RasMol:
From 1992 to 1998,
RasMol (by Roger A. Sayle)
was the best general-purpose free software for visualizing
3D structures of macromolecules on personal computers.
In 1995, only a few years after the birth of the Internet, with the blessing of
Roger Sayle, Eric Martz created the first website for RasMol.
It was enormously popular, and the RasMol program was downloaded tens of thousands of times
from that website.
Its biggest limitation was that a complicated, extensive
command language had to be learned to use it effectively.
This greatly limited the ability of college faculty or their students
to use it effectively.
That became apparent when Eric Martz attempted to teach college faculty in
the Northeastern USA to use Rasmol, supported by a grant from the National Science
Foundation Division of Undergraduate Education funded in February, 1997.
It was out of this frustration that Eric Martz conceived
Protein Explorer.
Protein Explorer, created by Eric Martz,
was first available in October, 1998, and Eric continued to develop it
through the version documented below, version 2.81, released in 2007.
Protein Explorer won the international
2003 Merlot Exemplary Classics Award for Biology.
The award stated
"The Protein Explorer has revolutionized the teaching of biology at a molecular level."
Protein Explorer made the power of Chime (see below) accessible by providing buttons and forms
so that users did not need to learn any Chime command language.
