John Lawrence Seigenthaler ( /ˈsiːɡənθɔːlər/; born July 27, 1927) is an American journalist, writer, and political figure. He is known as a prominent defender of First Amendment rights.

Seigenthaler joined the Nashville newspaper The Tennessean in 1949, resigning in 1960 to act as Robert F. Kennedy's administrative assistant. He rejoined The Tennessean as editor in 1962, publisher in 1973, and chairman in 1982 before retiring as chairman emeritus in 1991. Seigenthaler was also founding editorial director of USA Today from 1982 to 1991. During this period, he served on the board of directors for the American Society of Newspaper Editors, and from 1988 to 1989 was its president.

Born in Nashville, Tennessee, Seigenthaler is the oldest of eight siblings. He attended Father Ryan High School and served in the U.S. Air Force from 1946 to 1949. After leaving the service, Seigenthaler was hired at The Tennessean.

While working at The Tennessean, Seigenthaler took courses in sociology and literature at Peabody College, now part of Vanderbilt University. He also attended the American Press Institute for Reporters at Columbia University.

The word asshole, a variant of arsehole, which is still prevalent in British and Australian English, is a vulgar to describe the anus, often pejoratively used to refer to people.

The word arse in English derives from the Germanic root *arsaz, which originated from the Proto-Indo-European root *ors — meaning buttocks or backside. The combined form arsehole is first attested from 1500 in its literal use to refer to the anus. The metaphorical use of the word to refer to the worst place in a region, e.g., "the arsehole of the world") is first attested in print in 1865; the use to refer to a contemptible person is first attested in 1933. In the ninth chapter of his 1945 autobiography, Black Boy, Richard Wright quotes a snippet of verse that uses the term: "All these white folks dressed so fine / Their ass-holes smell just like mine ...". Its first appearance as an insult term in a newspaper indexed by Google News is in 1965. As with other vulgarities, these uses of the word may have been common in oral speech for some time before their first print appearances. By the 1970s, Hustler magazine featured people they did not like as "Asshole of the Month." In 1972, Jonathan Richman's Modern Lovers recorded his song "Pablo Picasso," which includes the line "Pablo Picasso was never called an asshole."
