechanisms, stands and something called the water lift. I also saw something amazing. A child, who had become so captivated by the action of the Water Game, that they insisted on staying put and ignored their parent’s requests to move on. The child then spent the next two hours watching the Water Game, never missing a race!
This inspired me to make an award winning film about David and his Water Game, which was shown around the world and translated into many different languages. Below is a website that explains more and where you can watch the film.

The film came out at the time of the Covid-19 pandemic, and because of the isolation requirements, pensioners like David found their lives severely impacted in terms of shopping, cooking and socialising. David lived alone with his daughter residing in Southend-on-Sea.
And I remember how the neighbours and friends got together to buy shopping for him and later cook for him because David was told by the doctors that he was underweight! Thankfully David always loved apple pie, which helped fatten him up.
The years passed and one day I got a message from David asking if I could drive him to Southend so that he could be with his daughter. He was finding living alone hard now and he needed some help. Shortly thereafter his house was cleared of his possessions and put on the market and sold.
I was subsequently told by friends that he had gone into a nursing home where he seems to have had a pleasant life.
I have one final memory of David which I think speaks volumes about his positive outlook on life, his resourcefulness and his ingenuity. David played the flute and he used to tell me that he would meet up with friends for a musical evening – a bit of food, some tunes and some nice conversation. He told me that he was a big fan of the composer JS Bach and he said.
“I play lovely, challenging music, but very slowly because my skills are not good enough to play it at its proper speed. Yet it’s wonderful all the same”
David Rennie. Born 20th May, 1936: died 7th March 2026

Gudrun: I met D when we moved to the area some 30 years ago and he was giving a presentation to local residents and council officers about traffic calming methods that would cut congestion and pollution and reduce injuries and deaths to zero.
His knowledge and experience came from having trained as a civil engineer at Oxford university, and subsequently having worked as a civil servant in the Department of Transport, proposing traffic calming projects that were far ahead of the time.
Like myself, he was a member of the Green Party and shared the focus on social and environmental justice. We would became lifelong friends and got together regularly for Sunday breakfast or dinner with like-minded friends to discuss ideas for reducing car use in Crescent Road and Alexandra Park area.
At one stage, some 30 years ago, we measured the car traffic volume in Crescent Road during the rush hour and found that it exceeded 400 cars per hour.
The council has, to this day, not managed to reduce this volume of car traffic.
D proposed tree build-outs in the road to slow down speed-running and was disappointed when the council got it wrong and installed quite ineffective build outs, with trees too close to the pavement.
Towards the end of his residence in this area, he became a wheelchair user and experienced at first hand the painful and restricted access to overparked, broken and narrow pavements in this area. He was eager to demonstrate this, so I took some photos of him in his wheelchair [see below] and showed them to the council and relevant traffic calming groups. Unfortunately, this did not result in any substantial positive changes to this day.
D also spent time as a volunteer teaching simple science concepts to local primary school children. He taught them about planets using tennis balls, ping pong balls and footballs to demonstrate the size and distance of planets from each other.
He explained the concept of a pinhole camera, using a cardboard box with a small hole in it, shining a light on an object in front of the hole and seeing a silhouette of the object projected onto the inside of the wall of the box - upside down.
As a person, D was very quirky - he once calculated how many minutes per year it took to brush his teeth!
He kept an old Morris Minor outside Watford train stn bc there was no public transport, cycle parking or safe way to cycle the last stage of his journey to work at the Building Research Council. A government institution without any public transport links!
As soon as he retired, he got rid of the car.
D wrote several scientific books about light in buildings. Every summer, he would teach courses at his workplace for architects about these concepts.
D was regularly seen cycling in the Alexandra Park area, using his adapted bike for carrying shopping loads when he rode up to Muswell Hill to buy provisions. He had installed a wooden tray and large panniers on his bike to ensure that he could carry sufficient loads.
He would practice his German language skills with me - his words were flavoured by quaint expressions he had learned from old friends in Austria. Fun!
Thanks for saying this John. David was definitely someone with many sides. He contributed a good deal to the Palace Gates residents' association apart from contributing the water game to the annual fetes: he was interested in the formation of the food co-op set uip under the umbrella of the association, and he proposed the system of tree build-outs in Palace Gates Road which were intended to dissuade drivers from speeding along it. He brought some coloured diagrams to an association meeting to explain the theory behind it, which I think arose from experiments done in Sweden. Unfortunately he wasn't around when the council contractors came to install the features, apparently with conflicting sets of different plans for the work, and they did it in a way which is quite decorative, but completely missed the point of puting it in. I don't know what David actually thought about that.
I used to meet him quite often walking around the neighbourhood or in the park. On one occasion we discussed the dangers (particularly to the more senior amongst us) of tripping over the raised edges of flagstones in the pavement. He had a method for avoiding this which was that you should always walk with a long stride - which he could certainly do - so that your foot always descended from high enough up to avoid your toe catching anything on the ground: application of engineering principles to everyday life!
