Kenelm Lee Guinness


Kenelm Edward Lee Guinness MBE was an Irish-born racing driver of the 1910s and 1920s mostly associated with Sunbeam racing cars. He set a new Land Speed Record in 1922. Also an automotive engineer, he invented and manufactured the KLG spark plug. A member of the Guinness brewing family, and a director of the company, he lived and died in Putney Vale, and was buried at the nearby cemetery, bordering Putney Heath.

Beginnings in motor racing

Guinness's interest in motor racing began whilst at Cambridge University, as riding mechanic to his elder brother Sir Algernon Guinness.
His first major race as a driver was the 1907 Isle of Man Tourist Trophy. His Darracq retired early, owing to axle failure. This involvement with the closely related Sunbeam, Talbot and Darracq marques continued throughout his career. In the same year he also took part in the Belgian Grand Prix at the Circuit des Ardennes.
Around this time he acquired space in a disused pub, 'The Bald Faced Stag' in Putney, London as a base for his motor-racing exploits.
From 1913 he was an official driver for Sunbeam, along with Henry Segrave. Sunbeam's engine designer, Louis Coatalen, became a friend and assisted his motor-racing career, driving Sunbeam or Talbot cars. This continued in 1914, 1921, 1922, 1923 and 1924 alongside such famous drivers as Jean Chassagne.

KLG spark plugs

As for many racing motorists of this era, he had commercial interests in automotive engineering; in this case being the inventor of the KLG spark plug, a brand name surviving today.
His experience in the 1912 Manx Tourist Trophy led him to develop a more reliable spark plug. The innovation of the KLG spark plug was its use of mica as an insulator. This mica was stacked in sheets and compressed by the centre electrode being tightened on a thread. These insulators gave more reliable performance than the porcelain ceramics used by others.
Production of these plugs began in a small way at 'The Bald Faced Stag', supplying other racers including Segrave and Campbell.
KLG plugs developed a particular reputation for reliability in aircraft use and were in great demand during the First World War. At the outbreak of war he joined the Royal Navy, but his work on spark plugs was considered to be more valuable to the war effort and he was asked to resign.
In 1919 he sold world distribution rights to Smiths, then sold up completely in 1927. He remained as a consultant.
KLG's reliability was particularly attractive to the land speed record contenders and their many-cylindered aero-engines, often with dual ignition systems. Segrave's 1,000HP Sunbeam required 48 spark plugs, a mis-fire amongst which could be very difficult to detect and replace on a windswept beach.

Robinhood Engineering Works

The KLG organisation now Robinhood Engineering Works outgrew its pub and moved into a purpose-built Art Deco building, where at one time 1,500 people were employed. The building was eventually demolished and an Asda store now stands on the site.

Hydro-Pulsator

He invented the first hydro-pulsator for the treatment of gums by water-jet massage.

Motor racing

1913

After the First World War, Louis Coatalen built the Sunbeam 350HP, which was powered by a V12 Manitou engine.
On 18 May 1922, Guinness used the car to set new Land Speed Records at Brooklands: the Brooklands lap record at 121.54 mph, then the flying-start land speed records over a half-mile, kilometre, mile and two miles. The fastest record being 136.05 mph for the half-mile. These were the last land speed records to be set on a racetrack rather than a beach or salt flat.
The car was later sold to Malcolm Campbell, who named it "Blue Bird" and also used it to set land speed records.
After his 1924 accident, Guinness withdrew from record-breaking as well as track competition. However, when his Sunbeam co-driver Segrave took the 1,000HP car to Daytona in 1927, Guinness accompanied him.

Yachting

Guinness' First World War Naval aspirations were assuaged a little in 1919, when he purchased a surplus minesweeper, the 'Samuel Green' that had been converted to a fishing trawler. He renamed her the 'Ocean Rover' and had her refitted as a gentleman's yacht. Guest accommodation was provided, together with a hold equipped to transport racing cars to foreign events.
In 1926, after Guinness's retirement from motor racing, he and his friend Malcolm Campbell used the yacht for a treasure-hunting trip to the Cocos Islands.

Death

After the 1924 crash, Guinness suffered head and other injuries. These other injuries may have been enough to end his racing career on their own, but the head injuries and the trauma of Barrett's death also changed his personality.
In his final months towards 1937, he was described as suffering delusions and was admitted to a nursing home. On 10 April 1937 he was found dead in a bedroom at his home near the KLG factory, having apparently gassed himself.
At the coroner's inquest, his brother Sir Algernon Guinness produced a letter that indicated the likelihood of suicide. The coroner's verdict was, "Suicide, while of unsound mind".
He was buried on 14 April at Putney Vale Cemetery, adjacent to the KLG factory.
