Comparative anatomy, embryology
Wiedersheim was greatly influenced by his father, who practiced general medicine and was also a naturalist and collector of zoological specimens; his mother, Berta Otto Wiedersheim, died after his birth. At the age of fifteen Wiedersheim devoted most of his time to the microscopic study of the freshwater hydra fusca and viridis.. Consequently his final school report in classical languages was a minor disaster. Although he wanted to study zoology, at the insistence of his father he began medical studies in October 1868 at the University of Tübingen, where he was a pupil of Leydig. In 1871 Wiedersheim transferred to the University of Würzburg to study under A. Koelliker and C. Hasse; the latter proposed to Wiedersheim a thesis on the structure of the stomach of birds, which was completed in 1872.
Wiedersheim finished his medical studies at the University of Freiburg, and became a university demonstrator and lecturer at Würzburg where he worked under Koelliker until 1876. At Würzburg he established himself as an excellent teacher of systematic and comparative anatomy. At the same time he also published papers on Comparative vertebrate anatomy. At the end of 1876 Wiedersheim was appointed associate professor of anatomy at Freiburg, and, in 1883, full professor and director of the Institute of Anatomy and Comparative Anatomy. During his early years at Freiburg, Wiedersheim began the work that led to his world-famous textbook on comparative anatomy Vergleichende Anatomie der Wirbeltiere–based on the comparison of vertebrates, and their embryologic and phylogenetic development. English editions of Comparative vertebrate Anatomy by E. N. Parker appeared in 1886 and 1897. In 1907 a rewritten and revised third edition was published. Wiedersheim’s fame as a morphologist rests on his book, and numerous students from Europe and the United States were thus attracted to the Institute.
When Wiedersheim retired at the age of seventy, he had firmly established the teaching of comparative anatomy. The respect and affection that his pupils and colleagues had for him is evident in the special issue of the Zeitschrift für Morphologie und Anthropologie (1924) published in honor of his seventy-fifth birthday. Wiedersheim was survived by his wife, Tilla Gruber. and one son.
