Albert von Kolliker
Albert von Kölliker (also before honoured Albert Kölliker, Rudolf Albert Kölliker, 1817-1905) had a distinguished undergraduate career starting with invertebrates and finally graduated in medicine from Heidelberg in 1842. Two years later he was chair at Zurich as professor extraordinary of physiology and comparative anatomy before moving in 1847 to Würzburg where he remained. He advanced histology and embryology, describing first mitochondria, osteoclasts and many other cells accumulating in a classic textbook on microscopical anatomy in 1850. He more or less defined the histological structure of the central nervous system.
