FLOWTRAN was designed to allow industrial chemists to run simulations of various chemical reactions. Although originally intended for industrial use it became popular in the academic world as well. As the demand for increasingly sophisticated analyses grew FLOWTRAN was supplanted by HYSIM another Monsanto product. Robert H. Cavitt, whose papers are interspersed throughout the collection, was instrumental in the development of FlowTran, as it was he who advocated the building block architecture on which the program was built. Edward Rosen the donor of this collection was a Monsanto executive. He also ran their program for rehabilitating injured employees, which aided Cavitt in his recovery from a massive cerebral hemorrhage.
