List of Knight's Cross of the Iron Cross recipients (I)

The Knight's Cross of the Iron Cross (Ritterkreuz des Eisernen Kreuzes) and its variants were the highest awards in the military of the Third Reich during World War II. The Knight's Cross of the Iron Cross was awarded for a wide range of reasons and across all ranks, from a senior commander for skilled leadership of his troops in battle to a low-ranking soldier for a single act of extreme gallantry. A total of 7,323 awards were made between its first presentation on 30 September 1939 and its last bestowal on 17 June 1945. This number is based on the analysis and acceptance of the order commission of the Association of Knight's Cross Recipients (AKCR). Presentations were made to members of the three military branches of the Wehrmacht—the Heer (Army), Kriegsmarine (Navy) and Luftwaffe (Air force)—as well as the Waffen-SS, the Reichsarbeitsdienst (RAD) and the Volkssturm. There were also 43 recipients in the military forces of allies of the Third Reich.

These 7,323 recipients are listed in the 1986 edition of Walther-Peer Fellgiebel's book, Die Träger des Ritterkreuzes des Eisernen Kreuzes 1939–1945 – Die Inhaber der höchsten Auszeichnung des Zweiten Weltkrieges aller Wehrmachtsteile — The Bearers of the Knight's Cross of the Iron Cross 1939–1945 — The Owners of the Highest Award of the Second World War. In 1996 a second edition of this book was published with an addendum delisting 11 of these original 7,323 recipients. Author and historian Veit Scherzer has cast doubt on a further 193 of these listings. The majority of the disputed recipients had received the award in 1945, when the deteriorating situation of the Third Reich during the final days of World War II left a number of nominations incomplete and pending in various stages of the approval process. Listed here are the 26 Knight's Cross recipients whose last names start with "I", ordered alphabetically. The rank listed is the recipient's rank at the time the Knight's Cross was awarded.

Background
The Knight's Cross of the Iron Cross and its higher grades were based on four separate enactments. The first enactment Reichsgesetzblatt I S. 1573 of 1 September 1939 instituted the Iron Cross (Eisernes Kreuz) and the Knight's Cross of the Iron Cross. As the war progressed, some of the recipients distinguished themselves further and a higher grade, the Oak Leaves to Knight's Cross of the Iron Cross, was instituted. The Oak Leaves, as they were commonly referred to, were based on the enactment Reichsgesetzblatt I S. 849 of 3 June 1940. In 1941, two higher grades of the Knight's Cross were instituted. The enactment Reichsgesetzblatt I S. 613 of 28 September 1941 introduced the Knight's Cross of the Iron Cross with Oak Leaves and Swords (Ritterkreuz des Eisernen Kreuzes mit Eichenlaub und Schwertern) and the Knight's Cross of the Iron Cross with Oak Leaves, Swords and Diamonds (Ritterkreuz des Eisernen Kreuzes mit Eichenlaub, Schwertern und Brillanten). At the end of 1944 the final grade, the Knight's Cross of the Iron Cross with Golden Oak Leaves, Swords, and Diamonds (Ritterkreuz des Eisernen Kreuzes mit goldenem Eichenlaub, Schwertern und Brillanten), based on the enactment Reichsgesetzblatt 1945 I S. 11 of 29 December 1944, became the final variant of the Knight's Cross authorized.

Recipients
The Oberkommando der Wehrmacht (Supreme Command of the Armed Forces) kept separate Knight's Cross lists for the Heer (Army), Kriegsmarine (Navy), Luftwaffe (Air force) and Waffen-SS. Within each of these lists a unique sequential number was assigned to each recipient. The same numbering paradigm was applied to the higher grades of the Knight's Cross, one list per grade. Of the 26 awards made to servicemen whose last name starts with "I", one was later awarded the Knight's Cross of the Iron Cross with Oak Leaves and Swords and one presentation was made posthumously. Heer members received 16 of the medals, one went to the Kriegsmarine, and nine to the Luftwaffe.
