Who was responsible for adopting the eagle, globe and anchor as the Marine Corps' emblem?

The adoption of the eagle, globe, and anchor as the official emblem of the Marine Corps is attributed to Jacob Zeilin, who served as the 7th Commandant of the Marine Corps. In 1868, he authorized the emblem to symbolize the United States Marine Corps' role as a maritime force, representing the globe, which signifies their global reach and ability to operate anywhere; the eagle, which embodies the strength and authority of the United States; and the anchor, a nod to their naval heritage and amphibious capabilities.

Jacob Zeilin's decision to adopt this emblem was integral in unifying the identity of the Marine Corps and solidifying its distinct place within the U.S. military. The emblem has since become one of the most recognizable symbols associated with the Marine Corps, highlighting its values and tradition.

The other individuals listed either held different roles or did not have a direct impact on the official adoption of the emblem, making Zeilin's contribution unique and historically significant.
