Everyone at Walter Reed Army Medical Center called her Peanut long before they called her Colonel.
She'd carried that nickname since she was a kid trailing her older brother and sister around Fort Riley in 1965, given to her by her dad's Army buddy, a platoon sergeant named Omer. Her father was a combat medic. She grew up watching him serve, and she decided early on she wanted to do the same.
She graduated Judson High School in San Antonio in 1979. Five years later, in 1984, she earned her commission through ROTC at the University of Nevada, Las Vegas, where she'd also played guard on the women's basketball team. By 1992, she'd added a Master's in Health Services Administration from Webster University. Seventeen years of service later, she was one of the Army's most respected personnel officers.
In July 2001, at Walter Reed's Building One, more than 60 friends and colleagues gathered to watch her get pinned Lieutenant Colonel. Word spread through the halls, and the crowd swelled past 100 people. She insisted the real star of the day was the strawberry cake she'd ordered. "You've got to have a great cake when you're promoted," she told a friend, "because that's all that anyone will remember."
She was wrong about that. But not about much else.
That same promotion sent her to a new post: Medical Personnel Officer in the Office of the Army Surgeon General, working as Deputy Chief of Staff for Personnel — at the Pentagon. She was 40 years old, and by every account, at the top of her game.
She'd only been at her new desk for about five weeks.
On the morning of September 11, 2001, Lieutenant Colonel Karen J. Wagner was at that desk when a hijacked plane struck the building. She did not run. Witness accounts say she stayed to help others get out first.
She never made it out herself.
She was one of 184 people who lost their lives at the Pentagon that day. The Army posthumously awarded her the Legion of Merit, the Order of Military Medical Merit, and the Purple Heart. She was laid to rest with full military honors at Fort Sam Houston National Cemetery, not far from where she grew up.
In 2003, Walter Reed named its sports center after her. Fort Sam Houston named the headquarters of its 32nd Medical Brigade "Wagner Hall." Her hometown of San Antonio built an entire high school and named it after her — Karen Wagner High School — where JROTC cadets still study her story today.
She used to joke about her post-Army plans: maybe teaching overseas, maybe hosting a cooking show with her sister, since baking was her thing. She never got the chance to find out which one she would've chosen.
But two decades later, teachers at the school bearing her name say they still look up at her photo every morning before the day starts. Not because of how she died. Because of how she chose to spend the last minutes she had.
That's the part worth remembering.
