Biography
Elster and Hans Friedrich Geitel, the son of a Forstmeister who had moved to Blankenburg with his family in 1861, grew up in the same neighborhood and attended school and high school together. The personal friendship was deepened by the shared interest in the natural sciences during their years at university in Heidelberg and Berlin. After they received their teaching certification in Brunswick, they went their separate ways for a short time. In 1881 they were working together at the Great School in Wolfenbüttel and used their leisure for experimental research. There Karl Bergwitz (1875–1958) was among their students.
Elster was awarded a honorary doctorate (1915) along with Geitel at the Braunschweig University of Technology. In 1919, Julius Elster was diagnosed with a disease (diabetes mellitus). In April 1920, the Privy Councilor Julius Elster died in Bad Harzburg during a spa stay.
