Arizona Donnie Barker (née Clark; October 8, 1873 – January 16, 1935) better known as Ma Barker, and sometimes as Kate Barker, was the mother of several criminals who ran the Barker gang during the "public enemy era", when the exploits of gangs of criminals in the U.S. Midwest gripped the American people and press. She traveled with her sons during their criminal careers.
After Barker was killed during a shoot-out with the FBI, she gained a reputation as a ruthless crime matriarch who controlled and organized her sons' crimes. J. Edgar Hoover described her as "the most vicious, dangerous and resourceful criminal brain of the last decade". Ma Barker has been presented as a monstrous mother in films, songs and literature. However, those who knew her insisted she had no criminal role.

Born Arizona Clark in Ash Grove, Missouri, the daughter of John and Emaline (Parker) Clark, her family called her "Arrie". In 1892 she married George Barker, in Lawrence County, Missouri. The couple had four sons - Herman (1893–1927), Lloyd (1897–1949), Arthur (1899–1939) and Fred (1901–1935). The 1910 to 1930 censuses and the Tulsa City Directories from 1916 to 1928 show that George Barker worked in a variety of generally low-skilled jobs. From 1916 to 1919, he was at the Crystal Springs Water Co. In the 1920s, he was employed as a farmer, watchman, station engineer, and clerk. An FBI document describes him as "shiftless" and says the Barkers paid no attention to their sons' education. As a result, they were all "more or less illiterate".
Barker's sons committed crimes as early as 1910, when Herman Barker was arrested for highway robbery after running over a child in the getaway car. Over the next few years, Herman and his brothers Lloyd, Fred and Arthur were repeatedly involved in crimes of increasing seriousness, including robbery and murder. They were inducted into major crime by the Central Park gang. Herman died on August 29, 1927, in Wichita, Kansas, after a robbery and confrontation with police that left one officer dead. He shot the officer at point blank range in the mouth. He killed himself to avoid prosecution when he was seriously wounded after crashing his car. In 1928, Lloyd Barker was incarcerated in the federal penitentiary at Leavenworth, Kansas, Arthur "Doc" Barker was in the Oklahoma State Prison, and Fred was in the Kansas State Prison.
George is last listed living with his wife in the 1928 Tulsa city directory. He was either thrown out by Arrie, as some say, or he left when life with his criminal family became intolerable. According to writer Miriam Allen deFord, after Herman's death and the imprisonment of his other sons, George "gave up completely and quietly removed himself from the scene." The FBI claimed that George left Ma for other reasons: because she had become "loose in her moral life" and was "having outside dates with other men". They noted that though George was not a criminal, he was willing to "profit" from his son's crimes after their deaths by claiming their assets as next of kin. However, a family friend recalled that George and Arrie argued about their children's "dissolute life". While Arrie "countenenced their wrongdoings", George refused to accept them. The crunch came when George refused to support Lloyd after his arrest, insisting he should be punished for his crime. Arrie did everything she could to get her sons off, no matter what they had done.
From 1928 to 1931 Ma lived in "miserable poverty" in a "dirt-floor shack" with no husband and no job, while all her sons were in jail. This may have been when she became "loose" with local men, as the FBI suggested. By 1930 Arrie was living with a jobless man named Arthur W. Dunlop (sometimes spelled "Dunlap"). She is described as his wife on the 1930 census of Tulsa, Tulsa County, Oklahoma. Things improved for her in 1931 after her son Fred was released from jail. He joined former prison-mate Alvin Karpis to form the Barker-Karpis gang. After a series of robberies, Fred and Karpis killed sheriff C. Roy Kelly in December 1931, an act that forced them to flee the territory. Ma and her lover Dunlop traveled with them, using various false names during their itinerant crime career. A wanted poster issued at this time offers $100 reward for the capture of "Old Lady Arrie Barker" as an accomplice. After this, she was usually known to gang members as "Kate".
St Paul and Wisconsin
When Arthur was released in 1932, he joined Fred and Karpis. The core gang was also supplemented by other criminal associates. The gang moved first to Chicago, but decided to leave because Karpis did not want to work for Al Capone. Racketeer Jack Peifer suggested that they should come to St. Paul, Minnesota, a town which had a reputation at the time as a haven for wanted criminals. The Barker-Karpis gang's most infamous crimes were committed after the move to St. Paul, during their residency in a string of rented houses in and around the town. In St. Paul, the gang operated under the protection of the city's corrupt police chief, Thomas "Big Tom" Brown, and under his guidance, graduated from bank robbers to kidnappers.
Ma's common-law husband Arthur Dunlop was said to be loose-lipped when drunk, and was not trusted by members of the gang. He was described as a "pain in the ass" by Karpis. While at one hideout, a local resident identified the gang from photographs in True Detective magazine, and told the police. Brown tipped off the gang, and they escaped. Wrongly believing that Dunlop's loose lips had given them away, they apparently murdered him while traveling. His naked body, with a single bullet wound to the head, was found near Webster, Wisconsin. Though Tom Brown's involvement in the gang's escape could not be proved, he was demoted to the rank of detective and was later dismissed from the police force. For a time the gang relocated to Menomonie, Wisconsin.
During this time, Fred Barker stashed Ma Barker in a variety of hotels and hideouts. The purpose was to keep her from learning much about the gang's crimes, as well as to separate her from the gang's girlfriends, with whom she did not get along. Indeed the FBI later claimed that Ma would try to break up any relationships, so that "other women in the gang" did their best to avoid Ma. By 1933 most of the gang were back in St. Paul, where they planned and carried out two kidnappings of wealthy local businessmen. After successfully obtaining $100,000 ransom after abducting William Hamm, they then arranged the kidnapping of Edward Bremer, from which they netted a $200,000 ransom. The FBI first connected the gang to the William Hamm kidnapping by using a then new method of latent fingerprint identification. With the FBI now on the case and without Tom Brown supplying information, the gang decided to leave St. Paul. They moved to the Chicago area, renting apartments for Ma Barker while they tried to launder the ransom.
FBI agents discovered the hideout of Barker and her son, Fred, after Arthur "Doc" Barker was arrested in Chicago on January 8, 1935. A map found in his possession indicated that other gang members were in Ocklawaha, Florida. The FBI soon located the house where the gang was staying after identifying references to a local alligator named "Gator Joe", mentioned in a letter sent to Doc. They had rented the property under the pseudonym "Blackburn", claiming to be a mother and sons wanting to vacation in a country retreat.
Agents surrounded the house at 13250 East Highway C-25 on the morning of January 16, 1935. Unknown to the FBI, Karpis and other gang members had left three days before, leaving only Fred and Ma in the house. Ordered to surrender, Fred opened fire; both he and his mother were killed by federal agents after an intense, hours-long shootout. Allegedly, many local people came to watch the events unfolding, even holding picnics during the gunfire. After gunfire ceased coming from the house, the FBI ordered local estate handyman Willie Woodbury to enter the house wearing a bulletproof vest. Woodbury reported that there was no one inside alive.
Both bodies were found in the same front bedroom. Fred's body was riddled with bullets, but Ma appeared to have died from a single bullet wound. According to the FBI's account, a Tommy gun was found lying in her hands. Other sources say it was lying between the bodies of Ma and Fred. Their bodies were put on public display, and then stored unclaimed, until October 1, 1935, when relatives had them buried at Williams Timberhill Cemetery in Welch, Oklahoma, next to the body of Herman Barker.
Controversy over leadership of Barker gang
The popular image of her as the gang's leader and its criminal mastermind, portrayed in films such as Ma Barker's Killer Brood (1960), Bloody Mama (1970) and Public Enemies (1996), is widely regarded by historians as fictitious. The suggestion that she participated in the shoot-out in which she died has also been treated with skepticism. Many, including Karpis, have suggested that the myth was encouraged by J. Edgar Hoover and his fledgling Federal Bureau of Investigation (FBI) to justify his agency's killing of an old lady. After her death, Hoover claimed that Mrs. Barker was "the most vicious, dangerous and resourceful criminal brain of the last decade". He also claimed that she enjoyed the lifestyle that was the fruit of her sons' crimes and supposedly had a string of lovers.
Though her children were undoubtedly murderers and their Barker-Karpis Gang committed a spree of robberies, kidnappings, and other crimes between 1931 and 1935, there is no evidence that "Ma" was their leader or was even significantly involved. Mrs. Barker certainly knew of the gang's activities and even helped them before and after they committed their crimes. This would make her an accomplice, but there is no evidence that she was ever an active participant in any of the crimes themselves or was even involved in planning them. Her role was in taking care of gang members, who often sent her to the movies while they committed crimes. According to Claire Bond Potter, "Her age and apparent respectability permitted the gang to hide out 'disguised' as a family. As 'Mrs. Hunter' and 'Mrs. Anderson', she rented houses, paid bills, shopped, and did household errands. Age made Kate more socially invisible than a moll."
Alvin Karpis, the gang's second most notorious member, later said that Ma was just "an old-fashioned homebody from the Ozarks...superstitious, gullible, simple, cantankerous and, well, generally law abiding". He concluded that,
|“||The most ridiculous story in the annals of crime is that Ma Barker was the mastermind behind the Karpis-Barker gang. . . . She wasn't a leader of criminals or even a criminal herself. There is not one police photograph of her or set of fingerprints taken while she was alive . . . she knew we were criminals but her participation in our careers was limited to one function: when we traveled together, we moved as a mother and her sons. What could look more innocent?||”|
This view of Ma Barker is corroborated by notorious bank robber Harvey Bailey, who knew the Barkers well. He observed in his autobiography that Ma Barker "couldn't plan breakfast" let alone a criminal enterprise.
Writer Tim Mahoney argues that the real force behind the gang was the corrupt St. Paul law-enforcement system, especially under Police Chief Tom Brown. Before they met him, they were nothing more than a "bumbling band of hillbilly burglars" who would have been captured or killed long before becoming nationally notorious. "Had the Barker gang never come under Brown's protection, Ma Barker might have died lonesome in the Ozarks, an impoverished obscure widow."

In film and television
- "Ma Webster", played by Blanche Yurka in the 1940 film Queen of the Mob is based on Barker. Changes in the names and depiction of events were at the request of the FBI.
- The character of "Ma Jarrett" in the 1949 James Cagney film White Heat is thought to be based on Ma Barker.
- In the 1957 docudrama Guns Don't Argue Ma is portrayed by Jean Harvey.
- "Ma Barker and Her Boys", an episode of 1959 fictional TV series The Untouchables, pits Federal Agent Eliot Ness against the Barker clan, and depicts Ness as leading the assault on Ma Barker and her sons at their Florida hide-out. In this version, Lloyd, Fred and Doc are all present at the final shootout. Ma was played by Claire Trevor. In real life Ness worked for the Department of Treasury, not the FBI, and had nothing to do with the Barker/Karpis case. The FBI objected to the fact that Ness was depicted as the leader of the attack on the gang.
- The 1959 movie The FBI Story, starring Jimmy Stewart, portrayed a number of deaths of 1930s-era criminals, including Ma Barker. In the scene, she was shown firing at law officers before finally being shot. (She was portrayed by Jane Crowley, though the role was uncredited.)
- Lurene Tuttle portrayed Ma Barker in the low-budget feature film Ma Barker's Killer Brood (1960). The film's scrolling text refers to her as a "sadistic...master of crime" and "evil genius". It portrays her controlling a gang that includes John Dillinger and Baby Face Nelson, constantly outwitting their rival Machine Gun Kelly.
- Ma was played by Joan Blondell in an episode of the 1961 TV series The Witness, which took the form of a mock-trial of historical individuals before a "committee" of lawyers. Her son Lloyd and various accomplices appear as witnesses.
- In the 1966 Batman series, one of the villains in series one was "Ma Parker" (played by Shelley Winters), a villainous mob boss based on Ma Barker. Ma Parker along with her three sons and one daughter almost managed to defeat the Dynamic Duo in the series.
- Barker's story was also adapted in the low-budget film Bloody Mama (1970). The movie starred Shelley Winters as Ma Barker. In this film her criminality follows from childhood sexual abuse by her family.
- "The Ma Gantry Gang", featured in the first episode of the 1974 TV series The Manhunter was based on Barker and her sons. Ma Gantry was played by Ida Lupino.
- Eileen Heckart played Ma in the 1974 film The FBI Story: the FBI Versus Alvin Karpis, Public Enemy Number One.
- The DuckTales version of Disney's Beagle Boys (the series lasted from 1987-1990), a gang of criminals, is led by their mother Ma Beagle, who is based on Ma Barker. She is absent from the original comics by Carl Barks.
- Another retelling of the legend occurred in the 1996 movie Public Enemies starring Theresa Russell. As in Bloody Mama, she is depicted as a victim of sexual abuse which brutalizes her.
- In the 1985 film The Goonies Ma Fratelli is loosely based on Ma Barker.
- In the movie Six Pack starring Kenny Rogers there's a line where he calls breezy " Ma Barker and her boys"
- Maw Famon and her thug sons who battle it out with Dick Tracy in a December 1935 comic strip are based on Ma Barker and her boys.
- While The Daltons of the Lucky Luke comic book series, were originally based on the real Dalton Gang, their mother Ma Dalton is clearly inspired by Ma Barker. Coincidentally, their gang consists of four instead of three Dalton brothers.
- Crime author James Hadley Chase based some of the characters in his first novel, No Orchids for Miss Blandish (1939), on Ma Barker and her sons.
- John Eaton composed an opera, Ma Barker, in 1955.
- In 1977, West German disco band Boney M. released a hit single titled "Ma Baker" (Barker was changed into Baker because it sounded better), which was later covered by German Comedy Rock band Knorkator, and has since been covered by German heavy metal band Axxis and sampled by Lady Gaga in her single "Poker Face". The song's title and lyrics are clearly about Ma Barker.
- The band Maylene and the Sons of Disaster (formed in 2004) are named after the group of criminals and their songs are based on the gang's history. Band member Dallas Taylor has said: "Maylene and the Sons of Disaster is made up of five dudes who play the role of the Barker sons, and in these songs we speak as though we were them, telling any who would listen that a life lived unjustly will meet divine justice on the other side. We also wanted to think of the most crazy backwoods theme possible for this band. Since Ma was backwoods, and we are backwoods, this is the way it had to be."
- Former wife of gangsta rap pioneer Kool G Rap and fellow MC also goes under the name of Ma Barker. They had at one point formed a group called 5 Family Click, releasing a collective album and surfacing on mixtapes.
- Composer Michel Wintsch and writer Gérald Chevrolet adapted the writings of Marguerite Yourcenar to create the opera "Ma Barker" in 1996.
- Gator Joe's Beach Bar and Grill in Ocklawaha, Florida was named after a large alligator that lived in Lake Weir. The FBI killed Fred and Ma Barker in Ocklawaha, Florida (Marion County), after the FBI discovered "Ma" by tracking letters she sent to her other son, telling him about "Gator Joe". The restaurant's website displays a wanted poster for the Barker-Karpis gang.
- Lake Weir Chamber of Commerce stages an annual "Ma Barker Shootout" on "Ma Barker day" in a building near the actual location of her death.
- The Barker deathhouse in Ocklawaha, Florida was listed for sale on August 16, 2012. The bidding began at one million dollars and included the original furnishings, but the house ultimately went unsold. In 2015, the Florida state senate proposed a bill for $500,000 to repair and preserve the house as an historic landmark, but the bill was rejected. The house is currently listed as off-market.
