How well do we understand our oceans and the marine life they contain? The year Frederick William True (1858-1914) started as a clerk with the United States Fisheries Commission, Germany was beginning to talk about hosting an international fisheries exposition. True was put in charge of the United States exhibit. Two years later at the 1880 Berlin Fisheries Exposition, the Emperor of Germany awarded first prize to the U.S. Fisheries Commission for the variety and completeness of its display. Frederick W. True continued his research on marine mammals and their fossils as he took on curatorial responsibilities at the Smithsonian. These field books, correspondence and journals come from his personal papers held by the Smithsonian Institution Archives.
