SLIC was mostly written primarily by Jeremy McCormick at SLAC with contributions from Ron Cassell. The code to convert Geant4 runtime objects into LCIO MCParticles was based on parts of Ron's lcsim package, and he is the maintainer. Ron Cassell (SLAC) has also contributed a lot of SLIC code as well as ideas, testing, and debugging help. Other help and ideas have come from Norman Graf (SLAC), Tony Johnson (SLAC), Joe Proulx (University of Colorado), and Guilherme Lima (NIU/NICADD), among others.
