Walter Haeussermann (also spelled Häussermann; March 2, 1914 – December 8, 2010)[1] was a German-American aerospace engineer and member of the "von Braun rocket group", both at Peenemünde and later at Marshall Space Flight Center, where he was the director of the guidance and control laboratory.[2] He was awarded the Decoration for Exceptional Civilian Service in 1959 for his contributions to the US rocket program.[2]

Haeussermann was born in Germany shortly before the beginning of World War I. He eventually matriculated at the Darmstadt University of Technology, where he earned a doctorate in physics.[2] He was drafted into the German army for World War II and taken to the rocket development center at Peenemünde on December 1, 1939.[3] In a 2008 interview, he recalled seeing a rocket engine test upon his arrival there, saying, "I was flabbergasted, because on the first day I was shown a rocket test ... I was astonished that something like this was already existing." Asked about meeting von Braun, he enthusiastically replied, "I met him the second day. I was very interested about him." He worked on the V-2 guidance and simulations by means of analog computers.[1]

He stayed at Peenemünde 3 years, then returned to Darmstadt where he worked for Kreiselgeraete and Siemens to develop a gyroscopic guidance platform. After the war, he was invited to join von Braun's team in Fort Bliss, Texas, but initially declined because his wife was ill.[1][3]

Helmut Hölzer and Ernst Steinhoff accepted the Operation Paperclip invitation to the United States, traveled there in late 1945, and maintained contact with Haeussermann. Haeussermann came to the United States in 1947 to rejoin von Braun's team, working on ballistic missile guidance and control engineering at Fort Bliss. In 1951, the group moved to Redstone Arsenal.[1]

In 1954, Haeussermann became a naturalized US citizen.[1] At that time he was the director of the Guidance and Control Laboratory and head of the Astrionics Division of what is now Marshall Space Flight Center.

NASA was formed in 1958, and Haeussermann was on the initial roster. There, he led electrical, computer systems, guidance, and navigation systems for the Saturn V. He took his responsibility for the astronauts safe transport seriously. He said, "I refused any congratulation before Apollo 11 astronauts were safely back. Of course, we were very proud."[1]

His contributions to the space program were recognized with the Decoration for Exceptional Civilian Service in 1959.

Haeussermann remained an enthusiastic supporter of the space program and attended reunions and public events regularly until his death.[4]

Work in guidance and controlEdit

Haeussermann's main area of work was in automatic guidance and control for missiles. For example, he was instrumental in the design of the Saturn V system.[5] He also conducted research more broadly, for instance in 3-axis attitude control[6] and the use of Hall devices in aerospace control devices.[7] In his late career, he examined control issues related to experiments on board the Space Shuttle.[8]

Arthur RudolphEdit

Haeussermann was a colleague of Arthur Rudolph, who in the 1980s had become the subject of harassment from the OSI and Eli Rosenbaum over alleged Nazi war crimes. Haeussermann was at one time part of Rudolph's defense team tasked with proving his innocence.[9]
