X-rays were discovered by Wilhelm Roentgen in 1895. Soon after their discovery Roentgen used x-rays to image the bones in a human hand. The x-rays transmitted through the hand (phenomenon 1) were recorded on photographic film. The bones or other dense objects absorb x-rays more than do soft tissues or less dense materials (phenomenon 2). This method of imaging the internal stmcture of an object is known as x-ray radiography.

The first Nobel prizes were awarded in 1901 to Wilhelm K, Roentgen (discovery of X-rays in 1895), J.H. van t Hoff (chemical thermodynamics and osmodc pressure), and E.A. von Behring (diphtheria antitoxin). Listings of scores of Nobel prizes awarded over a century of progress can be found... 

In 1895 X-rays were discovered by Wilhelm Roentgen. At first Henry Becquerel (1852 - 1908) thought that X-rays were related to his studies and he imagined that fluorescent materials would produce X-rays. He then designed experiments to prove this.
