The story

DSM was formed by the Dutch state in 1902 to mine coal reserves in southern Limburg and although the company had diversified into commodity chemicals and petrochemicals by 1973, when the last mine closed, DSM retains a link to its origins by continuing to use the initials, originally an abbreviation for Dutch State Mines, to this day.

During World War II researchers worked on penicillin. The code name Bacinol was used to keep the research secret from the Germans. The research was done at the company Koninklijke Nederlandsche Gist- en Spiritusfabriek, 'Royal Dutch Yeast and Spirits Factory', later becoming DSM Sinochem Pharmaceuticals, in Delft.

In 1989, the government floated 70% of its shares in the company on the Amsterdam Stock Exchange (now Euronext Amsterdam) with the remaining 30% floated in 1996, thereby completing DSM's privatisation. The 21st century has seen DSM follow successive five-year strategic periods of portfolio transformation and internationalisation involving acquisitions, divestments and partnerships. In 2001, 48% of DSM's workforce was based in the Netherlands; in 2017, this was 18%.

In 2022, DSM and Swiss privately owned group Firmenich announced their intention to form a "merger of equals" to form DSM-Firmenich. The merger was completed in May 2023.
