SCHWEIKHARD, William G. 77. Beloved husband, father, grandfather, and friend, died Sunday, July 12, 2009, at the UCLA Medical Center in Los Angeles following a brief illness. Bill, as he was known to family and friends, had an illustrious career in the aerospace industry that spanned more than five decades. A co-founder of Kohlman Systems Research, he was associated with or directed numerous aerodynamic, propulsion, and performance flight test and research programs worldwide. A senior scientist for AS&M at NASA Dryden Flight Research Center, he also was a professor of Aerospace Engineering at the University of Kansas, Director of Propulsion and Performance Research at NASA Dryden Flight Research Center and academic technical director of the USAF experimental test pilot school. Most recently he was President of Flitech Inc. Among Bills many awards and honors was the AIAA Octave Chanute Award for lifelong contributions to Flight Testing. Bill also played an instrumental role in the founding of America's space program, developing and teaching the first astronaut training class. In addition to his distinguished career in the aerospace industry, Bill was a heart transplant recipient who often told people that he was very young because he started his second lease on life when he received a heart at the University Hospital of Cincinnati in 1998. Born July 8, 1932, in Hollywood, California, to George and Edna Schweikhard, Bill was a graduate of Fairfax High School. He received a bachelors degree in engineering from the University of California at Los Angeles, and a masters degree in mechanical engineering from the University of Southern California. On July 23, 1955, he married Nebraska native Carol Bridenbaugh, whom he met through church, and they had four children. The Schweikhards lived in Lancaster, California until 1978, when Bill accepted a professor of Aerospace Engineering position at the University of Kansas in Lawrence. In 1995, they returned to the Antelope Valley and lived in Palmdale, where Mr. Schweikhard continued his consulting and academic work. In the Spring of 2009, Bill and Carol moved to Round Rock, Texas. Bill was active in the Lutheran Church in every community where he lived. He also enjoyed travel and spending time with his wife of 54 years, their children and grandchildren. He is survived by his wife Carol Schweikhard of Round Rock, Texas, and his children Jo Ann Moss and husband Mark of Georgetown, Texas; Craig Schweikhard and wife Nancy of Ventura, Calif.; Keith Schweikhard and wife Sharon of Palmdale, California; and Russell Schweikhard and wife Tracy of Fairfax, Virginia. Five grandchildren also survive. They are Melanie Moss of Georgetown, Texas; Nicolas and Rachel Schweikhard of Ventura, California; and MacKenzie and Samantha Schweikhard of Fairfax, Virginia. He also is survived by his nephew Carl Bailey of Chapel Hill, North Carolina. He was preceded in death by his sister Betty Ann Bailey.
