Events Occured in Scienctist Life


He was ennobled in the Kingdom of Bavaria in 1885 and was the 1905 recipient of the Nobel Prize in Chemistry.


Baeyer had four sisters: Clara (born 1826)


Emma (born 1831), Johanna (Jeanette) (born 1839), Adelaide (died 1843) and two brothers: Georg (born 1829) and Edward (born 1832).


After graduating from secondary school in 1853, he entered the Berlin University to study physics and mathematics.


A stint in the Prussian army interrupted his study until 1856, when he returned to academia at the University of Heidelberg, intending to study chemistry under Robert Bunsen.


He continued to collaborate with Kekule even after he returned to Berlin in 1858 for the completion of his doctorate on arsenic methyl chloride, or cacodylic.


He became a lecturer at the Berlin Gewerbeinstitut (Royal Trade Academy) in 1860 and a Professor at the University of Strasbourg in 1871.


In 1875, he succeeded Justus von Liebig as Chemistry Professor at the University of Munich.


Baeyer's chief achievements include the synthesis and description of the plant dye indigo, the discovery of the phthalein dyes, and the investigation of polyacetylenes, oxonium salts, nitroso compounds (1869) and uric acid derivatives (1860 and onwards) (including the discovery of barbituric acid (1864), the parent compound of the barbiturates).


He was the first to propose the correct formula for indole in 1869, after publishing the first synthesis three years earlier.


In 1871 he discovered the synthesis of phenolphthalein by condensation of phthalic anhydride with two equivalents of phenol under acidic conditions (hence the name).


The term fluorescein would not start to be used until 1878.


In 1872 he experimented with phenol and formaldehyde; the resinous product was a precursor for Leo Baekeland's later commercialization of Bakelite.


In 1881 the Royal Society of London awarded Baeyer the Davy Medal for his work with indigo.


He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1884.


In 1905 he was awarded the Nobel Prize in Chemistry "in recognition of his services in the advancement of organic chemistry and the chemical industry, through his work on organic dyes and hydroaromatic compounds", and he continued in full active work as one of the best-known teachers in the world of organic chemistry up to within a year of his death.


Liebig Medal, awarded by the German Chemical Society 1905:


Nobel Prize in ChemistrySince 1911, is established the Adolf von Baeyer Medal which is awarded annually.


He was elected member to several scientific academies, in 1884 to the Prussian Academy of Sciences and 1885 a foreign member of the Royal Society.


In 2009 von Baeyer lunar crater was named after him.
