Robert “Bob” Krauss is the Official Historian of the 509th Composite Group. He and his wife, Amelia Krauss, published The 509th Remembered, which profiles the service members of the 509th Composite Group and the events that surrounded the group and its role in dropping the atomic bombs on Hiroshima and Nagasaki.
Krauss became interested in collecting and preserving the history of the 509th in his twenties after reading the book Enola Gay by Max Morgan-Witts. During his research, he met and befriended many of the airmen of the 509th, including Donald Albury, Ray Gallagher, Fred Olivi, Paul Tibbets, George Caron, and others.
Krauss began planning the 509th’s reunions in 2000, and has hosted the gathering for nearly two decades. Over the years, he has collected photographs, correspondence, flight suits, and other artifacts from the members of the 509th.
