I am honoured, deeply honoured, that so distinguished a group has assembled to acknowledge the signifi- cance of the work of my Melbourne flotation research laboratory, to review progress since Principles of Flotation (Wark, 1938) was published, to highlight the present state of knowledge, and to point the way for future research. The flotation research which began in 1929 was sponsored by a group of mining companies2 at the instigation of Harry Hey of the Electrolytic Zinc Company of Australasia Limited. There were never more than three of us work- ing in rather cramped conditions in a laboratory made available by the Department of Chemistry at the Uni- versity of Melbourne, but what we lacked in space was more than offset by a freedom unparalleled in indus- trial research in Australia at that time. I pay special tribute to my first colleague, Alwyn Cox; to my wife who worked with us for several years; and to Keith Sutherland who followed Cox in 1936. They were my sole colleagues up to 1938 when Principles of Flo- tation (Wark, 1938) was published.
