Wilhelm Conrad Röntgen
In 1901 the very first Nobel Prize for Physics was awarded to Röntgen for the discovery of X-rays. A year later his parents died and Röntgen inherited two million marks. He and his wife were now both rich and famous. He spent much time traveling, with little devotion to further scientific research. Before he already won the Rumford Medal, the Matteucci Medal and the Elliott Cresson Medal.
