The Smithfield Herald, established in 1882 by F. T. Booker, E. G. Smith, and John W. Lassiter (who was not a close relative of the family that later controlled the Herald through much of the twentieth century), was the oldest newspaper still operating in Johnston County in the early 2000s. The newspaper was started the same year that Smithfield acquired its first railroad, signaling the beginning of commercial growth for the Johnston County seat, which had not advanced beyond courthouse-village status since its incorporation in 1777.
Thomas J. Lassiter Sr., a schoolteacher, became editor of the Herald in 1896. His untimely death in 1920 prompted his widow, Rena Bingham Lassiter, to follow him as editor. Her son, Thomas J. Lassiter Jr., joined her in 1933, after his graduation from college. His career as editor and publisher extended until 1980, when the Lassiter family sold the Herald to the News and Observer Publishing Company of Raleigh. Wingate Lassiter served the Herald as a third-generation editor until 1994.
The Smithfield Herald received journalistic acclaim throughout the twentieth century. In 1922, under editor Rena Lassiter, it won an award as the best semiweekly or weekly newspaper in the state-the first time the North Carolina Press Association had bestowed such an honor. In 1982 Thomas J. Lassiter Jr. was inducted into the North Carolina Journalism Hall of Fame in recognition of his long career of editorial and community leadership. In 1995 the Herald became a property of California-based McClatchy Newspapers when McClatchy purchased the Raleigh News and Observer and its subsidiaries.
