Dr. L. 0. Howard was born at Rockford, Illinois, 1857, and is 
still living. The year following his graduation from college, he 
became assistant entomologist in the Department of Agriculture 
at Washington. He remained in this official position until 1894, 
at which time he was made chief of the Bureau of Entomology. 
This position he still holds. He prepared definitions in entomology 
for the Century and Standard dictionaries. He is the author of 
Mosquitoes — How they Live; The Insect Book; The House-Fly; 
and many government publications. For many years he has acted 
as the permanent secretary for the American Association for the 
Advancement of Science, the largest body of scientific workers 
in America. 
Dr. Howard has devoted his main energies for the past forty 
years to applying the technical discoveries in entomology to 
human welfare.
