Friedrich Wöhler

Friedrich Wöhler was a pioneering German chemist whose work fundamentally reshaped the field of organic chemistry. He is best known for his 1828 synthesis of urea from inorganic materials, a landmark experiment that challenged the doctrine of vitalism and demonstrated that organic compounds could be created in the laboratory. A prolific researcher and influential teacher, he also made significant contributions to inorganic chemistry, including the first isolation of the elements aluminium and beryllium, and held a long-term professorship at the University of Göttingen.

Early life and education

Born in Eschersheim, then a suburb of the Free City of Frankfurt, he initially pursued medical studies at the University of Marburg in 1820. His interest soon shifted decisively toward chemistry under the influence of Leopold Gmelin at the University of Heidelberg. After completing his medical degree in 1823, he traveled to Stockholm to study for a year under the renowned Swedish chemist Jöns Jacob Berzelius, an experience that profoundly shaped his meticulous analytical approach. This period of study with leading figures in European science provided a formidable foundation for his future experimental work.

Career and research

Following his time in Sweden, he began teaching chemistry in Berlin at the Gewerbeschule. It was here in 1827 that he successfully isolated the element aluminium by reducing aluminium chloride with potassium. The following year, he achieved his most famous result: attempting to synthesize ammonium cyanate, he instead produced urea, an organic compound found in urine. Throughout the 1830s, he held a professorship at the Polytechnic School in Kassel before succeeding Friedrich Stromeyer as professor of chemistry at the University of Göttingen in 1836, a position he held for the remainder of his career. His research was extraordinarily broad, encompassing the isolation of beryllium and yttrium, studies on benzoic acid, and extensive investigations into silicon compounds and meteorites. He maintained a lifelong and prolific correspondence with his friend and fellow chemist Justus von Liebig, with whom he collaborated on important studies of the benzoyl radical.

Wöhler and the death of vitalism

His synthesis of urea is historically celebrated for striking a decisive blow against the theory of vitalism, which held that organic matter possessed a "vital force" and could only be produced by living organisms. By creating an organic substance from the inorganic reagents potassium cyanate and ammonium sulfate, he demonstrated that the laws of chemistry governing inorganic reactions were equally applicable to organic compounds. While the philosophical impact was not immediate—debates involving figures like Berzelius continued for years—the experiment irrevocably undermined the central tenet of vitalism. This work paved the way for the rapid expansion of organic synthesis and helped establish organic chemistry as a rigorous branch of chemical science, independent of biological mystique.

Later life and legacy

He remained an active and revered figure at the University of Göttingen for decades, mentoring numerous students who would become influential chemists, such as Hermann Kolbe and Georg Ludwig Carius. His textbooks, including the widely used *Grundriss der Chemie*, educated generations of scientists. Among his many honors, he received the prestigious Copley Medal from the Royal Society in 1872. He died in Göttingen in 1882. His legacy is that of a foundational experimentalist whose work bridged the gap between inorganic and organic chemistry, transforming scientific understanding of matter and the processes of life. The classic organic reaction for synthesizing amines from alkyl halides, the Gabriel synthesis, was later developed by his student Siegmund Gabriel.

Selected works

His extensive written output includes both research papers and influential textbooks. Key publications are *Grundriss der Chemie* (1831), a standard text for many years, and *Grundriss der Organischen Chemie* (1840). His important research communications were often published in prominent journals like *Annalen der Chemie* and *Poggendorff's Annalen*. The collected correspondence between him and Justus von Liebig, published after their deaths, remains a vital historical resource for understanding the development of nineteenth-century chemistry.
