August Kekule von Stradonitz (born Sept. 7, 1829, Darmstadt, Hesse—died July 13, 1896, Bonn, Ger.) was a German chemist who established the foundation for the structural theory in organic chemistry. Kekule was born into an upper-middle-class family of civil servants and as a schoolboy demonstrated an aptitude for art and languages, as well as ...

August Kekulé was born on September 7, 1829 in Darmstadt as son of a civil servant. After graduating from secondary school, in 1847 he attended the University of Giessen. Because he was a gifted draughtsman and his father was a close friend of famous architects, he began to study architecture with Hugo von Ritgen at the University of Giessen. He th...
Kekulé was the principal formulator of the theory of chemical structure and in his work, he was highly influenced by the work of Williamson, Edward Frankland, William Odling, Auguste Laurent, and Charles Adolphe Wurtz. The famous theory covers three main parts, the idea of atomic valence, the ability of carbon atoms to link to each other and the de...
Kekulé’s idea of assigning certain atoms to certain positions within the molecule, and schematically connecting them was mainly based on chemical reactions he observed. One of the main ideas about his structural chemistry was that the number of valences of a given element was invariant. However, numerous exceptions followed and it was then found ou...
To one of Kekulé’s biggest contributions to chemistry belongs his work on the structure of benzene. His first paper on the topic was published in 1865 and in it, he suggested that the structure contained a six-membered ring of carbon atoms with alternating single and double bonds. After this work by Kekulé, a new understanding of benzene, and hence...
After a measles illness that had seriously affected his health, he turned increasingly to publishing his work. Many of his papers appeared in the Annals of Chemistry and Pharmacy. His most influential work was the unfinished Textbook of Organic Chemistry, whose four volumes were published in 1859 (reprints 1861 and 1867), 1866, 1882 and 1887. Kekul...

Known for his discoveries in organic chemistry, Fredrich August Kekule lived from the early to late 1800s. In this lesson, it covers the life and contributions of Fredrich August Kekule.
May 23, 2018 · The German chemist Friedrich August Kekulé (1829-1896) was the founder of structural organic chemistry. August Kekulé, later Kekulé von Stradonitz, was born on Sept. 7, 1829, in the city of Darmstadt. After studies in the local gymnasium, young August, obedient to his father's wishes, enrolled in the school of architecture at the University ...

Sep 7, 2020 · Today marks the anniversary of the birth of August Kekulé, most famous for his proposed structure for the benzene molecule. This graphic looks at his structure and its limitations and shows how later work improved upon his initial proposal. More detail on the limitations of Kekulé’s structure, and how Lonsdale’s structure solved these ...
