Owen O'Brien
O'Brien supported the merger of the various print unions. In 1976, NATSOPA passed a motion to this effect, and O'Brien forged a close working relationship with Bill Keys of the Society of Graphical and Allied Trades (SOGAT). In 1982, NATSOPA merged with SOGAT, forming SOGAT '82; O'Brien and Keys served as joint general secretaries of the new union until O'Brien retired at the end of 1983. O'Brien died while on holiday in Portugal, four years later.
