Hermann Fehling was a German chemist known for his contributions to organic chemistry in the 19th century. He is best recognized for developing the Fehling's solution, a chemical reagent used to test for the presence of reducing sugars, such as glucose. This solution plays a significant role in various laboratory analyses and is still referenced in modern chemistry. Fehling's work laid the groundwork for further research in carbohydrate chemistry. His findings helped scientists better understand the properties and reactions of sugars, influencing both academic research and practical applications in fields like biochemistry and food science.
