Annual Report of the Council. Hii. 



Professor Albert Ladenburg, organic chemist, was born 

 2nd July, 1842, at Mannheim. He studied at Heidelberg, at 

 Bonn and at Paris. In 1870 he became privat-docent in the 

 University of Heidelberg, and in 1874 was elected Professor of 

 Chemistry in the University of Kiel. For many years he was 

 Professor of Chemistry at Breslau, where he died. All who 

 were brought into contact with Ladenburg were attracted by 

 the intense interest he showed in all scientific problems, and by 

 his vitality and social qualities. He was universally popular. 



He became known to a wide circle of readers through his 

 " History of the Development of Chemistry since the Time of 

 Lavoisier," which has gone through several German editions and 

 has been translated into English by Dr. Dobbin. This work 

 contains a very concise account of the development of modern 

 chemistry (with copious references to original authorities) and 

 is eminently free from "national" bias. 



His " Theory of Aromatic Compounds " contains a clear 

 account of Ladenburg's important contributions to the con- 

 stitution of benzene and naphthalene derivatives, with a reasoned 

 criticism of the defects of Kekule's hexagon formula for benzene. 



Ladenburg's " Handbook of Chemistry," in 3 \ olumes, is a 

 well-known text-book. H. B. D.
