The Reaction Research Society is the oldest continuously operating
amateur experimental rocket group in the United States. Originally beginning under the name of the Southern California Rocket Society, the Society was founded on 6 January, 1943 by George James. Because of confusion in identity with the California Rocket Society, the name was changed on 17 March, 1943 to the Glendale Rocket Society. After a few years of operation under that name, the Reaction Research Society came into official existence when this new name was adopted on 31 March 1946, replacing that of the Glendale Rocket Society. The leading organizers at that time were Robert DeVoe, David Elliott, Carroll Evans, Jr., George James, John Cipperly, and Walter Lee Rosenthal. As of this writing, in the fall of 1996, five of these original members are still honorary members in the Society fifty three years after its founding. In the beginning years, Society members designed, built, and launched hundreds of solid and liquid propellant rockets. Beginning in June of 1947, many rocket mail flights were conducted by the group. This first flight carried U.S. mail across the Colorado River from Winterhaven, California to Yuma, Arizona. In 1949 and 1950 members launched the first liquid monopropellant rocket from a desert test site just south of the town of Mojave. Static testing of many different liquid propellant rocket systems followed and the zinc dust and sulfur rocket design known as the standard RRS Beta was developed and perfected. On 7 December 1954, the Reaction Research Society was incorporated in the state of California.

In 1955, the Society acquired the property north east of the town of Mojave that it still uses today for flight and static rocket test activities. In the heyday of the U.S. space program during the late 1950's and on into the 1970's, the Society enjoyed a fairly large and diverse membership. Professional aerospace engineers, high school and college students, and others of all professions and educational backgrounds were joined by a common interest in the science that was taking man into space for the first time. Providing a unique opportunity to safely conduct live firing test of substantial rocket propulsion systems, the Society's activities were a great educational experience for many members, spectators, and family members. Dwindling somewhat in the number of members in the late 1970's and into the mid 1980's, the Society, nonetheless, maintained a core of amateur rocketry expertise. Members continued to build and fly rockets at the Mojave Test Area, have regular meetings, and publish reports and news letters. However, starting in 1989, the Society began a great resurgence of activity and membership growth. Many new members were interested in liquid rocket propulsion, hybrid propulsion, and new composite solid propellants. Membership grew from twenty or so local members to nearly two hundred members by 1996.
In the many years since it was formed, RRS members have static tested and launched several thousand amateur built rockets using solid, hybrid, and liquid propellants. These vehicles ranged in size from one to twenty feet in length and have produced thrusts up to 10,000 pounds. Many present and former members who gained their first experiences with rockets in the Society are now employed in various capacities within the aerospace and rocket industries. The Reaction Research Society remains dedicated to the goals and principles set down in its original charter.
The Society today continues, as a non-profit amateur organization, to promote experimental rocketry as an educational tool and to further general interest in reaction propulsion and its applications. In addition, the Society maintains facilities and provides the technical experience necessary for safe educational opportunities in rocket design and test activities. Members from around the United States are building rocket systems to test with the Society at the Mojave Test Area. Members in foreign countries regularly communicate with local members and some, as far away as Great Brittain, are building vehicles to test here in the United States. The Society has also formed two chapters, one in northern California and a second in Pennsylvania. Members in those areas meet and conduct amateur rocketry activities locally while maintaining close ties with the Southern California parent organization. With the ongoing improvements to the Society's test facilities and the ever increasing sophistication of the projects being undertaken, the Reaction Research Society has grown into the largest and most vibrant of the amateur experimental rocket groups in the world today.
