This short paper outlines the emergence and achievements of the Science Education Research Unit at the University of Waikato over the period 1979-1985 under the leadership of the late Dr. Roger Osborne. Following his attendance at the ASERA meeting in Wagga Wagga in 1977, Roger Osborne rapidly built up a very productive team, which he led until his death in 1985. His legacy is tentatively evaluated. In conclusion, the cultural context in which this work took place is sketched.
