Hans Bluntschli
Hans Bluntschli (February 19, 1877 – July 13, 1962) was a Swiss anatomist. He was born in Frankfurt and died in Bern. Education and career. In 1881, his father, who was an architect, moved the family to Zurich. From 1887 he attended the grammar school in Winterthur. The botanist Robert Keller (1854-1939) was a teacher there and exerted a great influence on the young Bluntschli, as Bluntschli himself often emphasized in later years. Keller had studied in Jena and was a big fan of Ernst Haeckel's(1834-1919) zoological and embryological theories. He received his medical degree from Heidelberg  University in 1903, and taught at multiple universities before becoming the chair of anatomy and embryology in Bern in 1933, where he succeeded Karl Wilhelm Zimmermann, and where he remained until his retirement in 1942. His contributions were concentrated on comparative anatomy, morphology and embryology, relating his findings to theories about the process of evolution. On expedition in 1931, he recovered two juvenile specimens of birds, which were identified in 1996 as a distinct species, but were later identified through genetic analysis to be specimens of white-throated oxylabes. His expeditions included the Amazon Rain Forest from 1912 to 1913 , and Madagascar from 1932 to 1933, during which he recovered the specimens now know to be white-throated oxylabes.
