<p>Jacob Volhard (January 14, 1834 – January 12, 1910) was a German chemist who made significant contributions to the field of organic chemistry. He is best known for the Volhard-Zelinsky halogenation, a widely used method for the introduction of halogens into organic compounds.</p><p></p><p>Volhard began his career as a chemist at the University of Berlin, where he earned his Ph.D. in chemistry in 1857. He later worked at the University of Heidelberg, where he carried out research on organic chemistry.</p><p></p><p>In 1881, Volhard and his colleague, Emil Zelinsky, published a paper describing a method for the introduction of halogens into organic compounds, known as the Volhard-Zelinsky halogenation. The method involves the reaction of an organic compound with a halogen in the presence of a metallic catalyst. The method is widely used in the synthesis of organic compounds and is considered one of the most important methods in the field of organic chemistry.</p><p></p><p>In addition to the Volhard-Zelinsky halogenation, Volhard also made important contributions to the field of organic chemistry through his research on the chemistry of nitrogen compounds and the chemistry of fats and oils. He published several books and articles on these subjects, including "Die Chemie der Stickstoffverbindungen" and "Die Chemie der Fette und Öle".</p><p></p><p>Volhard's contributions to the field of organic chemistry were groundbreaking, and his development of the Volhard-Zelinsky halogenation had a significant impact on the field. He was honored with many awards and honors for his contributions, including the Liebig Memorial Medal from the German Chemical Society.</p><p></p><p>Jacob Volhard was a pioneering chemist whose contributions to the field of organic chemistry were groundbreaking.
