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 Geyser
Albert Geyser was born to Maria Johanna Albertina ("Nina") Lamprecht and Petrus Geyser on 10 February 1918 on a farm near Naboomspruit, Transvaal province (now the town of Mookgophong in the Limpopo Province). Petrus and Maria had three children, including Albert's brother, Hendrik Johannes Geyser. The Geyser progenitor had immigrated to South Africa in 1725, and Albert's great-grandfather and grandfather had been among the founding members of the NHK.
Albert Geyser attended primary school in Ermelo, and matriculated from the Hoërskool (High School) Ermelo in 1935. With his brother, Hendrik, he was admitted to the University of Pretoria, with both intending to become ministers in the Nederduitsch Hervormde Kerk (NHK). Albert earned his BA degree in Greek and Latin "cum laude" in 1938, followed by a BD in 1940. As denominational regulations required a minimum age of 23 years for appointment as a minister, Geyser worked in Cape Town until he became eligible in 1941. He was then invited to serve the congregations at Heilbron and at Parys in the Free State, where he was ordained and ministered from 1941 to 1943.
