John Griffith "Jack" London (born John Griffith Chaney; January 12, 1876 - November 22, 1916) was an American novelist, journalist, and social activist. A pioneer in the world of commercial magazine fiction, he was one of the first writers to become a worldwide celebrity and earn a large fortune from writing. He was also an innovator in the genre that would later become known as science fiction.
London was vulnerable to accusations of plagiarism, both because he was such a conspicuous, prolific, and successful writer and because of his methods of working. He wrote in a letter to Elwyn Hoffman, "expression, you see--with me--is far easier than invention." He purchased plots and novels from the young Sinclair Lewis and used incidents from newspaper clippings as writing material. In July 1901, two pieces of fiction appeared within the same month: London's "Moon-Face", in the San Francisco Argonaut, and Frank Norris' "The Passing of Cock-eye Blacklock", in Century Magazine. Newspapers showed the similarities between the stories, which London said were "quite different in manner of treatment, [but] patently the same in foundation and motive." London explained both writers based their stories on the same newspaper account. A year later, it was discovered that Charles Forrest McLean had published a fictional story also based on the same incident. Egerton Ryerson Young claimed The Call of the Wild (1903) was taken from Young's book My Dogs in the Northland (1902). London acknowledged using it as a source and claimed to have written a letter to Young thanking him. In 1906, the New York World published "deadly parallel" columns showing eighteen passages from London's short story "Love of Life" side by side with similar passages from a nonfiction article by Augustus Biddle and J. K Macdonald, titled "Lost in the Land of the Midnight Sun". London noted the World did not accuse him of "plagiarism", but only of "identity of time and situation", to which he defiantly "pled guilty". The most serious charge of plagiarism was based on London's "The Bishop's Vision", Chapter 7 of his novel The Iron Heel (1908). The chapter is nearly identical to an ironic essay that Frank Harris published in 1901, titled "The Bishop of London and Public Morality". Harris was incensed and suggested he should receive 1/60th of the royalties from The Iron Heel, the disputed material constituting about that fraction of the whole novel. London insisted he had clipped a reprint of the article, which had appeared in an American newspaper, and believed it to be a genuine speech delivered by the Bishop of London.

Did London ever accuse someone else of plagiarism?

Widespread Panic is an American rock band from Athens, Georgia. The current lineup includes guitarist/singer John Bell, bassist Dave Schools, drummer Duane Trucks, percussionist Domingo "Sunny" Ortiz, keyboardist John "JoJo" Hermann, and guitarist Jimmy Herring. The band's original drummer, Todd Nance, left in 2016. The band was formed in Athens, Georgia, in 1986, and is influenced by the Southern rock, blues-rock, progressive rock, funk and hard rock genres.
John Bell and Michael Houser met in 1981 in their dorm at the University of Georgia. Bell had been playing guitar as a solo act, and invited his new friend Houser, also a guitarist, to join him. They began living together and collaborating on music in that year, writing still-popular songs such as "Driving Song" and "Chilly Water" together. Bassist Dave Schools met Bell and Houser in 1984 and first played with them on February 24, 1985, at the A-Frame house on Weymanda Court in Athens. On February 6, 1986, Houser called childhood friend and drummer Todd Nance to sit in with Houser, Bell, and Schools for a charity event in Athens; it was their first show as "Widespread Panic." The band was named for Houser's once-frequent panic attacks. Texan percussionist Domingo S. Ortiz ("Sunny") began sitting in with the band regularly later that year. The band played in fraternities and bars regularly before Panic signed a contract with Landslide Records in 1987. In February 1987 the band played the now-legendary series of one dollar Monday night shows at the Uptown Lounge in Athens and the crucial local press began to take notice--FLAGPOLE & Athens Observer art columnist Shan Clark emphasized Widespread Panic's musical virtuosity, songwriting and professionalism. In September of the same year, they recorded their first album, Space Wrangler, at John Keane's studio in Athens. Col. Bruce Hampton is rumored to have delivered the first pressing to the band. Songs on the album included "Chilly Water," "Travelin' Light," "Space Wrangler," "Coconut," "The Take Out," "Porch Song," "Stop-Go" and "Driving Song." After Space Wrangler, touring expanded to include additional northeastern dates, along with Texas, Colorado, the west coast, and internationally to Vancouver, Canada. It was also around this time (late 1988 or early 1989) that Domingo Ortiz joined the band full-time. They played their first show in Colorado in March 1990, opening for Jerry Joseph's band Little Women. Widespread Panic signed with Capricorn Records in January 1991. Later that year, they released their major label debut, Widespread Panic (a.k.a. Mom's Kitchen). That same year Billy Bob Thornton directed the movie Widespread Panic: Live from the Georgia Theatre which was recorded over two nights in Athens, Georgia. As the band began to tour more, John Hermann ("JoJo") joined the band as a keyboardist in March 1992 replacing Dixie Dregs keyboardist T. Lavitz who joined the band a year earlier. The band continued to tour throughout the entire US in 1992 joining the famous HORDE tour with Blues Traveler, Phish, and the Aquarium Rescue Unit, among others. They released "Everyday" in March 1993 and "Ain't Life Grand" in September 1994. Panic marked their rise by playing on network television for the first time in November 1994.
