good ol Issac not only divided light but also worked on
the understanding
of simple machines. The list is numerous, just go here:

I'm not sure, but didn't Newton discoverd the breaking of
light by means
of
a prism?

A good place to start is to read Newton's book
_Opticks_. The easiest edition to find is the 1952 Dover
reprint of The Bell edition of 1931, in turn based on the
forth (1730) edition. Newton's original book was published
in 1704.
The Dover book was reprinted several times in later
years. The ISBN is: 486-60205-2 Its even possible that a new
edition has been printed (I have not looked) but it should
not be too difficult to find used.
This reprint has, in addition to the material in the
1931 edition it was taken from, a forward by Albert Einstein
and an analytical table of contents.
Einstein has a cogent explanation of the conflict of the
two ideas of the nature of light, the partical theory and
the wave theory, and why Newton's evident ability to accept
both simutaneously was the cause of great controversey at
the time. While Newton did not predict the work of Einstein
he appears to have realized something of the sort was
necessary to explain the phenomon of light.
Newton describes the use of prisms to separate light
into its component colors in Book 1, Part 1.
The book is quite readable and has surprisingly little
mathematics in it. Definitely understandable by a
non-specialist.
A note: Helge Neried is a Ph.D. in optics (he will
correct me if I am wrong about the details) and is
thoroughly knowledgeable about optics.
