The Department of Navy called one day and said they needed live animal traps for experimental purposes to study diseases transmitted by rodents in the South Pacific Islands. They'd heard about Sherman traps, even though he'd never made them commercially... his graduate students were those benefiting from them.

My father designed the machinery for making traps with help from my grand-father in the 20's, and made his own machines to build them. They were kept in our garage, a very orderly place with a lathe, a drill press, power saw, and many other tools. In addition to my two pet squirrels and one opossum. There was never room for a car. This was kept in the carport which he constructed for this purpose.

Since 1955 H.B. Sherman Traps have been the worldwide standard in live animal traps, helping facilitate small mammal research in a safe, environmentally friendly way. The traps are used to catch a wide variety of animals including shrews, voles, mice, rats, chipmunks, flying squirrels, ground squirrels, and so much more. The most common reported uses are population studies, collection, teaching and ecological or environmental impact studies. Others use them for mark and release programs, summer nature camps, or simply personal observation and pleasure. They are even used to promote fossil research and relocation.
