Unique Perspective, A Scientific London Guide and Speaker

The walking tours have arisen out of my own interests, enthusiasm and personality. I devised and researched them myself using resources including the British Library, Science Museum Library, Royal Institution, Post Office Archive and Zoological Society of London as well as local museums.

You can find heritage blue plaques on buildings for yourself here. But the locations of very many fascinating stories are not marked with plaques. Nor are the plaques, and associated guidebooks, particularly good at turning plain facts into stories.


I can give historical talks on subjects ranging from the telegraph to sewage treatment.

Most of my subjects are unsung heroes, but a few are villains. I had never heard of the vast majority of the improbable characters featured in my walks until I started researching. So don't expect to hear just about the well known names. That means there's still an unexplored world out there for you, full of pleasant surprises.


My London walks benefit from the random connections of geography. In one square, for example, I can talk about camouflage, medicine, tanks and computing. I feel that this makes them more varied and individual. The common thread, and also the result, is great stories of ingenuity, eccentricity and intelligence.

My Background

I trained at university as an engineer and have worked in responsible positions in different technological industries.

I have visited 51 countries, read widely, listened to BBC Radio 4 and attended lectures and talks at such places as the Royal Society, Royal Institution, Royal College of Surgeons, London Transport Museum, National Archives, Imperial College, Natural History Museum, Imperial War Museum, Gresham College, University College, King's College, Geological Society, various cemeteries and the Warburg Institute.

I am a volunteer at the Royal Institution (founded 1799) for which I have developed blogs and some walks. The RI is a delight for someone like me interested in the history of science.  I often get to handle things like Michael Faraday's shoe brushes or the world's oldest vacuum flask, and see written records left by some of the people I get to talk about on my walks. 

(I am proud to have this association with the Royal Institution but note that I do not speak for it, nor offer services on this web site on its behalf.)

I am also a guide for the London Canal Museum's summer towpath walks, and I have been engaged by Imperial College to provide tours to students and staff.


Through such activities I have attended training sessions by the Museum of London including Customer Care, Disability Awareness, Creating & Delivering Tours and Developing Family Friendly Tours.


I have researched my father's service in the Intelligence Corps in World War 2.

Sometimes I have been approached for my expertise by researchers working on film and TV productions.


My knowledge of science trivia also came in useful to the British Library which engaged me to contribute a few rounds of questions for their annual Talk Science Christmas Quiz in 2013 and 2015. In 2015 I contributed a guest blog post for British Library (Science) and London Knowledge Quarter, and I have been interviewed by Robert Elms on BBC Radio London.

I am a member of London Historians which brings together a mix of the knowledgeable and enthusiastic who want to talk about history (or anything else) in an informal and sociable atmosphere.

Also on Trip Advisor but here is a selection of other comments.


"Wonderfully researched quirky stuff amusingly delivered. Laurence engaged and enthused all of us. Five stars!" - HR 2016 (Time-Bombs, Trivia & Tibet)


"Pleasant occasional conversation, companionable silences, the gorgeous Canal Museum en route and glimpses of life on narrowboats - one with a bookshop and a ukelele player.  Laurence Scales is the perfect guide; this was leisurely, but informative and purposeful. We wound up with his home-made delicious Mango Cake in a park at the end; all round satisfaction." - SW 2016 (Regent's Canal 200)
