wlopods would also have been named for him. Since his 
death, however, a fine specimen from the Ordovician of 
Baffin Island will honor him in this manner. 
It should also be noted, in the realm of invertebrate 
paleontology, that at least a half dozen of the Special 
Papers and two of the forthcoming Memoirs of the Geo- 
logical Society of America carry acknowledgment. to 
Frederick Thompson for financial assistance during their

graph recently published by the Museé du Congo Belge 
and for more than a dozen papers in the Journal of 
Paleontology. 
In addition to his indefatigable collecting, both of fos-

with workers in widely scattered institutions attest to his 
restless striving to make paleontology a more dynamic 
field of intellectual interest and activity. In many ways 
he was more successful in these efforts than were his pro- 
fessional (and scientific) colleagues. 
Although the writer personally knew Fred Thompson 
only during the last six years of his life, the memory of 
the man will stand, not only on his scientific contribu- 
tions, but on his unforgettable personality as well. His 
interest in people partook both of their foibles and their 
serious endeavors and he was always ready with an anec- 
dote in either vein. This made him a delightful com-

his later years, Fred’s energy and cheerful persistence in
