C&P Telephone has taken the first step in a comprehensive restructuring of its operations in an effort to provide better and more personalized service to its customers. The change, which becomes effective on the first of the year, is designed to align more closely the utility's operations with the principal market segments it serves, while still fulfilling the need for local leadership.

The plan calls for four officer-level units at C&P headquarters in Washington: business, residence, net-work operations and central staff. J. O. Koch, vice president-marketing, was named vice president-business; J. H. Butt, vice president-customer services and network services, was named vice president-residence; C. E. Morgan, vice president-engineering, will become vice president-network operations and W. S. Daron, general manager of the Washington suburban area, C&P of Maryland, was named vice president-central staff. Ralph W. Frey, C&P vice president, will continue to be responsible for telephone service for C&P customers in the District.

Vice presidents of each of the other C&P operating areas are L. C. Tait, Virginia; T. M. Gibbons, Maryland, and F. R. Hoffman, West Virginia.

Officers of the four new units will report to W. E. Fisher, executive vice president and chief operating officer.

Other officers are R. A. Levetown, vice president and general counsel; L. E. Dyer, vice president-personnel; J. W. Boykin, vice president-secretary and treasurer; J. E. Blackburn, vice president-revenues; R. B. Snyder, vice president-comptrollers operations and J. H. Zahn, vice president-public relations.

Other personnel realignments of middle and lower level managers will be announced later this month.

Donald W. Nyrop, chairman and chief executive officer of Northwest Airlines, announced he will retire on Dec. 31. Nyrop will stay on as a member of the airline's board and the role of chief executive will be assumed by M. J. Lapensky, president and chief operating officer.

During his 24 years as head of Northwest, Nyrop was instrumental in turning the company around, making it one of the most profitable U.S. carriers. Last year the airline earned a record $92.7 million on revenue of $1 billion.

Nyrop served as chairman of the Civil Aeronautics Board in 1951 and 1952 and Federal Aviation administrator in 1949 and 1950, the only airline chief executive to do so.
