Brigadier General Margaret A. Brewer (July 1, 1930 – January 2, 2013) was the first woman in the United States Marine Corps to reach general officer rank.^[2]

Brewer was born in Durand, Michigan, on July 1, 1930,^[1] to Maurice and Anne Brewer. Her parents divorced early in her life. Her ancestors on her fathers' side were early settlers of Michigan and are buried near Bishop Airport in Flint, Michigan. Brewer received her primary education in Michigan, attending Ryno School in Clayton Township, Genesee County in 1936.^[3] She later graduated from the Catholic High School in Baltimore, Maryland, prior to entering the University of Michigan at Ann Arbor.^[1] She received a bachelor's degree in geography in 1952,^[1] and was a member of Zeta Tau Alpha sorority.

She was then transferred to Brooklyn, New York, for a two-year tour as Inspector-Instructor of a Women Marine Reserve unit.^[4]

From September 1955 until June 1958, then Captain^{[citation needed]} Brewer served successively as Commanding Officer of the Women Marine companies at Norfolk, Virginia, and Marine Corps Base Camp Lejeune, North Carolina.^[4] During the 18 months following,^{[citation needed]} she was a platoon commander for woman officer candidates at Marine Corps Base Quantico, Virginia, during summer training sessions, and for the balance of the time, a woman officer selection officer with headquarters in Lexington, Kentucky.^[4]

Transferred to Marine Corps Base Camp Pendleton, California, in November 1959, for duty with the Commissioned Officers Mess (Open), Brewer was promoted to major in September 1961 and in April 1963 returned to Quantico to serve as executive officer and later as commanding officer of the Woman Officer School.^{[citation needed]} By 1966, she was the Public Affairs Officer for the 6th Marine Corps District, Atlanta, Georgia as lieutenant colonel.^[4]
