  The idea of atoms is old but X-rays provided the first probe into the
physical atom. Photographs of X-ray scattering from crystals -Laue spots- were
the first visual proof for the physical existence of atoms arranged in a
perfect geometric pattern. Thereby conclusively established the stability and
physical reality of atoms. The Braggs developed Laue technique to study atoms.
Moseley applied (Bragg) X-ray spectroscopy to determine the nuclear charge
number of Rutherford atom. We argue that Bohr also at Manchester and
contemporary of Moseley likely was inspired by Laue discovery to get busy with
the mechanics of the nuclear atom. Roentgens discovery was awarded the first
Nobel prize ever in 1901, Laue was honored in 1914, the Braggs in 1915, making
Lawrence Bragg then at 25 the youngest ever. Eleven of the cited authors (Bohr
himself included) in the trilogy (but not Nicholson the most cited), were later
recognized by ten Noble prize awards, seven Laureates in physics and four in
chemistry. The ensuing synergy between science and Nobel honors has been
critical.
