Tadeus Reichstein (1897-1996) was awarded one third of the 1950 Nobel Prize in Physiology or Medicine for discoveries relating to the hormones of the adrenal cortex, their structure, and biological effects. Together with E.C. Kendall and P.S. Hench, he isolated cortisone and discovered its therapeutic value in the treatment of rheumatoid arthritis. Reichstein also isolated and explained the constitution of aldosterone, a hormone of the adrenal cortex, which had not yet been isolated. Also, he synthesized vitamin C (ascorbic acid), independently of and concurrently with Sir Norman Haworth. The principal industrial process for the artificial synthesis of Vitamin C still bears Reichsteinâ€™s name.
