Since 1940, members of the BSR have elected a President of the society, drawn from a broad range of rheological backgrounds and interests. Each president serves for a period of two years, and more recently they have been invited to sit on council as president-elect and immediate past president. Brief biographical details of each former president can be found below.
The background research for this page was undertaken by P. Rigby, Aberystwyth University.
