WILLIAM MORTON WHEELER MEMORIAL ISSUE 
March 19, 1965, is the centennial of the birth of William Morton 
Wheeler, Professor of Entomology at Harvard University from 
1908-1937 and an active member of the Cambridge Entomological 
Club for that period. The Editorial Board of Psyche has designated 
the present number of the journal as the William Morton Wheeler 
Memorial Issue and has arranged to include in it articles on ants 
and other social or subsocial insects. No attempt has been made to 
obtain contributions by all of Professor Wheeler’s former students; 
most of the papers published here were already in the editorial office 
before plans for the memorial issue were definitely made. Included are 
contributions by three generations of students whose interest in social 
insects can clearly be traced to Professor Wheeler. We are indebted 
to Professor W. L. Brown, Jr., of Cornell University for the use 
of the accompanying photograph, which was taken about five years 
after Professor Wheeler was appointed at Harvard University. 
A biographical account of Professor Wheeler, with a complete 
list of his publications, was published in Psyche, Volume 44, No. 3., 
1937.
