Prosper(Submitted on February 22, 2024, by James Hulse of Medina, Texas.)L'Orange was born on February 1, 1876 in Beirut, in what was then the Ottoman Empire. His father, Dr., who came from a French Huguenot family, Rudolf Heinrich L'Orange is chief physician at Beirut's Johanniter Hospital. When Prosper was 12 years old, his parents sent him to live with relatives in Königsberg. He attended secondary school there and completed his high school diploma. He was interested in engines from an early age. In October 1896 he began studying mechanical engineering at the TH Berlin-Charlottenburg and passed his diploma examination with distinction in the summer of 1900. In the same year he took up an assistant position at the thermal engineering laboratory at the TH Berlin, where he researched refrigeration machines and married Hedwig Eisendick. After completing his one-year military service in Königsberg, he took up his first job in Danzig in 1902, where his eldest son Rudolf was born that same year. In 1903, L'Orange moved to the Princely Stolberg Ironworks Office in Ilsenburg. Here, in the Harz Mountains, the second eldest son Harro was born.Photographed By James Hulse, February 20, 20242.
