citement of this continuing adventure in his wondrous after-dinner 
anecdotes of field trips around the world. A common story has it 
that Mann’s faculty sponsor at Harvard, William Morton Wheeler, 
was at first keenly disappointed when he abandoned a full-time career 
as entomologist for zoo-keeping but soon became completely recon- 
ciled by his former student’s obvious genius in the latter role. At the 
National Zoological Park, Mann was enormously successful. He de- 
veloped humane, new techniques in zoo culture and was responsible 
for the introduction of many new animals to zoo life. He was re- 
nowned for the wit and eloquence with which he sought, and success- 
fully obtained, the congressional appropriations needed to expand his 
zoo. His unfailing hospitality was extended to persons from all walks 
of life, and he had many close friends and an army of warm personal 
admirers. “Small in stature, puckish, bright-eyed and almost formally 
unkempt, Dr. Mann possessed a gentle wit which he used sparingly 
in public — lest it be considered unseemly in a scientist of his ac- 
knowledged standing. . . He became a familiar figure to thousands 
of Zoo patrons who brought away with them the charming memory 
of intimate little chats he was never too busy to hold with the least of 
his visitors.’’* When he died in his Washington home on October IO, 
i960, at the age of seventy-four, the Ant Hill Odyssey perhaps seemed 
to many of his friends no more than a remote chapter in a colorful 
past. Yet it should not be forgotten that his early work produced 
major contributions that have actually gained in value with the pass- 
age of time. 
Mann’s collections of ants and myrmecophiles, which are the most 
significant parts of his general collections, are divided chiefly between 
the Museum of Comparative Zoology and the U. S. National Mu- 
seum. His entomological publications are based mostly on this ma- 
terial, a fact that gives them their exceptional value. Mann’s collec- 
tions, especially those of ants made in the West Indies and South 
Pacific, were unusually thorough. Few men have been able to write 
taxonomic papers on tropical insect faunas with such an intimate first- 
hand knowledge of the ecology and faunal relationships of his study 
material. As a result, his larger monographs have been little improved 
on by later work and will undoubtedly remain primary references for 
years to come. The following bibliography includes as complete a list 
of Mann’s technical entomological publications as could be assembled 
at this time. References to his well-known popular article on ants in 
the National Geographic and to his autobiography are also included.
