Dr. Stone was appointed Director of the Jet Propulsion Laboratory on January 1, 1991. In this capacity he also serves as a Vice President of Caltech. Dr. Stone earned his associate of arts degree in 1956 from Burlington Junior College before continuing his studies at the University of Chicago. After receiving his master of science (1959) and Ph.D. (1964) degrees in physics, he joined Caltech as a research fellow in physics. Stone was subsequently appointed senior research fellow and assistant professor (1967), associate professor (1971), professor of physics (1976), chairman of Caltech's Division of Physics, Mathematics and Astronomy (1983 - 1988), and Vice President for Astronomical Facilities (1988 - 1990). Since his first cosmic-ray experiments on Discoverer satellites in 1961, Stone has been a principal investigator on nine NASA spacecraft missions and a co- investigator on five other NASA missions for which he developed high resolution instruments for measuring the isotopic and elemental composition of energetic cosmic-ray nuclei. Using these instruments, Stone and his colleagues undertook some of the first studies of the isotopic composition of three distinct samples of matter. The matter arrives at Earth as cosmic rays from nearby regions in our galaxy, as solar energetic particles from the Sun, and as the anomalous component from the local interstellar medium. These instruments also have been used for studies of planetary magnetospheres, including the discovery of energetic sulfur and oxygen ions from Jupiter's satellite, Io. Stone also jointly developed a large-area electronic satellite instrument for measuring the abundance of very rare heavy galactic cosmic-ray nuclei, such as lead and platinum, and collaborated in the development of an imaging gamma-ray telescope. Since 1972, Dr. Stone has served as the project scientist for the Voyager Mission, participating in both hardware development and mission operations. Following launch in 1977 of the twin Voyager spacecraft, he coordinated the efforts of 11 teams of scientists in their studies of Jupiter, Saturn, Uranus and Neptune. Among his many scientific awards and honors, Stone was a Sloan Foundation fellow and has received the NASA Exceptional Scientific Achievement Medal, the NASA Distinguished Service Medal, the American Institute of Aeronautics and Astronautics Dryden Medal and Space Science Award, and the NASA Distinguished Public Service Medal. He is the recipient of the NASA Outstanding Leadership Medal, the Aviation Week and Space Technology Aerospace Laurels Award, the National Space Club Science Award, the Association for Unmanned Vehicle Systems National Award for Operations, the National Medal of Science, the American Philosophical Society Magellanic Award, the American Academy of Achievement Golden Plate Award and the COSPAR Award for Outstanding Contribution to Space Science. He has received honorary degrees from Washington University, St. Louis, Harvard University, and the University of Chicago. Stone is a member of the National Academy of Sciences and the International Academy of Astronautics. He is a fellow of the American Physical Society, the American Geophysical Union, and the American Institute of Aeronautics and Astronautics. He is also a member of the American Astronomical Society, the International Astronomical Union and an honorary member of the Astronomical Society of the Pacific. #####
