History of Heraeus Refining

---

Wilhelm Carl Heraeus (1827-1904) (pictured right) was the founder of Heraeus.

Wilhelm came from a family of pharmacists, his family owned and operated, the Einhorn Apothecary (Unicorn pharmacy) in Hanau, Germany.  The family's pharmacy opened in 1660.

As a young man, Wilhelm went to the University of Göttingen, where he studied chemistry and pharmaceuticals.

In 1851, at the age of 24, Wilhelm Heraeus took over his father's pharmacy.

Shortly after taking over the pharmacy, Wilhelm Heraeus discovered a way to melt platinum in large quantities.

In the 1800's, Hanau, Germany was a town of goldsmiths.

Goldsmiths in the area were perplexed because their customers were demanding platinum jewelry, but no one was able to melt platinum in large enough quantities to support demand.

Several of these goldsmiths complained to Wilhelm Heraeus about their problems with melting platinum.

At the time, goldsmiths were unable to produce a flame hot enough to melt platinum, platinum has a melting temperature of 1,769°C (degrees Celsius), this is well above gold's melting temperature of 1,064°C.

In 1856, through a series of experiments, Wilhelm Heraeus figured out how to melt large volumes platinum, without impurities, using a oxhydrogen gas flame.

In his first successful experiment, he melted two kilograms of platinum.

Wilhelm invented his own oxyhydrogen gas-burner which brought industries from goldsmiths to chemical laboratories calling on him to use his methods for melting platinum.

This gave birth to the "first German platinum melting house" and made the Heraeus business grow far beyond its pharmaceutical roots.

At the turn of the century, the sons of Wilhelm Carl Heraeus, Wilhelm and Heinrich Heraeus took over as managers of the company and in 1904, after their father's death, they inherited the company.

The two brothers continued to follow in their father's footsteps by emphasizing on the company's research and development, ultimately expanding Heraeus's refining market exposure. 

In 1909, they hired Dr. Richard Küch, a physicist and chemist.

During his career, Dr. Küch invented a way of creating high-purity, bubble free, quartz glass by melting rock crystal with an oxy-hydrogen gas-burner. 

Dr. Küch's inventions, and the Heraeus brothers focus on research and development (R&D), laid the foundation for the technologies the company specializes in today.

During the first half of the 20th century, the Heraeus company went through many hardships, from WWI and hyperinflation to bombing raids on its facilities during WWII, but through hard work, the family kept the company alive.

After World War II was over, the company was into its second and third generations of the Heraeus family running the company. 

During this time, they continued to focus on research and development of new technologies.  In addition, they expanded the company world-wide opening offices in the United States, and Japan.

Heraeus
4th Generation & Future

---

In 1983, Dr. Jürgen Heraeus, a fourth generation - Heraeus, was appointed to lead the Heraeus company.

Under his leadership, he re-organized the company into several decentralized, operating companies.

In 1986, Heraeus formed a 50% joint venture with UBS, UBS had previously bought 100% of a independent refiner, based in Switzerland, known as "Agore SA."

The venture gave birth to the company Agore-Heraeus SA, and later in 1999, the Agore-Heraeus SA purchased the other 50% of the company from UBS, making Agore-Heraeus SA.

In March of 2017, Heraeus aquired 100% of Agore-Heraeus shares making the company a full Heraeus subsidiary.  See info here.

Interesting Fact: In 1952, when it was an independent refiner,

Argor SA produced their first minted bullion bars.

Serial Numbers - Heraeus Bullion

---

In General, serial numbers on bars, are put on bars and or assay cards as a service for the individual investor; to help them to keep track of the bullion they own.

Before 2011, it was not common practice for Heraeus to place serial numbers on bullion.

On a question & answer section on Heraeus's website, they answer some questions often asked by bullion investors below:

Heraeus : Q & A

Q: Can I use the serial number to verify the precious metal bars are genuine?

A: No. The genuineness of the bars cannot be verified by means of the serial number. However, the serial number links the bar to its certificate. All Heraeus gold bars have been delivered with a certificate since 2011.

Q: Do all Heraeus precious metal bars bear a serial number?

A: All gold, platinum and palladium bars produced since 2011 have serial numbers. However, there is some deviation from this for older bars; some of these do not have a serial number. Heraeus Silver Bars, as a rule, have no serial numbers.
