Friedrich Tiedemann
Friedrich Tiedemann ( born August 23, 1781 Kassel, † January 22, 1861 in Munich) was a German anatomist and physiologist.
Life and work
Tiedemann studied in Marburg, Würzburg, Paris and Göttingen and received in 1806 a professor of anatomy and zoology in Landshut. From 1816 until his retirement in 1849 he was professor of anatomy and physiology in Heidelberg. He was followed there as director of the Anatomical Institute successor of Jacob Fidelis Ackermann, on Tiedemann Jacob Henle.
Soon after his appointment to Landshut 1808-1814 he published a three-volume work Zoology, designed to his lectures. In it, he is in the first band to humans and the mammals, the 2nd & 3rd from the birds. In 1816 appeared the anatomy of the brain formation history Tiedemann compared the embryonic brain development in vertebrates and humans and found matching development principles. He was one of the pioneers of the theory of evolution. Along with Leopold Gmelin he published in his time in Heidelberg fundamental work on the digestive system of humans and animals ( The digestion after attempts from 1826 to 1827 ).
Tiedemann was a staunch supporter of experimental science and rejected the romantic nature of research in the tradition of natural philosophy from Schelling. With its use against racism, he was ahead of his time. In the treatise On the Brain of the Negro, Compared with did of the European and the Orang- Outang (1836 ), he confronted the contemporary prejudices and noted that there are no innate intellectual differences between people of different skin color. As the only publication Tiedemann's this essay first appeared in the English language ( in the " Philosophical Transactions of the Royal Society of London " ) and in 1837 in Heidelberg under the title The brain of the Negro compared with that of the European and orang- outangs; Tiedemann wanted to celebrate the abolition of slavery by the British Government ( 1833).
Tiedemann was married since 1807 with Jenny Rose of Holzing ( 1791-1871 ). From the marriage seven children were born, three of whom died young. The three sons took 1848/49 at the Baden Revolution in part; the oldest, Gustav, was shot dead in 1849, the other two emigrated to the United States. His daughter Cunegonde was married in first marriage to Vincent Fohmann, in second marriage with Theodor von Bischoff.
From Tiedemann comes the saying
" Doctors without anatomy are moles the same: they work in the dark, and her hands work days are mounds of earth. "
