J. Paul Morrison, born John Paul Rodker in London, invented Flow-Based Programming (FBP) in the late 1960s while at IBM, introducing a dataflow paradigm that treats applications as networks of reusable black-box processes communicating via information packets. His seminal book, Flow-Based Programming: A New Approach to Application Development, published in 1994 by Van Nostrand Reinhold, detailed this innovative approach influenced by GPSS and unit record equipment. Morrison's work at the Bank of Montreal on the Mech online banking system demonstrated FBP's longevity, with components maintained for decades by non-original developers.
