In memoriam [Mr. Andre G. Clavier and Dr. George C. Southworth]

Brief biographies are provided for Mr. Andre G. Clavier and Dr. George C. Southworth highlighting their professional achievements. Mr. Clavier played a major role in the first successful demonstration of microwave transmission across the English Channel in 1931. Dr. Southworth was one of the first experimentalists to discover, identify, and apply microwave propagation in hollow metal pipes. In addition to their technical contributions, which covered a span of decades and influenced two generations of microwave people, they were also active in our Professional Society. When the Microwave Theory and Techniques Group was formed in 1952, they were members of the first National Administrative Committee. Mr. Clavier was Vice-Chairman of the first Ad Corn and Chairman of the second. Although Dr. Southworth chose not to be an officer, he was active at the Ad Corn meetings and in discussions and correspondence with other members. They were both instrumental and influential in helping to set the pattern for what many of us like to believe is one of the IEEE´s most dynamic groups. Recognizing their contributions as scientific pioneers and as concerned professionals, the National Administrative Committee, in 1959, established the status of Honorary Life Member to both honor contributions and to retain participation of the giants in our technology. Dr. Southworth was unanimously chosen our first Honorary Life Member, in 1959, and Mr. Clavier was chosen a year later.
