The History of VDO

 

 

 
 

Progress with tradition. 

 

 

VDO is today one of the world's leading automotive suppliers and one of the largest providers of parts and services for passenger cars and commercial vehicles. The company has been a byword for progressive electronic and mechatronic solutions since the birth of the automobile.

 

The 125th anniversary of the invention of the automobile is not just a reason for celebration for the vehicle manufacturers. That is because the history of the supplier industry also began here, without which Daimler & Co would never have managed to get their "coach with combustion engine" moving in the first place. VDO can also be considered one of the pioneers of the early days of the automobile. The company is today an important brand within the Continental Group and one of the world's leading suppliers of parts and services for passenger cars and commercial vehicles. The roots of the company stretch all the way back to the birth of the automobile.

 

At the very latest, VDO became a familiar brand to every driver along with the worldwide success of the VW Beetle. It was in this vehicle that the masses first came across the three-letter trademark from 1939 onwards. It was displayed on the speedometer of the most successful car in the world, as VDO produced the speedometer exclusively for Volkswagen. However, the history of the company extends back as far as the 1920s. It was then that Otto Schulze invented the speedometer, which was manufactured by the OSA Apparate GmbH company of Frankfurt Senator Adolf Schindling from 1923 onwards. A merger with parts of Deutsche Tachometerwerke GmbH (Deuta) resulted in the formation of Vereinigte Deuta OTA in 1928. This represented the birth of VDO Tachometer AG, whose three letters established themselves worldwide in the following years as a synonym for reliable and precise measuring instruments. In 1938, VDO was the largest and most capable manufacturer of measuring instruments for motor vehicles in the whole of Europe. The Frankfurt plants alone produced over 100,000 units every year, which were supplied to almost all renowned German automotive manufacturers for installation on the production line.

 

VDO manufactured products capable of measuring and controlling almost all characteristics of passenger cars and commercial vehicles. The initial products were largely mechanical but subsequent products came to rely increasingly on electronics. The company was also able to establish itself as an instrumentation specialist for other modes of transport: ship's captains, pilots, even excavator operators and train drivers came to trust the indicators from the measurement specialist VDO.

 

The Second World War was a setback for the company because most of the production plants were destroyed. Production was restarted in 1949. The first new products after the war were speedometers for bicycles and mopeds, which developed quickly into a great success. However, measuring instruments for motor vehicles were also in high demand worldwide. The company profited from and grew with the German "economic miracle" and, alongside display instruments for bicycles and automobiles, other products were added to the range such as parking meters.

 

Now under the name of "VDO Adolf Schindling" and operating as an independent corporation since 1973, the company introduced numerous innovations which went on to enjoy worldwide success: VDO invented the electric cruise control system, installed the first quartz crystal clock directly into the cockpit, developed the instruments into a central information system with integrated on-board computer and became, for example, the first manufacturer to introduce a comprehensive head-up display.

 

After first being taken over by Mannesmann, then merging with parts of Siemens AG for several years, VDO became an important brand of the Continental AG corporation in December 2007. Today, the company is driving the change from analog to digital tachographs in commercial vehicles, is a byword for technological expertise in telematics and fleet solutions and provides an unmatched infrastructure of services for commercial passenger and goods transport.

 

Today, the VDO brand is a central pillar of the Commercial Vehicles & Aftermarket (CVAM) division of Continental and is represented worldwide with an extensive network of sales and service companies. Under the brand, Continental, as one of the worlds leading automotive suppliers, markets electronic products, systems and services which make commercial and special-purpose vehicles safer, cleaner and more economical while also allowing them to operate more efficiently on a day-to-day basis. The product range thus includes, for example, control and monitoring systems for powerplant and on-board electronics, components for instrumentation, panels and cockpits as well as fleet solutions for trucks, buses and special-purpose vehicles. Furthermore, the range also includes a wide range of products and services for specialist motor vehicle garages and spare parts for the independent retail sector and independent garages. VDO also ensures the supply of genuine parts once automotive manufacturers discontinue production of a vehicle.

The History of Smiths

 

 

 
 

If you've ever driven a British car made before the 1970s, there's a good chance that you've stared at a set of Smiths gauges. The U.K.-based company supplied speedometers, tachometers and various other gauges for the instrument panels of Austin Healey, MG, Jaguar, Rolls-Royce and just about every other British-based automobile manufacturer. 

 

Founded in London in 1851 by Samuel Smith as S. Smith and Son, the concern got its start making watches and clocks as well as selling jewellery and precious stones. Success allowed them to expand to a larger location and open additional shops in the 1870s when Samuel Smith, Jr. took over. Their reputation had grown near the end of the 19th century such that they advertised as "Watchmakers to the Admiralty and the Royal Observatories." But it was with the dawn of the automobile that Smiths really came into their own.

 

Although some sources indicate that Smiths built the first odometer in the U.K. in 1900, known as a "mileometer," they didn't start into speedometers until a few years later. This part of the business rapidly grew to become the primary concern and a new publicly traded company was established in 1914: S. Smith and Sons (Motor Accessories) Ltd, with the third generation Allan Gordon Smith as its director and also a patent holder of an early speedometer. As the automotive business took off, so, too, did the aviation business with World War I, a time when the firm supplied aircraft instrumentation, in addition to other products essential to the first mechanized war.

 

Throughout the decade following the war, Smiths' gauge business flourished, as did other facets of their automobile supply business. They purchased M.L. Magneto in 1919 and K.L.G. Sparking Plugs in 1927, the same year they acquired the rights to produce Jaeger instrumentation for the British market under license. British Jaeger gauges are essentially re-branded Smiths gauges. But in 1930, Smiths sold off all of their businesses related to lighting, starting and ignition, including M.L. Magneto, to Lucas, and the two companies agreed not to manufacture products that the other already had an established foothold in. It's hard to believe such a deal would pass antitrust muster today. If you've ever wondered why a car full of Smiths gauges typically had a Lucas ammeter, it's because Smiths left that business to Lucas.

 

With the Second World War, Smiths continued to prosper. In 1939, the fourth generation director, Ralph Gordon Smith, presciently opened a factory in Cheltenham, some 100 miles west of London, fearing exposure to bombing at their main plant, which was partially damaged during the Battle of Britain in 1940. During the war, Smiths re-organized once again, this time changing the company name to S. Smith and Sons (England) Ltd, with four divisions: Motor Accessories, Industrial Instruments, Aircraft Instruments and English Clocks. By the 1960s, with an additional marine division, Smiths automotive division was making spark plugs, car radios and entire instrument panels, and the name changed to Smiths Industries.

 

As with many facets of British industry in the 1970s, the automobile business took a beating, and by 1984, Smiths sold off the motoring division to Lucas, who in turn flipped it to another company before VDO acquired it some years later. The German gauge maker, having acquired a rival, decided to do away with the wholly owned division and shut down the Welsh factory. The local management team acquired the operations and formed Caerbont Automotive Instruments which continues to engineer and manufacture Smiths gauges in Wales.

The History of Jaeger Car Clocks

 

 

 
 

The history of the development of the Jaeger car clocks begins back in 1880 when the great French watchmaker Edmond Jaeger (1858-1922) established his company in Paris. He devoted his life to developing mechanisms for measuring speeds and was a pioneer in the development of chronometers, tachometers and automobile and cockpit clocks. 

 

At the beginning of World War I, Edmond Jaeger collaborated with Jacques-David LeCoultre to develop onboard instruments intended for aviation. The speedometers and tachometers manufactured in the Vallée de Joux soon came to equip most planes in the French, English and U.S. air forces of this period. These instruments were so highly regarded during the first world war that many Germans equipped their planes with Jaeger instruments obtained from downed English and French planes. It is said that one of these instruments was found fitted to the plane of the famous German ace Manfred von Richtofen (the Red Baron) when it was shot down.

At the start of the 1920s, Jaeger and LeCoultre decided to utilise their experience and skill in producing aviation instruments in a new venture involving the production of dashboard instruments for the automobile industry. In addition to producing autotmobile speedometers and tachometers they also began to produce high quality 4 and 8-day automobile clocks. This new venture proved to be remarkably successful with large numbers of automobile instruments produced and exported throughout the European and American automobile markets. To avoid the protectionist measures adopted by the British government, the two entrepreneurs founded a company in London specialising in dashboard instruments, which at one point employed up to 700 people. In parallel, they laid the foundations in Paris for the future Jaeger factories in Levallois, which would host a 1800-strong workforce.
