Between 1935 and 1942, a total of 130 men, aged seventeen to twenty-four, mostly of indigenous Hawaiian heritage, colonized Howland, Baker, and Jarvis Islands for the United States, in rotation, over the course of twenty-six expeditions. As part of the American Equatorial Islands Colonization Project (AEICP), they compiled meteorological data, observed and recorded the natural life of their surroundings, collected specimens for the Bishop Museum in Honolulu, mapped the islands, and built a landing strip on Howland for Amelia Earhart. In doing so, they confirmed U.S. possession of the islands, its imperial and military power in the Pacific, and helped establish aviation routes in the South Seas, all of which assisted American efforts during World War II. At the time, the AEICP colonists did not know the role they were playing in this larger project. While some thought they were recruited as part of the museum's scientific research, others were under the impression that they were stationed on the islands to contribute to commercial air travel. This article will examine the AEICP's scientific framework, how it was deployed as a pretext for larger military and imperial goals, and the ways in which it is an example of the hidden or invisible labor of science that dominated the interwar years, World War II, and the Cold War era. Moreover, it will also expose the underlying scientific racist hierarchy of the AEICP wherein the colonists themselves were classified as "types" and "specimens" to be studied.
