McKinley Conway, 90, founder of the World Development Federation and publisher of Site Selection magazine, died in Shiloh, Fla., on May 29.

The World Development Federation, which mounted “super projects,” conferences bringing together authorities in a wide variety of fields, was one of several organizations that he founded during his lifetime.

Others included the International Development Research Council and the Industrial Asset Management Council, among the first global real estate associations.

Mr. Conway earned bachelor’s and master’s degrees at the Georgia Institute of Technology and was inaugurated into Georgia Tech’s Engineering Hall of Fame.

He had a multifaceted career as an aviator and innovator including developing plans for the visionary “airport city” concept that is currently being implemented around the world including areas surrounding Hartsfield-Jackson Atlanta International Airport.

He founded his company Conway Data Inc. in 1947 and in 1954 launched Site Selection magazine, the first magazine ever created to focus on corporate real estate and economic development.

In the 1960s he served in the Georgia Senate and led the effort to establish Atlanta’s mass transit system, MARTA.

In 1960, Conway Data won the contract to lead the Agency of International Development/Private Enterprise Promotion to highlight the benefits of capitalism over communism in Central and South America. In 1962, Vice President Lyndon Johnson named him to a team charged with strengthening economic ties with Southeast Asia.

The author of 48 titles including “The Airport City,” he wrote 10 books during the past five years of his life and frequently posted articles on the Internet.

His survivors include his wife, the former Rebecca Kellam, two daughters, Linda Conway Duever and Laura (Jack) Conway Lyne, and two grandchildren, Adam Jones-Kelley of Atlanta and Piper Jones-Kelley of Whidbey Island, Wash.

Mr. Conway will be buried in a simple graveside service on Wednesday June 1, at 10 a.m. at the Shiloh United Methodist Church Cemetery, 11020 NW Hwy. 320. A celebration of Mac Conway’s life will be held later this year in Atlanta at a yet-to-be-determined date.

In lieu of flowers, the family requests that donations be made to either: Shiloh United Methodist Church, 11020 NW Hwy. 320, Micanopy, Fla. 32667; Hospice of Marion County, 3231 SW 34th Ave., Ocala, Fla. 34474; or the Hackleburg Helping Hands Charity Account, P.O. Box 189, Hamilton, Ala. 35570.
