It is with considerable sadness that we record the passing of Bill Ellwood on 30 June this year. Bill wrote much of the material for Maths Week each year between 2006 and 2019.
Bill taught for many years in at Burnside High School in Christchurch. He is a past President and life member of the New Zealand Association of Mathematics Teachers and the Canterbury Mathematical Association. Bill co-authored several maths text books during his career and was the writer and editor of the Maths Digest for several years.
NZAMT acknowledges the major contribution that Bill made to Maths Week over many years, and extends deepest sympathy to his family.
