Lea Valley History
Every so often in history a technological hotspot emerges – helping to drive industry and technology onward and upward. In the mid-1700s that clutch of enterprising Lancastrians John Kay, James Hargreaves and Samuel Compton were revolutionising weaving with the flying shuttle, the spinning jenny and the mule. In the 1970s it was the turn of the geeks of the US West Coast, Bill Gates, Steve Jobs, Steve Wozniak et al – as they invented personal computing and kick-started the information age.
But who would have thought that the Lea Valley, running down Tower Hamlets’ eastern boundary, was the birthplace of Britain’s own post-industrial revolution? As the title of Dr Jim Lewis’s first book suggested, it was ‘Britain’s best kept secret’. Now, in a fascinating sequel*, Dr Lewis reveals more of the developments that turned the Lea into the UK’s technological crucible.
In fact, Lewis argues, the likes of Gates wouldn’t ever have been able to make their billions from the PC were it not for a much earlier invention in the Lea Valley. In 1904 Professor Ambrose Fleming developed the diode valve. The invention not only paved the way for today’s multimedia electronics industry – it also created the platform for space travel, computers, email and the internet.
Firstly though, the diode valve gave birth to the modern wireless. So radio has its roots in the Lea Valley, and Britain’s first radio valve factory was established there in 1916, with the first television tube factory following in 1936.
But the technological developments in the Lea Valley were as diverse as they were numerous. The monorail may still seem a futuristic mode of transport, but it was developed here by Henry Robinson Palmer as long ago as 1821. This ingenious method of hanging heavy goods from the sides of a rail carriage to lower the centre of gravity meant that great weights could be smoothly shifted. The invention went into use at the Royal Victualling Yard at Deptford in 1824, with the frictionless action meaning four men could easily shift 5cwt loads of provisions from warehouse to ship.
And another welcome innovation on board ship was that of IPA (India Pale Ale). Dreamed up by George Hodgson at his Bow Brewery, it was the first beer that could be transported to the hot climes of the Empire without tainting – giving East End sailors some relief and British soldiers a welcome taste of home.
The geography of the Lea Valley reads like a Who’s Who of British industry in the late 19th and 20th centuries. Johnson Matthey, Hawker Siddeley, Reuters, Lotus Engineering, Tesco, Keith Blackman, BOC and Matchbox Cars were just a few of the innovators who built their businesses here. Petrol was not only manufactured, it also received its name here, and the British Army’s rifle of choice was, for decades, the Lee Enfield. That reliable weapon was of course manufactured in the Lea Valley.
