Willi Hennig was a German biologist and zoologist known as the founder of phylogenetic systematics, or cladistics. While a prisoner of war in 1945, he developed his theory of cladistics, which he later published in German and English. Hennig revolutionized the understanding of evolution and systematics, specializing in dipterans. He introduced key terms like synapomorphy and contributed the auxiliary principle, emphasizing the importance of apomorphic characters in determining kinship. Hennig's progression rule in cladistics proposed that the most primitive species are located in the earliest part of a group's area.

Wilhelm Roux was a prominent German zoologist known for his groundbreaking work in experimental embryology. He made significant contributions to the understanding of how organisms develop from fertilized eggs. Roux's experiments on developing embryos laid the foundation for modern developmental biology. He was a pioneer in studying the role of various factors in embryonic development, including the concept of epigenetics. Roux's work continues to influence research in biology and medicine, shaping our understanding of how life begins and develops.

Oscar Hertwig was a prominent German embryologist and zoologist recognized for his significant contributions to developmental biology and evolution. He gained recognition for being the first to observe sexual reproduction by studying sea urchin cells through a microscope. His research and discoveries in the field of developmental biology have had a lasting impact on the scientific community. Hertwig's work paved the way for further advancements in understanding the processes of reproduction and development in various organisms, leaving a lasting legacy in the field.

Karl August Möbius was a pioneering German zoologist known for his work in ecology. He held various teaching positions, including at the Gelehrtenschule des Johanneums in Hamburg. Möbius conducted groundbreaking research on marine animals, particularly focusing on the ecological aspects of the fauna of the Kieler Bucht. He also investigated oyster farming in Northern Germany, leading to important publications on the topic. Möbius later became the director of the Zoological Collections at the Natural History Museum of Berlin and a professor at the Kaiser Wilhelm University.

Max Schultze, a German microscopic anatomist, is recognized for his significant contributions to cell theory. Through his meticulous work, he advanced the understanding of cells and their structure, laying the foundation for modern cell biology. Schultze's research focused on the microscopic examination of cells, leading to groundbreaking discoveries that revolutionized the field. His dedication to scientific inquiry and attention to detail earned him a reputation as a pioneering figure in the study of cells, leaving a lasting impact on the scientific community.

Victor Hensen was a pioneering German zoologist and marine biologist known for his significant contributions to the field of planktology. He is credited with coining the term "plankton" and establishing the groundwork for biological oceanography and quantitative research in marine ecosystems. Through his research and studies, Hensen played a crucial role in advancing our understanding of the role of plankton in marine environments, shaping the field of marine biology and inspiring future generations of scientists in the study of ocean life.

Karl Theodor Ernst von Siebold, a German zoologist and physiologist, had a significant impact on the field of biology. He is renowned for introducing the taxa Rhizopoda and Arthropoda and defining the taxon Protozoa, particularly for single-celled organisms.
