SAN ANTONIO — Merlin German, a Marine sergeant who became a symbol of resilience as he strove to recover from a roadside bomb blast in Iraq that blanketed 97 percent of his body with burns, has died. He was 22.

German died April 11 at Brooke Army Medical Center, where he was continuing treatment for the injuries he suffered in combat on Feb. 22, 2005, the Pentagon said Thursday.

He was dubbed the “Miracle Man” for his determination in facing his wounds, which cost him his fingers and rippled his face with scars. He endured more than 40 surgeries, spent 17 months in a hospital and had to learn to walk again.

Meanwhile, he started a charity, Merlin’s Miracles, to aid child burn victims, and considered college and a career.
