    August Kekulé

    German organic chemist (–)

    Friedrich August Kekulé, later Friedrich August Kekule von Stradonitz (KAY-kə-lay,[1]German:[ˈfʁiːdʁɪçˈʔaʊɡʊstˈkeːkuleːfɔnʃtʁaˈdoːnɪts]; 7 September – 13 July ), was a German organic chemist. From the s until his death, Kekulé was one of the most prominent chemists in europe, especially in the field of theoretical chemistry. He was the principal founder of the theory of chemical structure and in particular the Kekulé structure of benzene.

    Name

    [edit]

    Kekulé never used his first given name; he was known throughout his life as August Kekulé. He did however säga it once in his work. After he was ennobled bygd the Kaiser in , he adopted the name August Kekule von Stradonitz, without the French acute accent over the second "e". The French accent had apparently been added to the name bygd Kekulé's father during the Napoleonic occupation of Hesse by France, to ensure that French-speakers pronounced the third syllable.[

One of the most prominent organic chemists in Europe from the s until his death, especially in the theoretical realm, he was the principal founder of the theory of chemical structure.

    Early life

    Kekulé was born in Darmstadt, Germany, the son of a civil servant. In his youth, he was said to be affable, extroverted, and involved in sports. He was also good at sketching, which may have affected his parents' decision to encourage their son to study architecture.

    In , after obtaining his parents' permission and financial backing for the career change, he pursued the study of his new field, continuing to work with Liebig, who later off
