John Duff
John Francis Duff was a Canadian racecar driver who won many races and has been inducted in the Canadian Motorsport Hall of Fame. He was one of only two Canadians who raced and won on England’s famous Brooklands Motor Course. The other, Kay Petre, is already an honoured member of the CMHF. Duff was the first Canadian to race in the legendary 24 Hours of Le Mans. To date, he is the only Canadian to win the overall classification at Le Mans.
Duff also held over fifty world records for speed and endurance. Those records were sanctioned by the AIACR, the forerunner of today’s FIA. They included both class and absolute records. His achievements helped make the name of the Bentley car company. Duff scored a top-ten finish in his first Indianapolis 500 and a top-three in his first board track race. Those achievements make him one of the preeminent Canadian automobile racers of the first half of the twentieth century.
Background
John Duff was born in Kiukiang, China. His parents were Canadians from Hamilton, Ontario who established a commercial outpost in nearby Kuling. As a boy, the rambunctious young Duff was sent to Hamilton for a good Victorian education. He lived there until he was sixteen. In 1912, Duff was back in Kuling. When war was declared in 1914, he travelled across Russia to England, where he joined the army. Gravely wounded at the Third Battle of Ypres, Duff was sent to a hospital in England where he met and married his nurse. In 1919, John Duff learned how to drive a car and became a dealer. In 1920, he started racing.Racing career
In 1920, Duff began his racing career at Brooklands, a 2.6 mile long concrete track with concave banking. He drove a Fiat S.61, a 10-litre chain-driven car built in 1908. By August 1920, he was lapping in the same range as Henry Segrave, one of the great Brooklands and Grand Prix drivers of the 1920s.Driving the S.61, Duff won the 75 Long Handicap at Brooklands in May 1921 at a speed of 104.19 mph. He won the 100 Long Handicap at Brooklands’ mid-summer meeting, averaging 104.85 mph. Duff was the fastest on the track for both wins. He also lost a number of races where he was the fastest. As Duff’s driving skills improved, his reputation began to put him at a disadvantage with the handicappers.
In the off-season, Duff bought another old Fiat, the 18-litre pre-war racer called "Mephistopheles". In June, he took both Fiats to the Fanoe beach speed trials in Denmark. Duff set the fastest time of the meeting with a run at 165.9 km/h. He also took a class win with the S.61 at a speed of 149.2 km/h, the third fastest speed of the meeting.
In 1922, Duff sold the S.61 and focused on making Mephistopheles faster and more reliable. Harry Ricardo made a set of aluminum pistons and raised the engine’s compression ratio. In May, Duff finished third in Brooklands’ 100 Mile Handicap. In its next race, one of the Fiat’s engine blocks detached from the crankcase. When the engine blew, the hood was torn off the car, just missing Duff’s head. Engine parts rained down on the track. Duff sold the car for scrap.
1922 saw the birth of Duff and Aldington, a dealership set up to sell the new Bentley car. Duff raced a Bentley at Brooklands. On August 28, he took a stock 3-litre model to the track where he made an attempt on the "Double Twelve" record. The car broke before he could achieve that goal but, in the process, Duff set new Class E world records for 1, 2, and 3 hours, 100 and 200 miles, and 100, 200, 300, and 400 km.
Duff returned to Brooklands on September 27–28, driving both 12 hour shifts singlehanded to take the Double 12 at an average of 86.52 mph, for a total distance of 2,082 miles. He also broke the Class E world records for 1 to 12 hours and all distances from 100 to 1,000 miles and 100 to 1,600 km. In total, he set 38 international class records. The Double 12 record was an absolute record, regardless of class. The event was depicted on the cover picture of the first edition of the Brooklands Gazette, published in July 1924.
At Brooklands’ autumn meeting, Duff appeared at the wheel of J.L. Dunne’s old 21-litre Blitzen Benz. He lost the 100 Mile Handicap to Parry Thomas, despite lapping at 114.49 mph. Unable to stop the old car at the end of the last lap, Duff shot over the top of the banking, crashing through trees and a telegraph pole outside the circuit before finally coming to rest.
Early in 1923, Duff learned of a new 24 Hour race to be held at Le Mans. He was the first entrant. W. O. Bentley, the founder and then-owner of Bentley Motors, thought it was madness and that no car would finish. In the face of Duff’s determination, he agreed to have the car prepared at the factory and let his test driver, Frank Clement, partner Duff. The Duff/Clement Bentley was one of the fastest cars, Duff setting the fastest lap at 9 mins 39 sec for the 10.726 mile lap. Rough track conditions took their toll as a flying stone holed the fuel tank, forcing Duff to run back to the pits. As only the drivers could work on the cars, Clement had to bicycle back with a can of gas to power the car back to the pits. Despite the drama, Duff and Clement finished a strong fourth. More importantly, W.O. Bentley, who only went over at the last minute, became hooked on Le Mans, the race that would make his cars famous.
Duff then took his Bentley to the Spanish Touring Car GP at Lasarte. Leading with two laps to go, he was hit in the face by a stone thrown up by a lapped car. Duff crashed into a wall, injuring his jaw and breaking some teeth. Despite that, he won first place in the 3 litre class, as he had easily outlasted and outdistanced his competition. "In token of his gallant drive Duff was awarded the 3-litre trophy anyway, there being no other finishers in the class."
By 1924, Bentley was now fully committed to Le Mans. Duff was still a private entrant, using one of the dealership’s cars. His car was prepared alongside the works entry using ideas Duff had come up with after the 1923 race. Partnered by Clement, in a race run in intense heat, Duff won handily, giving Bentley its first victory at Le Mans. In 1925, a carburetor fire ended Duff’s chances at Le Mans.
On September 9–10, 1925, Duff went to the high-banked Montlhéry track, near Paris, for an attempt at the absolute 24 Hour Record. He had a special single-seater Weymann body on his Bentley and works driver Dudley Benjafield as his co-driver. In driving rain, they did the first 12 hours at 97.7 mph but missed the 12 hour record. At 18 ½ hours, the camshaft drive failed, ending the attempt. He was able to claim two world records: 1,000 Kilometres in 6 hrs, 23 mins, 55 secs and 1,000 miles in 10 hrs 15 mins 59secs. On September 21, Duff returned to Montlhéry with Woolf Barnato as his co-driver. Driving on a damp track in heavy mist, they covered 2,280 miles in 24 hours, averaging 95.02 mph. They beat the previous record, held by the 9-litre Renault of Garfield and Plessier, by over 7 mph. Along the way, the 3-litre Bentley took 21 world records, including those for six and twelve hours, and 500, 1000, and 2000 miles.
Looking for new challenges, Duff went to America in February 1926. He signed to drive a Miller sponsored by the Elcar Automobile Company in the Indianapolis 500, following the death of Herbert Jones, who was killed attempting to qualify for the race in the Elcar Special. In a race shortened to 400 miles by rain, Duff finished 9th. The next AAA championship event was on the 1.25 mile board track at Altoona, Pennsylvania on June 12. Duff finished 3rd in the 250 mile race, two laps down. The next race was on the Rockingham board track in Salem, New Hampshire. A puncture pitched Duff’s car sideways, throwing him from the car. "John Duff of Indianapolis, Ind., wrecked his machine and suffered a broken collar bone when his car crashed through the top rail and dropped clear of the track." Duff suffered painful bone and muscle injuries, and a concussion that affected his vision. Knowing that his competitiveness would be compromised, and having promised his wife that he would quit if he suffered another serious injury, Duff retired from racing.
