Gatewood Sanders Lincoln (August 5, 1875 – October 15, 1957) was a United States Navy officer who served as the governor of American Samoa.

He commanded a supply ship during World War I and was an instructor at the United States Naval Academy, serving as Department Head of the College of Electrical Engineering and Physics.

[12] He separated the responsibilities of the Chief Justice and the Attorney General, and he started a Samoan-led judicial commission to deal with matters involving land ownership, thereby granting the Samoan people more autonomy.

By 1927, the American Samoa Fono's attempt to limit educational reforms highlighted two major concerns: the disruptive effects of new knowledge and behaviors on students, and the diminishing respect for Samoan culture due to the influence of foreign teachers.

This shift gained momentum in 1933 with significant changes introduced by a committee of educators from the University of Hawaiʻi, funded by the Barstow Foundation, who further adapted the curriculum to better serve local needs.

[15] In its final years, the Mau movement in American Sāmoa assumed a watchdog role, diligently scrutinizing the actions of the U.S. Navy.
