The Aleut region has the longest history of anthropological and archaeological investigations in all of Alaska. Although predating formal anthropological studies, the extensive ethnographic account by the Russian Orthodox priest Ivan Veniaminov in the early 1800s laid a solid foundation for scientific archaeological and anthropological investigations over the next 100 years, including those by William Healy Dall in the 1870s, Waldemar Jochelson from 1909 to 1910, and Aleš Hrdlička in the 1930s. Following World War II, research continued, and the evolving political picture in Alaska gave Aleut people increasing influence and control over such efforts.
