Study Notes

Wilhelm Conrad Roentgen: Life and Discoveries

Roentgen lost both parents in the early 1880s, with his mother passing in 1880 and father in 1884.
After their deaths, Roentgen and his wife adopted his niece, Josephine Bertha Donges, in 1887.
Conducted experiments using Hittorf-Crookes and Lenard tubes, contributing to the discovery of X-rays.
In 1895, while activating a Ruhmkorff coil, he observed a mysterious fluorescence that led to the identification of X-rays.
His discovery was recognized immediately, leading to international acclaim and pervasive curiosity among scientists.

Academic and Professional Journey

Elected president of Julius Maximilians University of Würzburg for the term 1894-1895.
After the discovery of X-rays, received letters of congratulation from leading scientists worldwide.
Offered a directorial position at the Physical Science Institute, Ludwig Maximilians University of Munich, with a significant promotion and civil service status.
Accepted the new role, albeit with reservations due to the need to separate from his family ties and previous associations.

Educational Background

After graduating, Roentgen remained at the University of Zurich and studied under Dr. August Kundt, a prominent physicist.
Developed theoretical skills under Kundt, leading him to write a dissertation titled "Studies on Gases."
Received his doctorate in philosophy on June 22, 1869, solidifying his foundational expertise in physics.

Context of Discoveries

Utilized a variety of experimental setups, including glass cathode ray tubes and darkened environments to facilitate observations during experiments.
His work laid the groundwork for significant advances in medical imaging and physics, shaping modern diagnostic practices.
