As tributes and memories poured in following the sudden death of Belfer Center Director Ash Carter on October 24, it became increasingly clear that his legacy of teaching and serving will live on through the students he taught, colleagues he mentored and worked alongside, and the many individuals whose lives he touched during his work in and out of government. 

Here, through the words of students, colleagues, government officials, and others, we share something of the incredible impact of this extraordinary man known as “Professor Carter,” “Secretary Carter,” “Sir,” and just “Ash.” 

Ambassador George Krol (ret.) recounts Ash Carter's unique qualities and the seminal role he played in developing U.S. policy toward the newly independent republics of the former Soviet Union in the mid-1990's.  "He left a lasting impression on all of us," Amb. Kool writes, "including, I contend, in many of the republics of the former USSR."

I never thanked him. But I know I will never again miss the opportunity to thank my heroes.

It is with deep and profound sorrow that I write to inform you that our colleague, teacher, and friend Ash Carter passed away yesterday evening after suffering a heart attack.
