Bishop James Cannon, Jr. (13 November 1864 – 6 September 1944) was an American Bishop of the Methodist Episcopal Church, South, elected in 1918. He was also a prominent leader in the temperance movement in the U.S.A. in the 1920s until derailed by scandal. H.L. Mencken said in 1934: "Six years ago he was the undisputed boss of the United States. Congress was his troop of Boy Scouts, and Presidents trembled whenever his name was mentioned.... But since that time there has been a violent revolution, and his whole world is in collapse.
The degree of Doctor of Divinity was conferred upon Cannon in 1903 by Randolph-Macon College. Princeton University awarded him an honorary D.D. degree.
After the death of Anti-Saloon League leader Wayne Wheeler in 1927, Cannon, chairman of the Methodist Board of Temperance and Social Service, emerged as the most powerful leader of the temperance movement in the United States. Mencken said of Cannon that, "Congress was his troop of Boy Scouts and Presidents trembled whenever his name was mentioned."
When the 1928 Democratic Convention chose wet leader Alfred E. Smith for president, Cannon was outraged at this "betrayal" of the dry cause, and helped organize the Anti-Smith Democratic movement in the South. Soon Virginia and upper South states were leaning toward Republican Herbert Hoover Hoover and he did carry them. However the new Virginia machine led by Byrd and Glass supported Smith and decided Cannon had to be destroyed for ruining party unity in the Solid South. Glass sent investigators to look into Cannon's financial dealings. Cannon, who had never been a candidate for political office, assumed Hoover's victory in Virginia made the state ripe for himself, and spread rumors he would challenge Glass for the Senate seat. He supported a coalition of Anti-Smith Democrats and Republicans to take win the governorship for Dr. William Moseley Brown of Washington and Lee College.
One biographer described Cannon as an unpleasant and deceitful person. Although he “loved power and prestige, profit and pleasure,“ Cannon was a distant and aloof individual. One Anti-saloon League colleague described him as “cold as a snake” and another, with whom he has worked closely for forty years, reported having never seen him laugh and rarely smile.
Glass released information that Cannon had been engaged in shady or illegal stock market manipulations. Fellow bishops called for a church investigation. Reports that he used Methodist church money to support the Anti-Smith Democrats in 1928 led to federal investigations. Cannon proclaimed his innocence, but with disclosure of the wartime hoarding, the charges were mounting faster than his friends could deny them. Cannon's candidate was defeated for governor, and Glass kept pushing for more action. In 1930 the bishops decided to bring Cannon to trial before a church court, which voted not to find him guilty by a vote of 54 to 11. Then the national newspapers published private letters between Cannon and his secretary showing they were having an affair before his first wife died. The bishops reopened the case and the church again voted not to convict its bishop, this time from the adultery charges. In October 1931, a federal grand jury brought criminal charges against Cannon for violating federal election laws, alleging he borrowed $65,000 for the campaign but kept $48,000 for himself. After a complex series of trials and appeals Cannon was not found guilty in 1934, but the revelations had destroyed his stature. The highly publicized episodes left Cannon's reputation ruined and helped discredit the prohibition movement as immoral, thus contributing to the repeal of prohibition.
Cannon died 6 September 1944 and is buried at Hollywood Cemetery in Richmond, Virginia.
