Walther-Peer Fellgiebel (7 May 1918 – 14 October 2001) was a German officer in the Wehrmacht, serving during World War II and a recipient of the Knight's Cross of the Iron Cross, awarded by Nazi Germany to recognise extreme battlefield bravery or successful military leadership. His father was the General Erich Fellgiebel, who as a conspirator of the 20 July plot was sentenced to death and executed on 4 September 1944.
He joined the Association of Knight's Cross Recipients (AKCR) in 1954 and as of 1961 served on the board of directors. He became head of the order commission of the AKCR in 1970, a position he held until 1985. From this work evolved the book Die Träger des Ritterkreuzes des Eisernen Kreuzes, 1939–1945 (The bearers of the Knight's Cross of the Iron Cross 1939–1945). For many years this book was considered a reference work on this topic. Fellgiebel himself indicated that the book is not official. The deteriorating situation of Nazi Germany during the final days of World War II left a number of nominations incomplete and pending in various stages of the approval process; loss of evidence of the presentation was also an issue in the verification process. In some of these instances the AKCR later accepted and listed holders of the Knight's Cross with questionable evidence. Author Veit Scherzer analyzed the German Federal Archives and found discrepancies in 193 instances of the original 7,322 listings by Fellgiebel (false acceptance rate of 7000260000000000000♠2.6%). Fellgiebel's work was translated into English in 2003 as Elite of the Third Reich: the Recipients of the Knight's Cross of the Iron Cross, 1939-45.
