Wilhelm Conrad Röntgen was born on March 27, 1845, at Lennep in the Lower Rhine Province of Germany, as the only child of Friedrich Conrad Röntgen and Charlotte Constanze. His family relocated to Apeldoorn in The Netherlands when he was three years old, and he attended the Institute of Martinus Herman van Doorn, a boarding school. Röntgen loved nature and enjoyed exploring the vast land and forests. He was highly skilled at devising mechanical devices, which he retained throughout his life. In 1862, he enrolled in a technical school in Utrecht, where he was wrongly expelled for producing a caricature of one of the lecturers, which was actually done by someone else.
