Meinhard von Pfaundler (name sometimes given as Meinhard Pfaundler von Hadermur); (7 June 1872 – 20 June 1947) was an Austrian pediatrician born in Innsbruck. He was the son of Leopold Pfaundler.
In 1890 he began his medical studies in Innsbruck with anatomist Wilhelm Roux (1850-1924). Shortly afterwards he transferred to the University of Graz, where he was influenced by neurologist Gabriel Anton (1858-1933), gynecologist Alfons von Rosthorn (1857-1909), histologist Alexander Rollett (1834-1903), internist Friedrich Kraus (1858-1936) and pediatrician Theodor Escherich (1857-1911), who was also his brother-in-law. After receiving his doctorate he became an assistant to Franz Hofmeister (1850-1922 at Strassburg. He was habilitated for pediatrics in 1900 at Graz, becoming an associate professor and director of its children’s clinic two years later. In 1906 he was appointed director of the university children's hospital in Munich. He would remain in Munich for the remainder of his career.
Pfaundler made contributions in all facets of pediatric medicine. He was particularly interested in the diathetic (hereditary and/or biological predisposition to a disorder) aspects of disease. Another focus involved "social pediatrics", stressing the importance of nursing, education, hygiene and psychological concerns when dealing with children. In his later research he was concerned with issues such as genetics and natural selection.
