January 19, 1988;
Autonetics Club formally, albeit probationally, reestablished. Probation to last one year; three-year additional “watch” period established after which the Club September petition for upgrade to Chapter status.
January 18, 1987
A reorganization and business meeting of the revitalized Autonetics Club of Sigma Xi was held. Stan White was elected President, Theodore J. LaChapelle was elected Secretary-Treasurer. Committee members selected were John de Nike, A. Donald Rankine, Margil W. Wadley and James B. Weddell. About a dozen other members attended. The successful bimonthly social hour/dinner/lecture format was established.
August 15, 1987
Stan White formally petitions Sigma Xi National Headquarters in the name of the Autonetics Club for a charter extension.
September 14, 1987
Stan White takes control of and responsibility for the Club to save its existence; asks all members of record for assistance. Contacts were made with all active and lapsed Sigma Xi members with Orange County ZIP codes. Ted LaChapelle volunteers to help.
September 9, 1987
Sigma Xi national headquarters notified all Autonetics Club members of record that the charter of the Autonetics Club of Sigma Xi will be revoked due to nearly a decade of Club inactivity. Concerned members contacted one another and held two meetings. Unfortunately, nothing useful emerged because of disagreements over organization, mission and leadership.
In 1974 RESA and Sigma Xi, two very similar organizations, merged to form Sigma Xi, The Scientific Research Society of North America; however, after the organization began to spread into Latin America, the Far East and Europe, the “of North America” was dropped from the name. The Autonetics RESA Branch was reclassified as a Sigma Xi “Club.” The late laser pioneer, Dr. R. A. Gudmundsen, was elected President, SAW was elected Treasurer.
May 1978; Duane L. Merry, Ph.D., creator of the award-winning PBS series, “Dimensions in Cultures,” adventurer, anthropologist, and Instructor at Orange Coast College; “Early Civilizations and my Life with the Bedouin.” This was the last meeting before the Club lapsed into inactivity for a decade after the Research Division was gutted by funding cuts and layoffs.
1965 - 1978
No paper record can be located that documents the Chapter’s 1965-1978 activities, but Stan White (Treasurer 1974-1978) has personal memories of quarterly lecture/dinner meetings since January, 1966, when he (already a Sigma Xi member) was inducted into RESA.
April 2, 1965
the Autonetics Branch of RESA, The Scientific Research Society, was formally installed by the Founding Dean of UCLA’s Engineering School, Llewellyn M. K. Boelter, Ph.D.
