THE SMEATON LECTURE
The Smeaton Lecture is given annually at the Institution of Civil Engineers at One Great George Street, London. The topic is on a matter related to engineering history and heritage, or a reflective retrospective on a distinguished engineering career. Since 2015 it has been delivered by a member of the Smeatonian Society as a result of an agreement between the Society and the ICE. The speaker is nominated by the Chairman of ICE's Panel for Historical Engineering Works, ICE's Director of Engineering Knowledge and the President of the Smeatonian Society. This page provides links to the most recent lectures held in the ICE archives.
JOHN SMEATON, MECHANICAL ENGINEEER - ROTATING MACHINERY, HISTORY AND LEGACY
The 2024 ICE Smeaton Lecture was delivered on 16th July 2024 by Ric Parker, visiting professor in mechanical engineering at Imperial College London. He provided a retrospective of John Smeaton’s work – in particular, his achievements in the field of rotating machines.
It’s notable that virtually every piece of writing about the great man starts by calling him “John Smeaton, civil engineer”. Smeaton actually coined this term to describe himself. In the early 18th century, “engineer” was defined as “one who designs and constructs military engines or works”, so he was making a deliberate bid to distinguish his endeavours and those of his like-minded colleagues.
While his major civil works – including bridges, canals and lighthouses – are rightly celebrated, previous retrospectives have already covered these in some detail. This lecture, commemorating the 300th anniversary of Smeaton’s birth, focused on his contributions to rotating machines such as windmills, water wheels and steam engines.
With his scientific education (it was impossible to obtain a degree in anything like engineering until the late 19th century), Smeaton was a great experimentalist, deriving numerous rules and constants as design aids. His lift coefficient for a windmill sail, for instance, was used by the Wright brothers in 1900 when they were developing the world’s first aeroplane. Even today’s wind turbines, which are producing a growing proportion of the UK’s green energy, can be considered part of Smeaton’s remarkable legacy.
Parker worked for 37 years at the Rolls-Royce Group, where he was immersed in the engineering of rotating machines. The gas turbine, whether used for energy generation or vehicular propulsion, formed a key part of his career, but he has also been involved in many other interesting projects, including work to harness tidal power.

SUSTAINABLE DEVELOPMENT: FROM SMEATON TO THE 21st CENTURY
The 2023 Smeaton Lecture was given by First Class member Professor Peter Guthrie, professor of engineering for sustainable development at the University of Cambridge, on the topic of "Sustainable development: from Smeaton to the 21st century" on 11th December 2023 at the Institution of Civil Engineers and online..
The term ‘sustainable development’ entered the policy lexicon with the 1987 report Our Common Future, by the World Commission on Environment and Development. Historically, civil engineers have always held the future of their work and its wider societal impact as a central tenet of their profession, and this consideration has become even more important against today’s background of climate change.
The engineers that shaped the Industrial Revolution also faced unprecedented challenges. Among the most influential of these was John Smeaton (1724-92), who was responsible for a series of bridges, canals, harbours and lighthouses, beginning with Cornwall’s Eddystone lighthouse in 1759. Twelve years later, Smeaton and six fellow practitioners of the new profession of civil engineering formed the Smeatonian Society to discuss matters of common interest.
This lecture explored the basis on which Smeaton and his contemporaries made their decisions, and considered the very different and more complex environment in which today’s engineers operate. Sustainable development now demands the explicit consideration of the impact of schemes on the environment, society and the economy, as well as an assessment of the effects on climate change. Today’s civil engineers require a broad range of expertise, reflecting the holistic approach of engineers in the 18th and 19th centuries.
The lecture drew on the lessons from Smeaton’s era, as well as developments of the past 50 years, to propose what civil engineers must address as the global target of net-zero carbon emissions by 2050 approaches. Peter also reflected on the need for the engineering profession to show leadership in sustainable development and addressed the question of what it means to be a civil engineer.

WHO DESIGNED THE CLIFTON SUSPENSION BRIDGE
The 2022 lecture was held in person and virtually on 11th July 2022 at 17:30 - 19:00. Introduced by Ed McCann, President of the ICE (21/22) and presented by Honorary Smeatonian member Julia Elton, Engineering Historian and Past President of the Newcomen Society.
Every modern biographer of Isambard Kingdom Brunel has followed the line taken by his son that Thomas Telford, as adjudicator of the 1829 competition, turned down Brunel’s design in favour of his own. The story goes that he refused to countenance spans longer than that of his own Menai Bridge and therefore turned down Brunel’s design of 1000 feet in favour of his own design.
However, on examining the archives at the Bristol Record Office and Brunel Institute, it becomes clear that this account is entirely untrue, casting an unjustifiable slur on Telford’s reputation to promote the genius of I.K. Brunel.
This year’s lecture looked at the bridges preceding Clifton, putting it in context with contemporary developments. It examined Telford’s role and gave an overview of the many other entrants and their designs and consider the subsequent history of the bridge and its completion in 1864 by William Henry Barlow and Sir John Hawkshaw, comparing their design with Brunel’s unbuilt winning scheme.
The lecture tells the true story of Bristol’s iconic bridge and drew out lessons for civil engineers today as they design challenging projects and adapt to developments in technology and technical capabilities.

COAL-FIRED POWER GENERATION IN THE UK: THE BEGINNING AND THE END
The 2021 lecture was held virtually on 20th July 2021 at 18:00 - 19:00. Introduced by Rachel Skinner, President of the ICE (20/21) and presented by Smeatonian John Baxter, non- Executive Director on the Sellafield Ltd and Drax plc Boards
When the Romans invaded Britain they discovered extensive coal fields. By the 18th century coal was the main source of heat and power and in 1769 James Watt patented a steam engine utilising a separate steam condenser which revolutionised energy production. However it wasn’t until over a century later in 1882 that the world’s first coal-fired power station generating electricity for public use was opened at Holborn Viaduct, London.
From there coal production and electricity generation from coal grew exponentially. By 1920 almost 100% of electricity came from coal. With energy consumption growing at an enormous rate and Britain’s economy stabilised post WW2 a massive programme to build new coal fired power stations was started. Production stayed above 90% until the late 1950’s as nuclear began to supplement coal. In the late 1980’s the ‘dash for gas’ was enabled and renewables began to appear as potentially commercially viable. From there climate change and the focus on CO2 emissions rang the death knell for the use of coal.
The drive and determination of the UK’s power engineers shows as much ingenuity and invention as their Smeatonian forebears and other early engineers. Significant engineering and operational challenges were faced and overcome to provide the nation with continuous and inexpensive electricity from coal. Most people have no idea what is involved in getting electricity to the lightbulb in their house.
John Baxter plotted the journey of coal-fired electricity production in the UK and use the Drax powers station to illustrate the challenges and successes faced by power engineers. He also gave an insight into Biomass power generation, combined with Carbon Capture and Storage and the potential for a “negative emissions” power plant that could be the hub of a zero emissions industrial region.

THE BRITISH CONSULTING ENGINEERS WHO CREATED THE WORLD'S INFRASTRUCTURE
SMEATON AND WATT: UNLEASHING THE POWER THAT CHANGED THE WORLD
The 2020 Smeaton Lecture, presented by Hugh Ferguson. Hon. Treasure of the Smeatonian Society, covered the full history of British consulting engineers, from early beginnings through to the establishment of the profession in the 18th century, the Railway Age of the 1800s, their post-World War Two international boom and the recent commercialisation and consolidation of the industry.
Detailing a remarkable story, peppered with great successes and spectacular failures, the lecture also examined how these engineers created much of the global infrastructure used during the 19th century before doing so again, for the developing world, during the post-war years. This was followed by a panel discussion around what lessons have been learned from the past and how they could be used to shape the future of civil engineering.
The 18th century saw unprecedented advances in our ability to harness power. Much of this was down to James Watt whose invention of the separate condenser and other improvements to the Newcomen engine was the key that unlocked the full potential of the power of steam. Watt then mastered rotative power for factories, accelerating the industrial revolution. Smeaton had also made improvements to the Newcomen engine and he and Watt shared a mutual respect.
The 2019 Smeaton lecture, presented by Professor Gordon Masterton, explored this relationship with the help of some letters, not previously published or archived, and uses engineering hindsight to explore the factors influencing successful innovation – then and now.
THE BREADTH OF ENGINEERING: THE IMPACT OF METROS IN THE WORLD'S GREAT CITIES
THE HISTORY OF THE THAMES TUNNEL CONSTRUCTION
Engineering is a much broader discipline than many of us were taught, or have understood. The problem with the engineering profession is that we have not recognised that many of the skills required for success have nothing to do with maths or physics.
Tony Ridley, Past President of ICE, will illustrate the breadth of engineering through his experience as Managing Director and Chairman for some of the world's great metros. He drew upon lessons learned from a career at the highest level of civil engineering, taken from his recently published book "Engineering in Perspective – Lessons for a Successful Career".
His colleague Richard Anderson, Managing Director of the Railway Technology Strategy Centre (RTSC) at Imperial College London, described the history of the RTSC, drawing on examples from benchmarking undertaken for metro systems worldwide to demonstrate the growth and the beneficial impact of metros serving diverse communities.
The 2018 Smeaton Lecture, in the spirit of ICE200, brought out lessons learned from engineering history that are essential for engineers of the 21st century.
The 2017 Smeaton Lecture presented by Professor Lord Robert Mair, described Marc Brunel's pioneering idea of a moveable shield for tunnelling through soft ground, and the heroic construction of the Thames Tunnel, the first civil engineering project on which his son I K Brunel worked. The lecture also described the latest tunnelling technology applied in the Crossrail project with 21 kilometres of sub-surface twin bore tunnels and 8 new sub-surface stations, focusing on the importance of geology and recent innovations.
Important questions were discussed, such as whether buildings above will be damaged by subsidence, how they can be protected and how existing underground infrastructure might be affected by new tunnel construction. Recent research advances and innovations were described, including novel techniques for monitoring construction and whole-life performance using fibre optic technology and wireless sensor networks.
LIVERPOOL TO MANCHESTER IN 1830: THE DESIGN AND CONSTRUCTION OF THE WORLD'S FIRST INTERCITY RAILWAY
WORLD WAR II ENGINEERS - ENABLERS OF VICTORY
The 2016 Smeaton Lecture, Presented by Mike Chrimes, looked at the design and construction of the Liverpool to Manchester railway.
Opened on 15-16 September 1830, the Liverpool to Manchester Railway is the first main-line and intercity railway in the world. As such it was a prototype project, and remains of global interest, most famously for the establishment of steam locomotive traction as a prime mover, paving the way for a transport revolution that transformed the world over the next 50 years. The Railway was a showcase for British engineering establishing a demand for British engineering expertise all over the world.
The lecture described the planning, procurement, design, management and construction of this pioneering engineering work and its initial operation. It considered the project in the context of the state of civil engineering in the 1820s and its significance today.
The line involved many major engineering works: tunnels and deep cuttings through sandstone, long crossings of deep bogs, inclines considered too steep for locomotive working, and majestic bridges and viaducts. The total quantity of excavation for the railway was about 3m. cubic yards.
The station at Liverpool Road, Manchester is the oldest passenger station in the world and sufficient of its 63 bridges and infrastructure survive to justify its inscription as an ASCE International Civil Engineering landmark in 2016.
During 2015 the nation commemorated many important historic milestones including the 75th anniversary of the Battle of Britain and the 70th anniversary of the end of the Second World War. The 2015 Smeaton Lecture, Presented by Gwilym Roberts, looked at each of the six key WW2 campaigns and battles that the allies had to win to achieve eventual victory, where superior technology reinforced the valour of the troops engaged in the battles.
While thousands of engineers and other technologists conceived, designed and produced the novel weapons, machines and structures that enabled victory to be achieved, many more applied their expertise in the fighting services - while others, mostly civilians and often against incredible odds, produced the myriad artefacts needed for victory or operated, maintained, augmented and repaired the national infrastructure so that essential services could continue to operate even in the direst circumstances.
The lecture summarised these achievements as well as highlighting the scale of the projects and the tempo at which they were completed. After brief accounts of the actions that led to the award of honours and gallantry medals to some of those ICE members who also achieved distinction in the profession after the war, the lecture concluded with suggestions as to the lessons that today's engineers - and statesmen - might learn from the achievements of their forebears.
THE NEW RIVER: EDMUND COLTHURST AND ITS DESIGN, 1600 – 1607
The New River is a contour aqueduct that first delivered fresh water from springs near Hertford to a large pond on the hill of Islington above the City in 1613, and through wooden pipes from there to individual subscribers in the City in 1614.
The recent quarter centenary of the River, which still delivers around 8% of London's fresh water to the East Reservoir at Stoke Newington, revived interest in this remarkably long-lived element of London's infrastructure.
The speaker was involved, not only with the celebrations of the quarter centenary, but also with a project to create a heritage interpretation, education and community use centre in the surviving historic buildings on the New River's Head in Islington.
Andrew Smith summarises the history of the River from 1607 onwards and, in view of the dedicatee of this annual lecture, briefly describes John Smeaton's role in the River's life towards the end of the 18th Century.
