The topic # 2. Wilhelm
August Oskar Hertwig (1849-1922). 1884 Wilhelm August Oskar Hertwig (1849-1922) (reference ?), the brother of Richard Karl Wilhelm Theodor von Hertwig (1850-1937), and Eduard Adolf Strasburger (1844-1912) (Strasburger, 1884), independently from each other, put forward a hypothesis of significance of the nucleus as a carrier of hereditary properties. This hypothesis was developed particularly brilliantly in theoretical works of August Weisman (1834-1914), in his theory of the germinal and somatic plasma (Weisman, 1892). Further development of the same conception is the gene theory of Thomas Hunt Morgan (1866-1945) (Morgan et al., 1915). A new field science, cytogenetics, appeared. The first systematic review of data in this field was composed by the well-known American cytologist Edmund Beecher Wilson (1856-1939) (Wilson, 1896). 1890 Wilhelm August Oskar Hertwig (1849-1922), the brother of Richard Karl Wilhelm Theodor von Hertwig (1850-1937) put forward a hypothesis of individuality of chromosomes (reference ?). Help me please with this reference... Thanks to Axel W. Bauer the reference was inserted in the description: Hertwig Oskar:
