‎First edition thus, of the three articles that together constitute one of the most important contributions to modern Danish culture. Inscribed by Bohr (signed ""the author"") on the title-page: ""Hr. Direktør D. la Cour/ med venlig Hilsen / fra Forfatteren"". The work constitutes the first Danish translations of the present three articles: ""Atomic Theory and Mechanics"" (1925, Rosenfeld 33), ""The Quantum Postulate and the Recent Development of Atomic Theory"" (1928, Rosenfeld 37), and ""Wirkungsquantum und Naturbeschreibung"", (1929, Rosenfeld 39), here published together for the first time under the title ""Atomic Theory and the Description of Nature"" and with an introductory overview. The present collection of articles, translated into Danish, Bohr's mother tongue, constitutes an important insight into Bohr's thought and fundamental views on atomic theory and nature. The work, as it is here, has been elected as the Bohr-entry in the official list of Danish canonic literature, which collects the most important literary contributions to Danish culture. This is the only Bohr-item on the list. (see: http://www.kanonudvalget.dk). The work is inscribed to renowned Danish physicist and meteorologist Dan la Cour (1876-1942), son of the great Poul la Cour (1846-1908), who is considered the ""Danish Edison"". Dan la Cour was the assistant of Niels Bohr's father, Christian Bohr, and a well known scientist. From 1903, he was head of the department of the Meteorological Institute, and from 1923 leader thereof. From 1908 he was Associate Professor at the Polytechnic College. His original scientific works are highly respected, as are his original apparati for measuring earth magnetism which are considered highly valuable. ""His original intelligence, which in many ways resemble that of his father, also bore fruit in his patenting of various inventions: the ""Pyknoprobe"", developed to quickly determine the different layers of the sea"" a use of termite in quickly heating food and drinks out in the open under unfavourable weather conditions."" (From the Danish Encyclopaedia - own translation). He wrote a number of important and esteemed works and was member of the Danish Scientific Academy as well as many prominent international scientific commissions of meteorology and geophysics (i.e. president of the International Geodetical and Geophysical Union). He was also honorary Doctor at the George Washington University. Rosenfeld, Bohr Bibliography No. 40.‎
