[3] While attending the University of Austin, he met fellow student Mamie (Steiber) Shepperd of Yorktown, Texas.

[4] After a short period in private practice and two years in the military, Shepperd was elected to the Gregg County Commissioners Court in 1946 at the age of 30.

[7] On September 13, 1956, just two weeks after the Mansfield incident, John Ben Shepperd brought suit against the Texas Chapter of the National Association for the Advancement of Colored People seeking to investigate and examine files, records and accounts of the NAACP branches in Houston and Dallas.

[9] The three main charges were: 1) practicing law without a license and barratry (the offense of frequently instigating lawsuits), 2) involvement in political activities by lobbying and supporting partisan candidates, and 3) making pecuniary profit.

After his tenure as attorney general, Shepperd moved to Odessa, where he was active not only in law but also in insurance, banking, petrochemicals, public relations, and historical preservation.

In the middle 1960s, Shepperd was named trustee for the acquisition of land for the creation of Lyndon B. Johnson State Park and Historic Site along the Pedernales River in Gillespie County in the Texas Hill Country.

As Attorney General, he led multiple investigations of alleged communist infiltration of trade unions attempting to organize themselves in Texas.

[4] He was also involved in the planning and expansion of the Presidential Museum and Leadership Library, an institution on the UTPB campus dedicated to the office of the presidency.
