Werner von Bolton (8. April 1868 – 28. October 1912) was a German chemist and materials scientist. He devised a technique for producing filaments for incandescent light bulb made out of tantalum in 1902.

Life[edit]

Werner von Bolton was born in Tbilisi, Georgia. He went on to study Chemistry at the Technische Hochschule Berlin and in Leipzig. Post-Graduation, von Bolton worked at the company Siemens & Halske in Berlin. In 1895 he achieved his doctorate.

In 1902 von Bolton detected the benefits of using Tantalium (Ta.)as a material in the production of filaments. Tantalium allowed for a greater luminosity with lower energy consumption when compared with previous alternatives such as coal.[1]

In 1905, Siemens & Halske awarded von Bolton the position of director of the first central laboratory of the company, later the Physics and Chemistry laboratory.

After 1910, the bulbs with a tantalium filament were replaced by those with a tungsten filament.

Von Bolton died in Berlin on 28 October, 1912. He is honoured with the Boltonstraße, a street named after him in Siemensstadt, an area of Berlin's Spandau district.
