Hermann C. Starck founded H.C. Starck in 1920, initially as a family-run trading and processing firm focused on ores and specialty chemicals, later expanding into tungsten, molybdenum, tantalum, and niobium processing.

Founder and vision

Hermann C. Starck identified post‑WWI demand for high‑melting‑point metals and built a vertically integrated processing business.

Initial ownership

Ownership was concentrated within the Starck family and close associates under a traditional European family business model.

Early activities

The firm traded ores and produced specialty chemicals, then scaled into refractory metals processing including tungsten and tantalum.

Growth and industrial role

By mid‑20th century the company became a vital industrial supplier for aerospace, tooling and electronics sectors.

Capital demands

Metallurgical processing proved capital‑intensive, prompting the need for institutional backing beyond family capital.

1986 ownership change

In 1986 Bayer AG acquired 100 percent of H.C. Starck, ending family ownership and providing significant R&D and financial resources.

Under Bayer the company’s governance was professionalized and R&D funding grew, while the focus on refractory metals remained central to the firm’s strategy.
