Quick Summary

Leopold Gmelin was a German chemist who lived from 1788 to 1853. He is known for developing Gmelin's test, a method used to detect bile pigments in substances like urine. This test involves mixing the sample with nitric acid containing nitrous acid, and a positive result is indicated by a series of colors appearing at the junction of the two liquids. Gmelin's work contributed to the field of chemistry during a period of significant advancement, alongside contemporaries like Jöns Jacob Berzelius, who is considered one of the founders of modern chemistry.12
