Career
Jenkinson became a motor sport enthusiast in the mid-1930s:
"In 1936 I saw a racing car "in the flesh" or should I say "in the metal," for the first time, that was an E.R.A. at the schoolboys' Exhibition. Later in the year, whilst staying at Brighton, I found that the Lewes Speed Trials were quite near, so off I went to find the venue. It was there that I first saw racing-cars in action, what a thrill!"
Jenkinson was studying engineering at the
Regent Street Polytechnic when the

Farnborough. This brought him into contact with
Bill Boddy, editor of ''Motor Sport'', and other enthusiasts. In 1943 ''Motor Sport'' reported: "D.S. Jenkinson has constructed himself a very nice motor-bicycle of Norton parts, with taper forks, much of the work being accomplished by torch-light in a small shed."
After the war Jenkinson started competing on two and four wheels, but he lacked the funds to race regularly. He found that acting as
sidecar passenger to top riders enabled him to both enjoy top-level European competition himself while being paid and to scratch a living writing about it – he was passenger to

Marcel Masuy. He competed as a sidecar passenger the following two seasons, latterly for BMW. He was 'given" a BMW R67 motorcycle for his personal use by the factory and with a sidecar attached used this to travel to report on racing throughout Europe. Jenkinson rarely wrote about his personal life but mentioned how he would pick up Mike Hawthorn, living nearby, who would ride it with Jenks as passenger.
Jenkinson abandoned front-line competition to become Continental Correspondent for ''Motor Sport''. He spent his summers touring Europe and his winters in a succession of 'digs' in England; Jenks eventually settled near

in a tiny run-down house with no mains electricity or water, largely full of his archives and of parts of vehicles he was 'fettling'. He was legendary in the sport for the lack of basic domestic amenities in his home; to Jenks nothing mattered but racing. He became accepted as the 'elder statesman' of British racing journalists due to his closeness to the teams and drivers, his conversational writing style and his obvious and enduring passion for the sport.

. Jenkinson and Moss together went on to beat the five time Formula One World Champion
Juan Manuel Fangio to win the race by 32 minutes, in a Mercedes 300 SLR. This is one of the first examples of motoring journalists being an active part on what they are reporting. Jenkinson was one of the first ex competitors to go into reporting and journalism, a commonplace in today's coverage of Formula One with the likes of

One of Jenks' most famous exploits was road-testing an unregistered, unsilenced and very much not road-legal
Lotus Formula Two car on the roads near his Hampshire home on Christmas Day 1958, the logic being that the roads would be quiet and few police would be active.
As well as his journalism, Jenkinson went on to write several other motorsports books about Porsche,

. A compilation of some of his best pieces, and biographical articles about him, was published soon after his death as ''Jenks: A Passion For Motor Sport''.
For many years in the 1950s he produced an annual ''Racing Car Review'' for ''Motor Sport'', but stopped doing so as he became increasingly disgruntled with the discrepancies between the chassis numbers teams quoted and what was actually being raced; rather than compromise his journalistic integrity, Jenkinson simply stopped producing the books.
Jenkinson also developed the classification of a driver's effort into "tenths". 10/10ths being the highest, attained by only a few drivers in history; the ability to 'Tiger' (to race at ten-tenths and achieve feats that other drivers would find impossible) was seen as crucial for a champion.
In the sixties Jenkinson did much to promote the sport of drag racing in the pages of ''Motor Sport'' magazine. On 14 September 1963 he rode his NorBSA motorcycle, a
BSA Gold Star 500 cc engine in a modified and lowered
Norton frame, at the
Brighton Speed Trials. He drove an
Allard Dragon dragster and also rode a 648 cc Triumph
sprint motorcycle in the 1965 Drag Festival.
[2nd International Dragfest Official Programme.] He remained a motorcycle enthusiast, and competed in hillclimbs and sprints on his own
Tribsa hybrid well into his seventies. As ''DSJ'' he contributed regular columns and features for several decades to ''Motor Sports sister magazine ''Motorcycle Sport'' run from the same offices at Standard House.
Later life
In his later years, he became involved with
Brooklands Museum and was involved in several adventurous operations, including exploring sealed up underground air raid shelters. Despite his advanced years, he worked as hard as any of the others involved and never asked for or received any special treatment.
Jenkinson suffered a series of strokes in 1996 and moved to a home administered by the motor industry benevolent fund (BEN). He died on 29 November 1996.
