Alfred Bielschowsky (December 11, 1871 – April 5, 1940) was a German ophthalmologist. His specialty was physiology and pathology of the eye, particularly in regards to research of eye movement, space perception and diagnosis of oculomotor anomalies.
Bielschowsky was born in Namslau (Namysłów), Prussian Silesia. After attending the Königliches Katholisches Gymnasium of Glatz (Kłodzko), he studied medicine at the University of Breslau (Wrocław) and at the University of Heidelberg. At Heidelberg he was a student of ophthalmologist Theodor Leber (1840-1917). Afterwards he studied medicine at the University of Berlin, attending the lectures of Karl Ernst Theodor Schweigger (1830-1905) and graduating in 1893. He received his medical license in Leipzig on March 1 of the same year.
Bielschowsky subsequently studied and worked in the eye clinic at the University of Leipzig, receiving his habilitation in 1900 and becoming head physician of the clinic in 1906. While at Leipzig he worked under physiologist Ewald Hering (1834-1918), and with Franz Bruno Hofmann (1869-1926), he conducted studies of fusion and cyclodeviation in superior oblique muscle paresis. In 1912 Bielschowsky attained the chair of ophthalmology at the University of Marburg.
During World War I, Bielschowsky established a hospital ward and Braille instruction for treatment of blinded soldiers. In 1916, along with Carl Strehl (1886-1971), he founded the Verein blinder Akademiker Deutschlands (Association of Blinded Academics of Germany). For his war-time contributions, he was awarded the Iron Cross for War Aid from Paul von Hindenburg and honored with the title of Geheimer Medizinalrat (Privy Medical Counselor) by Wilhelm II, German Emperor.
In 1923 Bielschowsky was appointed chair of ophthalmology at the University of Breslau. While here, he published "Die Lähmungen der Augenmuskeln" (1932), an influential work on eye muscle disturbances.
Because of his Jewish heritage and Nazi persecution, Bielschowsky was fired from his position in 1934, later emigrating to the United States (1936). In 1937 he became head of the Dartmouth Eye Institute at Dartmouth College in Hanover, New Hampshire. However, he died suddenly in 1940. During the same year his "Lectures on motor anomalies" was published.
Though not much history is confirmed about Bielschowsky's family, we do know that there are living generations of the Bielschowsky family. His nephew Wolfgang Albert Bielschowsky (1915-2008) had fled to America during the Holocaust, and at Ellis Island, his name was changed to Fred Biel. Fred married Ingeborg Weber-Biel (1927-2015) and then was drafted to World War II after Ingeborg gave birth to son, George Biel (1949-present). After Fred served in the army, he and Inge had son Frank Biel (1955-present). George married his wife Wendy and had 2 children, Scott and Brad. Scott is now married to Crystal and has a child named Sasha. Frank married Adrienne Duffy in 1988, and had twin daughters in 2000, Ashling and Kaitlin who passed at birth. Then she gave birth to Aidan and Shannon Biel who are twins as well. These are the only known members of the Bielschowsky family in the present.
