Joseph, Harry and Oliver Lucas

 Joseph Lucas was born in 1834, lived in Hockley, Birmingham and worked in tin, manufacturing lamps for ships and the new world of photography. In 1855, his wife gave birth to a son, Harry, who at the age of sixteen joined his father in the business.

It was the invention and growing ownership of bicycles that caught Harry's attention; this was surely an area of growth on which he and his father should devote their resources. Although without much formal education, Harry grasped the essentials of business.

He knew that sustainable businesses are built on quality products and this led to the famous King of the Road lamp. He was not alone supplying the bicycle trade, and competitors offered cheaper but poorer products. He addressed this by introducing a cheaper but still high quality lamp, the Lucas 90 Plus, whilst keeping the King of the Road for the discerning cyclist.

He understood that products ordered needed to be delivered on time. Here came a clash with his father who was a much more impetuous man who would be so taken over by the thrill of winning an order that he would promise the earth and offer prices with little consideration of cost. Harry kept pulling him into line.

Cash is king, and Harry understood this. It was a constant struggle for the business to have enough cash resource to expand to meet demand as well as manufacturing to fulfil orders.

Roy Church tells how Harry wrestled with finances as he focused on cash flow and just how difficult it was for a young company to grow. Yet, they acquired additional premises in 1895 and, as the work force grew, mercifully so did demand, and profits began to come through in handsome numbers – some £23,000 per year on average in the three years to 1897 when the partnership became Joseph Lucas Limited.

Harry's son, Oliver was born in 1892 and attended King Edward's school, on leaving which he joined his father in the business. During the war he would invent the OL daylight signalling lamp.

Joseph Lucas died in 1902.

Harry Lucas was quick to see the opportunities of moving into lighting and starting motor cars. There were of course others keen to enter this promising market. Roy Church mentions Rotax in Willesden in north-west London, and the larger C.A. Vandervell (CAV) in Acton in west London in which Herbert Austin held debentures.

The First World War presented challenges to the company. A major problem of which I write in my book Ordnance was that the War Office had specified Bosch Magnetos for their vehicles. The components industry pre-war had been content with this, and the ability of British companies to supply magnetos was strictly limited. One company in particular, Thomson Bennett, rose to the challenge. Harry Lucas pounced when, in 1914, the opportunity arose to purchase it. This was going to prove of massive value to Lucas in the years to come, not least in the person of Peter Bennett.

Harry was growing old and Oliver Lucas was not ready to take over; the time had come for Peter Bennett to take the tiller. He became joint managing director with Harry in 1920 and then with Oliver in 1923. Harry died in 1939.

Lucas were growing their business in a number of very focused ways. They accepted offers by smaller component manufacturers to buy their businesses, and then, a little later, agreed to buy their two larger competitors, Rotax and CAV when the latter experienced harsh trading conditions in the mid 1920s. The expanded company focussed individual parts of the business in three locations: Birmingham, Acton and Willesden. At the same time, the company was researching solutions to technical problems, such as the magneto, dynamo and starter motor.

Marketing was key and this was where Oliver stepped in. He developed good relationships with William Morris and many others. He embraced vital aspects of manufacturing. He was as interested in the manufacturing process as in the product and so achieved great economies. Above all he was committed to what we now know as life-long learning. He encouraged his managers to learn from each other and from other companies. He espoused relationships with academia including financing a chair, the Lucas Professor of Production Engineering, at the University of Birmingham.

He carried out vital research into the development and large scale manufacture of fuel injection pumps which made possible the growth of the heavy vehicle industry. During the Second World War as Director of Research and Development at the Ministry of Supply, he led the overhauling the design and production of the Cruiser tank. Tragically he died young in 1948.

I write of the growth of Lucas in How Britain Shaped the Manufacturing World and of its considerable contribution to the national effort in the Second World War in both HBSTMW and War on Wheels, Peter Bennett had been knighted in 1941 and had made his own significant contribution in a number of senior positions in the Ministry of Supply, including Director of Tanks and Vehicles. Following the death of Oliver Lucas, Peter Bennett was joined as joint managing director by Bertram Waring. He became Member of Parliament for Edgbaston in 1940 and became Parliamentary Private Secretary to the Minster of Labour in 1951-52. He was made a peer in 1953 and died in 1957.

I write of the later development of Lucas Industries in Vehicles to Vaccines.

New Book - How Manufacturing Shaped Britain

 This book sets out to discover how manufacturing shaped this island. Why manufacturing spread across the country, how it grew, why it declined and what was left.

It is looking at manufacturing through the lens of geography.

Manufacturing transformed the places where it took place. Villages became towns because millennia earlier great forests had been buried and became rich seams of coal. Tiny seaside communities surviving on fishing witnessed the building of ever larger ships carrying cargoes of coal or wool and returning with exotic goods from the east. Waring barons found their swords replaced by guns cast from ore left in the earth’s crust. Disparate communities were linked first by sea then by Roman Road, turnpike, canal, railway, road and air. New communities formed on these links.

Manufacturing places emerged close to raw materials and sources of energy. Climate and topography gathered manufacturing which thrived in local conditions. In time, as centres of population emerged, manufacturing followed to meet their every need. Inventions were pursued where skills had been nurtured.

None of this was planned, least of all two world wars which energised manufacturers across the land to war effort, leaving vast factories in their wake crying out for new uses.

Books have explored why Britain moved ahead of its great trading rivals: the Dutch, Spanish and Portuguese. And it did, only to be overtaken by America, Germany, and France, and replaced by developing countries. This left manufacturers stranded with factories and workforces no longer needed, leaving populations without work, steelworks replaced by supermarkets, factories by warehouses.

This book is for people who wish to understand what has happened.

It is available to buy on Amazon in Kindle and Paperback.

Plessey father and sons

 Allen Clark, son of Byron Clark, was born in Massachusetts in 1898 and came to England in 1905. He attended Felsted School. In the First World War he served in the London Scottish and was wounded at Cambrai in 1917. He then joined the Royal Flying Corps.

in 1920, Byron Clark bought Plessey Limited which made tools in Marylebone in London. In 1922 Plessey obtained a contract to made crystal radio sets for Marconi and I write of this in How Britain Shaped the Manufacturing World. Marconi invested in Plessey, secured seats on the board and Plessey developed a business in making radio components.

Allen is remembered by his friend Patrick Hennesey, one time boss of Ford UK, as a man dedicated to searching the world for ideas which could enable Plessey to develop.

Plessey became a public company in 1937 and I write in HBSTMW of its contribution to the national effort in the Second World War. After the war, Allen was joined by his sons John and Michael.

John was educated at Harrow and Cambridge and served in the RNVR from 1944 to 1947. He then went to learn about electronics manufacturing first at Metro-Vick and then in the USA before joining Plessey.

John had a particular interest in materials such as gallium arsenide and silicon and took on the development of the semiconductor business and master minded Plessey's research into materials at its Caswell laboratories. A plant for manufacturing pure silicon was established in 1952 but the potential for solid state technology had yet to be embraced. It wasn't until 1957 that the company began manufacture of transistors. 1966 MOS integrated circuits were produced at Swindon, making Plessey the first European manufacturer of such microcircuits.

In 1951 a Communications Division was formed, with Michael Clark at its head, and a remit to catch up with its competitors in VHF and UHF equipment. Two senior managers, John Cunningham and Raymond Brown, left Plessey to form Racal.

Allen's big break came in 1961 when Plessey took over competing telephone manufacturers Ericsson Telephone Ltd and the Automatic Telephone and Electric Company. He was knighted that same year but tragically died before the transaction completed. He was succeeded by John as chairman and Michael as managing director.

In 1965 the company reorganised into five product groups: Automation, Components, Dynamics, Electronics, Telecommunications. The company went on to develop their electronics business in defence, semiconductors and computers. I write of all of this in Vehicles to Vaccines. In 1962, Plessey had 25,000 employers and this grew to 75,000 by 1980 in a number of different locations with head office at Ilford as I wrote in How Manufacturing Shaped Britain.

GEC and Plessey merged their telecoms businesses in GPT in 1988 and in 1989 Siemens and GEC purchased the remainder of Plessey. John Clark was knighted in 1971 and died in 2001. Michael was awarded a CBE and survived his brother by nine years.
