Albert Ludwig Sigesmund Neisser
Neisser was born in the Silesian town of Schweidnitz (now Świdnica, in Poland), the son of a well-known Jewish physician, Dr. Moritz Neisser. After he completed the elementary school in Münsterberg, Neisser enrolled in the St. Maria Magdalena School in Breslau (now Wrocław, in Poland). In this school, he was a contemporary of another great name in the history of medicine, Paul Ehrlich. He obtained the Abitur in 1872.
Albert Niemann (tenor)
Born in Erxleben, near Magdeburg, Niemann lost his father (an innkeeper) at an early age and was brought up by his mother, a woman 'of almost unwomanly hardness' who lived to be ninety. He was apprenticed to an engine-maker, but ran away to Dresden to make his own life. He grew up with a Germanic dedication to hunting but also student-like, reading extensively in science, history and philosophy. He was not particularly sociable or tactful, was blunt in speech and often boorish in behaviour.
