The Wald Memorial Lectures honor Professor Abraham Wald. The Wald Lecturer gives two, three or four one-hour talks on one subject. This gives sufficient time to develop material in some detail and make it accessible to nonspecialists.
The Blackwell Lecture should reflect one of Blackwell’s many interests in probability, statistics and/or the allied fields of game theory and information theory and could serve to bring these fields closer to statistics and vice versa. An endowment was set up to cover the cost of travel and a plaque for the lecturer.
The Le Cam Lecturer should be an individual whose contributions have been or promise to be fundamental to the development of mathematical statistics or probability. An endowment was set up by friends of Le Cam to cover the cost of travel and a plaque for the lecturer.
The Neyman Lecture ordinarily will emphasize the interactions between statistical theory and scientific research.
The Rietz Lectures are named after the first President of the Institute of Mathematical Statistics, Professor Henry L. Rietz. The Lectures are intended to be of broad interest and serve to clarify the relationship of statistical methodology and analysis to other fields.
The Committee on Special Lectures invites eight individuals to deliver Medallion Lectures annually. Medallion Lectures are distinct from Invited Papers, which are chosen by the various Program Committees for specific meetings. Each Medallion Lecturer will receive a Medallion in a brief ceremony preceding the lecture. For more information, see here: https://www.imstat.org/handbook/committees.html
