Here are links to two different articles that explain the history of atomic masses. In the Wikipedia article, just skip down to the "History" section:
http://science.jrank.org/pages/634/Atomic-Weight-History.html
https://en.wikipedia.org/wiki/Atomic_mass
An atomic mass unit is defined as 1/12 the mass of a Carbon-12 atom. The Wikipedia article on atomic mass has more details.
