Johann Rudolf Glauber
1604–1670
A restless experimenter of the early modern age, he helped push chemistry away from mystery and toward practical work in the laboratory. He is best remembered for identifying sodium sulfate, later known as Glauber’s salt, and for writing widely about chemical processes and useful substances.

About the author
Born in 1604 in Karlstadt, Johann Rudolf Glauber became a German-Dutch alchemist, chemist, and apothecary whose career unfolded across a period when chemistry was still closely tied to medicine and metalworking. Rather than following a university path, he learned through practice, travel, and work in laboratories, eventually settling in Amsterdam.
Glauber is often remembered for his work on sodium sulfate, which came to be called Glauber’s salt, and for developing methods to prepare important acids and other chemical substances. Historians sometimes describe him as one of the earliest chemical engineers because he focused not just on discovery, but on how materials could be produced and used in a practical, repeatable way.
He also wrote extensively, sharing recipes, observations, and technical ideas that influenced later workers in chemistry. That mix of experiment, industry, and publication helps explain why he still stands out as an important bridge between alchemy and modern chemical science.
