Who adopted the dress blue uniform?

The dress blue uniform is a distinctive and iconic representation of the United States Marine Corps, which was officially adopted during the administration of Secretary of War James McHenry. McHenry's influence in the late 18th century was significant as he oversaw the military's organization and uniform standards during a formative period for the Marine Corps.

The adoption of the dress blue uniform reflects a desire to create a cohesive and recognizable image for Marines, particularly as military uniforms evolved to both symbolize a professional military force and foster unit pride. This particular design has since become a hallmark of Marine identity, recognized for its sharp appearance and historical significance.

It's important to know that while General Pate, Archibald Henderson, and Lieutenant Colonel John H. Glenn made noteworthy contributions to the Marine Corps in different capacities, they were not responsible for the adoption of the dress blue uniform. General Pate served as a Commandant, Henderson had a significant long-term influence on the Corps' development, and Glenn was notable for his contributions as an aviator and later as a senator, but none were directly involved in the uniform's adoption like Secretary McHenry was during the early years of the Marine Corps.
