Frederick Steven Rosenfeld was born on August 29, 1941 in New York to Eugene and Ethel. When Frederick was quite young, his family moved to Washington D.C., where he grew up and attended school. He served in the US Army, in the 82nd Airborne Division. He first visited Israel when he was 18, and in 1968 returned and decided to stay.
He volunteered on Kibbutz Massada where he was injured when his truck hit a mine. After recovering from his injuries he joined an archeological dig in Ein Bokek, where he met his wife Rachel. They lived in Tel Aviv until 1988, when they moved to Ariel.
On Shabbat, June 17, 1989 Frederick went for a walk in the hills near Ariel. There he met a group of shepherds who took the knife he was carrying and stabbed him to death, hiding his body on the side of the road.
Frederick was buried in Tel Aviv and left behind a wife and a brother.
