Von Braun helped establish and promote the National Space Institute, a precursor of the present-day National Space Society, in 1975, and became its first president and chairman. In 1976, he became scientific consultant to Lutz Kayser, the CEO of OTRAG, and a member of the Daimler-Benz board of directors. However, his deteriorating health forced him to retire from Fairchild on 31 December 1976. When the 1975 National Medal of Science was awarded to him in early 1977, he was hospitalized, and unable to attend the White House ceremony.
