&lt;br /&gt;
As one of the product design icons of the 20th century, the Anglepoise lamp has suffered few design changes and still sports its original lines. It was invented in England by George Carwardine almost as a useful application of an ingenious spring, crank and lever mechanism that he had invented while working in the car industry.&lt;br /&gt;
&lt;br /&gt;
Born in bath, England, in 1887, Carwardine began life as an apprentice automotive engineer at the Horstmann Car company. Having risen through the ranks to chief designer, he set up his own car suspension systems consultancy (Cardine Accessories) in 1924. Although he returned for another stint at Horstmann, the company went bankrupt and Carwardine found he had the time to spend in his garden workshop developing his own designs.&lt;br /&gt;
&lt;br /&gt;
Carwardine’s specialist knowledge of springs allowed him to develop a mechanism involving pivoting arms supported by a sequence of springs. This allowed the mechanism to be moved with the lightest of touches in x, y and z directions, yet be so well balanced it could remain stationary at any chosen point. The mechanism became the blueprint for what would become the Anglepoise lamp.&lt;br /&gt;
&lt;br /&gt;
Carwardine patented his invention in 1932 and began manufacture of the four-spring model in 1933 calling it the Model 1208. However, such was the success of the lamp, demand proved too high and outstripped Cawardine’s small-scale manufacturing capacity. So, in 1934 he turned to specialist spring manufacturer Herbert Terry &amp;amp;amp; Sons who already supplied the springs for his lamps, and to whom he would sell the manufacturing rights in 1934.&lt;br /&gt;
&lt;br /&gt;
Originally designed for industrial applications, further work with Terry’s saw the creation of a slightly modified, lighter three-spring version (model 1227) for home and office use. The lamp, which he registered in 1947, and in the US in 1950, was eventually to become known as Terry’s Anglepoise, which the company still produces today.&lt;br /&gt;
&lt;br /&gt;
Originally, Carwardine named the lamp ‘equipoise’ as it comprised four springs held in perfect equipoise to maintain the required position. However, he was unable to obtain the trademark as ‘equipoise was already a word in use as part of everyday language. So, instead he registered the trademark Anglepoise in 1947.&lt;br /&gt;
&lt;br /&gt;
Having achieved iconic status, the Anglepoise like most products has undergone a process of continuous development. To the original design, Terry’s has added extended collections by various well-known industrial product designers, including Sir Kenneth Grange, and has also collaborated with the renowned designers Paul Smith and Margaret Howell.&lt;br /&gt;
&lt;br /&gt;
Today, Anglepoise lamps can be found in homes, offices, restaurants, bars and hotels in more than 50 countries.&lt;br /&gt;
