1952, Kershner and Head were made partners, and the name
was once again refined to A.D. Ring & Associates. Charlie Wright
and Marvin Blumberg were hired as associates, and soon became
partners as well (in 1956 and 1960, respectively). With Ralph Cannon,
and the partnership of five, the firm
of Delta Electronics, Inc.
was founded to manufacture field equipment
used in the broadcast
consulting industry. Later, Kershner and Wright
resigned to form their own firm, buying out Delta
other five stockholders. A young engineering student, John A.
was hired in 1967. He
soon got his degree and his Professional Engineering License, and
later lead the firm as president. Andrew Donald Ring retired
practice in 1969.
Ogden Prestholdt, then Chief Engineer for CBS Radio, joined
a partner of A.D. Ring & Associates. In 1971, the firm of Kear
and Kennedy suffered difficulties following
the death of Bob Kennedy. Ring & Associates took over the assets
of K&K. This transaction was reported to Andy Ring
and Ralph Clark
while they were aboard a cruise ship anchored off the Galapagos Islands.
Dr. Frank Kear was enticed from retirement and
became a partner in the expanded Ring & Associates. - continued
