Tadeusz Reichstein: chemist, botanist, and developer of the Reichstein process

Life and education

Reichstein was born in Włocławek, then part of Congress Poland, and spent part of his childhood in Kiev. His early schooling included time at a boarding school in Jena, within Germany. Political changes and opportunities in central Europe shaped his academic path; he moved to Switzerland as a young scientist and established a long association with research institutions in Zürich and elsewhere in Switzerland.

Research and the Reichstein process

Reichstein is best known in industrial chemistry for devising a practical, multistep method to produce vitamin C, also known chemically as ascorbic acid. The technique, now commonly called the Reichstein process, combined classical chemical transformations with microbial steps to convert simple sugars into ascorbic acid on a scale suitable for pharmaceutical and food uses. This process became the dominant industrial route to vitamin C for many decades and played a major role in making the vitamin widely available.

Work on adrenal hormones and the Nobel Prize

Beyond vitamin C, Reichstein's research touched on the chemistry of steroids and other biologically active molecules. For discoveries concerning hormones produced by the adrenal cortex, he shared the 1950 Nobel Prize in Physiology or Medicine with Edward C. Kendall and Philip S. Hench. Their combined experimental and structural work helped to clarify the nature and therapeutic potential of substances such as cortisone, which had significant impact on the treatment of inflammatory and autoimmune conditions.

Legacy, applications, and notable facts

Reichstein's methods had immediate practical influence: the vitamin C process he developed was adopted by chemical manufacturers and remained a standard for many years until newer biotechnological approaches emerged. His broader studies of natural products linked chemistry to pharmacology and botany, helping to bridge laboratory synthesis with compounds occurring in plants.

• Key contributions: creation of the Reichstein process for vitamin C, work on adrenal cortex hormones, and studies of plant-derived compounds.
• Industrial impact: large-scale synthesis of ascorbic acid for pharmaceuticals and nutrition.
• Honors: Nobel Prize in Physiology or Medicine (1950) shared with Kendall and Hench.

Reichstein spent his later years in Switzerland and died in Basel. At the time of his death he was the longest-lived Nobel laureate; that longevity record was later surpassed in 2008 by Rita Levi-Montalcini. His name persists in both scientific literature and industrial practice, and the term "Reichstein process" remains a common reference when describing early large-scale vitamin C manufacture.
