History


1851 – 1895

In 1851, at the age of 24, the pharmacist and chemist Wilhelm Carl Heraeus took over his father's " Einhorn Apothecary" in Hanau. The business had been in the ownership of the Heraeus family since 1660, acting as an official court

, Wilhelm Carl Heraeus understood the problems faced by goldsmiths. After a series of experiments, he first succeeded in melting platinum in large volumes and producing pure metal in 1856, using his own specially developed oxyhydrogen blowpipe. It was already known at the time that platinum could be melted using oxyhydrogen, a mixture of

gas – but until then, only small quantities had been melted in a laboratory. With his gas blowpipe, Heraeus could produce enough oxyhydrogen and a large enough flame front to melt several kilograms of platinum-containing materials. This pioneering achievement enabled Heraeus to found the "W.C. Heraeus First German Platinum Smelters", supplying a variety of customers such as goldsmith workshops and jewellery factories throughout the world, as well as dental manufacturers, chemistry laboratories and other branches of industry. In 1857, W.C. Heraeus succeeded in producing around 30

s of pure platinum. By 1896, he was melting and processing more than 1000 kilograms of pure platinum.

s and vessels used in chemistry and physics. As early as the 19th century, platinum had already been used in locking pins to hold false teeth in place. Platinum was also used to make filaments in light bulbs and non-corrosive electrical contacts in telephones. As the company continued to expand, it needed new premises – so in 1896, the W.C. Heraeus Platinum Smelting Factory was established just outside Hanau, employing 40 people. Two years later, Wilhelm and Heinrich Heraeus, the two sons of the company founder, took over as managers. They were responsible for pushing ahead with research and development, and bringing on board a former school friend, the physicist and chemist Richard Küch. Küch, who became a director in 1909, had many contacts in the world of science and continued to carry out fundamental research, resulting in further growth in the company. Among his achievements were the development of a process to melt rock crystal at around 2000 °C to produce quartz glass. The quartz glass produced by the company was almost entirely free of defects and was of outstanding purity. It is still used in medicine today and is a highly sought-after material in manufacturing on account of its translucence and resistance to heat and acids. With the advent of ceramic colours, more and more platinum was needed for production processes and Heraeus started supplying products to the electrochemical and plastics industries. By the beginning of the 20th century, a major platinum processing boom was underway, caused by demand in the chemicals industry for large volumes of platinum thermocouples and platinum-rhodium

s needed to produce nitric acid. One of the most significant technical innovations in metal processing is credited to Heraeus: the melting of metals under vacuum. Heraeus Vacuumschmelze and Doctor Wilhelm Rohn applied for a patent on this process on 12 January 1918 and were granted a German patent DE 345161. Heraeus was subsequently granted British patent GB 138648, Swiss patent CH 89145, and several French patents on the process. For a short time, Heraeus set up an independent division dedicated to this technology, ‘Heraeus Vacuum Smelting’, which registered 84 German patents in 10 years.


1927 – 1945

The third generation of the family took over the business in 1927, under Wilhelm Heinrich Heraeus and his cousin Reinhard Heraeus, who remained at the helm of the business for nearly 40 years. During this time, Heraeus tapped into a variety of new material discoveries. For example, they started producing the first dental

1945 – 1983

During German reconstruction, the company turned its attention back to its established products and expanding new production facilities. The first steps towards expanding internationally and entering foreign markets had already been laid at the beginning of the 20th century by the company's founder. The company re-established its network of contacts after the Second World War, allowing it to gain new customers in the American market for quartz glass for optical applications.

. Heraeus also entered strategically important markets, such as through the acquisition of Electro-Nite. As the company grew, sales and operating profits reflected its standing as an international group. By 2001, sales outside Germany first broke the 74% mark. To exploit synergies throughout the group, Heraeus refocused its activities on core business, resulting in the setting up of Heraeus Noblelight as an independent business in 2001. The Heraeus Med part of the company was sold in 2002, as were the group's shares in Kendro Laboratory Products. At the same time, W. C.

In October 2018, Heraeus extended its sales channels in Germany by opening the online platform Heraeus-Gold.de in co-operation with the precious metals trader Ophirum GmbH. The platform allows retail customers to buy Heraeus precious metal bars and a variety of popular coins.

The company owned 84 German patents between 1923 and 1933, resulting in 101 foreign registrations. Due to the increasingly high cost of investment and the different nature of this area of the business compared to the rest of the company, Heraeus sold its Vacuum Smelting business to

Building on the know-how in handling high temperatures for chemical processes, Richard Küch, a researcher at the Heraeus Platinum Smelting Factory, was able to produce quartz glass of very high purity, which is still the material of choice for combustion tubes used in modern combustion analyzers. Richard Küch's invention together with the experience in high temperature furnace technology resulted in the commercial production of automated and semi-automated elemental analyzers. Due to the too low profitability and different nature compared to the precious metal core business of Heraeus, the Analytical Technology Division was sold in 1995 to form Elementar.

Quartz glass

Heraeus began to continuously expand its product portfolio starting at the turn of the 20th century, moving into areas such as the production of optical instruments, infrared emitters and laboratory equipment. It produced plates, prisms and

s set up on the moon during the Apollo landings. These were used to measure the exact distance between the earth and the moon and are still in use today. Heraeus also developed a new process for making high-quality synthetic quartz glass from silicon tetrachloride. In the late 1960s, this opened up a completely new market for the company: quartz fibre technology for the optical transmission of data in the telecommunications industry, followed by product developments in the field of optical fibres in 1972. In 1986, the first synthetic waveguide tubes were developed, and in 1992, production of synthetic quartz glass began in Bitterfeld. Heraeus has established itself as a supplier of devices and optical components for the semiconductor industry.


Speciality lighting

In 1904, Richard Küch discovered that evaporated quicksilver (mercury) in a quartz tube acted as an intense light source when stimulated with electricity. In light of this discovery, Heraeus joined forces with
AEG Allgemeine Elektricitäts-Gesellschaft AG (AEG; ) was a German producer of electrical equipment founded in Berlin as the ''Deutsche Edison-Gesellschaft für angewandte Elektricität'' in 1883 by Emil Rathenau. During the Second World War, ...
and founded a quartz lamp company, culminating in the development of the ‘Original Hanau Synthetic Sunlamp’ which flooded onto the German market as early as the 1930s. By the 1950s, the tanning lamp had become a popular consumer electronics item. After buying out AEG in 1973, a number of newly developed products were added to the range. Heraeus Noblelight now supplies infrared and ultraviolet emitters as well as UV-LEDs to a variety of industries, for use in automotive production, printing, plastics and semiconductors, analytical instruments, laser and environmental technology in solariums, and water and air treatment.

wires under the directorship of Richard Küch. The technology still forms the basis of Heraeus temperature measurement technology today. By the mid-1960s, analysis technology was added to the product portfolio. After the takeover of the Belgian Electro-Nite Group in 1987, immersion thermocouples and gas probes were added to Heraeus's array of measurement technology for use in the steel and aluminium industry. In 1997, the company founded Heraeus Sensor-Nite, specialised in temperature sensors needed in platinum thin-film technology for use in automotive construction, electronics and household appliances.
