Dr. Charles Stark Draper, the "father of inertial navigation," evolved the theory, invented and developed the technology, and led the effort that brought inertial navigation to operational use in aircraft, space vehicles, and submarines.

Born in Windsor, Mo., on Oct. 2, 1901, Dr. Draper began his college work in arts and sciences at the University of Missouri in 1917. In 1919, he entered Stanford University, Calif., and graduated in 1922 with a B.A. in psychology. He entered MIT the same year, earning an S.B. in electrochemical engineering in 1926, an S.M. in 1928 without specification of department, and an Sc.D. in physics in 1938.

Founder of Draper Laboratory in Cambridge, Mass., and Institute Professor Emeritus at the Massachusetts Institute of Technology, "Doc" Draper began the foundation for those achievements as an assistant professor in the Department of Aeronautics and Astronautics at MIT in 1935. He advanced to the post of Institute Professor in 1966. During his tenure at MIT, he also held posts as Associate Professor and Department Head. He extended the curriculum of courses in the fields of instrument engineering and fire control while he was head of the Department of Aeronautics and Astronautics. He wrote extensively in the fields of instrumentation and control, and he served as a consulting engineer to many aeronautical companies and instrument manufacturers. He held a number of patents for measuring and control equipment.

Dr. Draper's small team of students and technicians at MIT expanded to become MIT's Instrumentation Laboratory. The Laboratory was later divested from MIT in 1973, when it formed a separate, nonprofit research and development laboratory -- The Charles Stark Draper Laboratory, Inc.

Dr. Draper stood among the pioneer members of the first group of aircraft engineers. Such monumental efforts as the Apollo landing on the moon and development of guidance systems or components for all deployed strategic missiles bear the stamp of his genius. Nationally, Dr. Draper's work has created a multibillion-dollar industry.

First sponsored by the Sperry Gyroscope Co., Dr. Draper's engineering work led to the development of the Mark 14 gunsight during World War II. He continued work with gun pointing and firing control developments until the late 1950s, which earned him the title "Mr. Gyro" because of the persistence and effectiveness with which he applied the gyroscope to guidance and control instruments and to gun, bomb, and rocket pointing and firing control instruments and systems.

His later research resulted in the development of a complete inertial navigation system for manned and unmanned vehicles, which performs successfully in unfavorable weather and does not rely on information from external sources.

Inertial guidance systems use gyroscopes (rotating devices that react to changes in direction) and accelerometers (instruments that detect changes in velocity over time) to keep a steady course. The information obtained from the gyroscopes and the accelerometers is fed into a computer, which calculates the degree of drift from the intended course and recommends appropriate corrections. Completely automatic inertial navigational systems can sense tiny deviations from the intended course and quickly correct them, resulting in very precise navigation anywhere in the world. Before Draper developed his inertial guidance systems, navigators depended on more laborious methods, such as celestial navigation and radio navigation.

In 1942, the USS South Dakota, using Dr. Draper's gunsights, shot down 32 Japanese attacking aircraft, an unprecedented anti-aircraft score. Under Dr. Draper's supervision, the MIT FEBE system in 1949 was the first to employ the inertial properties of gyroscopic instruments for the purpose of aircraft navigation. The Space Inertial Reference Equipment (SPIRE) followed in 1953. As the first fully inertial system, SPIRE is considered a milestone in the development of the inertial art. SPIRE Jr., an improved version of the system, was successfully flight-tested in 1957.

Dr. Draper's work on inertial navigation systems for marine vessels proved successful in the 1954 sea tests of MAST (Marine Stable Element). This led to the SINS (Submarine Inertial Navigation System) later that year.

The Air Force applied Dr. Draper's work on inertial guidance for intercontinental ballistic missiles to the THOR guidance system. Since 1957, the Laboratory has developed the guidance systems for the family of Fleet Ballistic Missiles for the US Navy: Polaris, Poseidon, Trident I, and Trident II.

Work on the guidance and navigation system for NASA's historic Apollo moon landing was the largest single program at the Laboratory until the Trident II program.

Dr. Draper was a member of several government science advisory groups, and served as chairman of the National Inventors Council. He was a past president of the International Academy of Astronautics, an Honorary Fellow of the American Institute of the Aeronautical Sciences and the British Institution of Mechanical Engineers, and an honorary lifetime member of the Instrument Society of America. He held an honorary fellowship with the British Interplanetary Society and the Royal Aeronautical Society, and he was an honorary member of the German Society for Guidance and Navigation and the British Institute of Navigation.

He was also a fellow of the American Physical Society, the American Academy of Arts and Sciences, the American Society of Mechanical Engineers, the American Association for the Advancement of Science, the Institute of Electrical and Electronics Engineers, the American Astronautical Society, and he was a member of the National Academy of Engineering, the National Academy of Sciences, the American Institute of Consulting Engineers, the Society of Automotive Engineers, the American Ordnance Association, the American Society for Engineering Education, the Massachusetts Society of Professional Engineers, the New York Academy of Sciences, and the French National Academy. He was a past president of the MIT Soaring Society, and a member of Sigma XI, Tau Beta Pi, and Sigma Alpha Epsilon.

Among his more than 70 honors and awards, 5 have come from foreign countries, including the U.S.S.R. and Czechoslovakia. He was inducted into the National Inventors Hall of Fame and into the International Space Hall of Fame.

He received the prestigious Langley Medal of the Smithsonian Institution, the NASA Public Service Award, the Dr. Robert H. Goddard Trophy of the National Space Club, and the National Medal of Science from President Lyndon Johnson.

Dr. Draper was named the New England Inventor of the Year in 1981. In 1978, MIT established the Charles Stark Draper Professorship of Aeronautics and Astronautics in his honor. Dr. Draper received the "Engineering for Gold Award" from the National Society of Professional Engineers in 1984. The society cited his work in inertial guidance systems as one of the 10 outstanding engineering achievements of the past 50 years.

Among the honorary degrees he received are doctoral degrees from Eidgenossische Technische Hochschule, Zurich, Switzerland, in 1966; the University of Portland, Portland, Oregon, in 1970; the University of Missouri, Rolla, in 1975; and Boston University in 1984.

Many of Dr. Draper's former students are leaders in government, industry, the military, and academia.

Dr. Draper died in July 1987. In tribute to his memory, Draper Laboratory endowed the Charles Stark Draper Prize, an international engineering award administered by the National Academy of Engineering. The Prize is awarded annually to individuals whose outstanding engineering achievements have contributed to the well-being and freedom of all humanity.
