An antibody is a protein used by the immune system to identify and neutralise foreign objects like bacteria and viruses. Each antibody recognises a specific antigen unique to its target. Production of antibodies is referred to as the humoral immune system.
Rudolf Ludwig Carl Virchow was born on October 13, 1821 in the town of Schivelbein, in the German Kingdom of Prussia. Today the town is called Åwidwin and lies in Poland. His father was Carl Christian Siegfried Virchow, a farmer, and town treasurer of Schivelbein; his mother was Johanna Maria Hesse.
He developed the first systematic method of autopsy involving surgery of all body parts and microscopic examination. A number of medical terms are named after him, including Virchow's node, VirchowâRobin spaces, VirchowâSeckel syndrome, and Virchow's triad.
