His father and grandfather practiced law in Wills Point[7] until his family moved from Kaufman, Texas[8] to Dallas around 1928.

On December 1, 1945, Wynne separated Eighth Naval District, New Orleans rank Lieutenant Commander, (D), USNR with numerous medals, ribbons.

In July, it was announced Nelson, Laurance, David, Winthrop, and John D. Rockefeller III would join the Wynnes, and Webb & Knapp in developing the industrial park.

Stern claimed the men stole his idea, and after 12 days of arguments Judge Paul Peurifoy rejected the $300 Million lawsuit, though held that Texas Industrial Ventures was entitled to repurchase with 60-days from Webb & Knapp six tracks of land involved for $18,000.

He said, "We felt that multiple rail service is so desirable for our tenants that, should it become necessary, we should provide it through a privately operated truck line railroad.

"[30] Construction continued through in 1957,[29] and in June 1958 the Interstate Commerce Commission gave Wynne and the Great Southwest Corp permission to build its railroad.

[32] Despite the addition of the new railroad, the Industrial Park struggled to succeed in selling retail and warehouse space to prospective businesses.

"[33] During the planning stages of the expansion, Arlington mayor Tom Vandergriff advised that Wynne and his family should visit the recently opened Disneyland in Anaheim, California.

[29] This visit inspired Wynne to change his plans, realizing he should build a park that celebrated Texas history.

[29] Under the leadership of Wynne,[34] the Great Southwest Corporation hired former Disneyland vice-president C. V. Wood's firm Marco Engineering to help design the park.

At the same time it was revealed very little progress had been made at the site aside from construction of the 32-lane bowling alley which was announced to be the first planned structure to be built.

[29] With the success of the park, Wynne was asked to contribute to the 1964 New York World's Fair, and he proposed the construction of a 2,400-seat theater.

[45] In February 1964 it was reported Wynne put $6 million into building the Music Hall, and a Texas pavilion for the fair.

In an interview with journalist Joseph Lelyveld, Wynne said as the primary financer, he would be the one to make money at the fair, adding, "I've never done anything just for fun.

[45] On July 31, 1964, Wynne's 20-year-old son, Angus III, was arrested for trespassing and assault after he tried to re-enter the pavilion after the fair closed at 2 in the morning.

The new company had bought 3,000 acres of land for more than $3 million in the Atlanta area for a new theme park location, which would go on to be Six Flags Over Georgia.

The last park that Wynne would see acquired in his lifetime under the Six Flags name was California's Magic Mountain (outside Los Angeles) in 1979.

Wynne died that same year and although he was no longer associated with the company at the time of his death, Six Flags would eventually acquire numerous other properties and become the world's largest regional theme park chain.

This resulted in Great Southwest having money difficulties because certain credit facilities have been terminated or suspended, and because other cash-producing operations were forced to cease temporarily.

[49] In October 1970 Penn Central selected Victor Palmieri as Wynne's successor as president and chief executive officer.

In November 1970 the company filed a suit in the Orange County, California Superior Court alleging the employees were overcompensated.

In November 1949, Angus and Joanne attended the Neiman Marcus annual Jamboree at the Dallas Athletic Club.

[21] In 1955, Wynne joined a statewide campaign to raise funds to support the Texas Boy Scouts of America.

[61][62] Wynne, and Winthrop Rockefeller, were among the guests invited to speak at a civic development conference being held June 1957 in Little Rock, Arkansas.
