The Barker-Karpis Gang was one of the longest-lived criminal gangs during the Depression Era, spanning from 1931 to 1935. Founded by Fred Barker and Alvin Karpis, it was later joined by Fred's brother Arthur "Doc" Barker. Along with the three core members, the gang's network spanned up to 25 members at one point.
Although not as well known as their contemporaries the Dillinger Gang, or the Barrow Gang, the Barker-Karpis Gang was perhaps more ruthless, not only committing bank robberies but extending the activities into kidnapping as well. It is best known for the myth that it was run by the Barker brothers' mother, Kate, usually referred to as "Ma Barker".
The Barker–Karpis gang was put together by Fred Barker and Alvin Karpis in March 1931. Barker and Karpis had met in the Kansas State Penitentiary, and upon Karpis's release in March 1931, started to form the gang. The gang began robbing banks starting in mid-1931. Doc Barker later joined the gang in 1932. The gang was led by the three of them, although many others rotated in and out of the gang including Fred Goetz and Volney Davis. The gang continued their bank robbing activities until mid-1933, when they decided that robbing banks was becoming risky, and therefore decided to diverge into the field of kidnapping. Their graduation to more serious crime was mentored by corrupt police chief Tom Brown.
The Hamm and Bremer Kidnappings
In June 1933, the Barker–Karpis gang kidnapped William Hamm of Hamm's Brewery and released him on June 19, 1933. The ransom from this kidnapping netted $100,000. They then kidnapped Edward Bremer in broad daylight in St. Paul in January 1934, releasing him in February. The ransom from this kidnapping turned out to be $200,000. Unfortunately, these kidnappings brought too much negative publicity, due to the recent Urschel and Lindbergh Kidnappings, and the fact that the father of the Bremer Jr. was a personal friend of President Roosevelt, who mentioned the kidnappings in a Fireside chat. On November 27, 1934, Lester "Baby Face Nelson" Gillis, at that time the Public Enemy No. 1, was mortally wounded in a gun battle with the FBI and died later that night. The next day, Alvin Karpis was declared Public Enemy No. 1, which brought the full force of the FBI down on the Barker-Karpis Gang.
The gang had faced problems. George "Shotgun" Ziegler had been gunned down in Cicero, Illinois in March 1934, possibly due to the mob's dislike of the gang's activities. Gang member William J. Harrison was killed on January 6 by fellow members of the gang. Following the declaration of Alvin Karpis as Public Enemy No. 1, Doc Barker was arrested on January 8, 1935, along with Byron Bolton. Russel "Slim Gray" Gibson was killed resisting the arrest. Along with his arrest came a map and letters to a cottage near Lake Weir, Florida, near Ocklawaha, in which Fred Barker and his mother, Kate "Ma" Barker were hiding under an assumed name. After a four hour shootout on January 16, 1935, Fred and Ma Barker were killed. Controversy remains as to whether Ma Barker participated in the shootout, or was even a criminal at all. Alvin Karpis was nearly gunned down in Atlantic City, New Jersey, around the same time.
Karpis stayed on the move for another 16 months, pulling an armored car robbery and a train robbery in April and October 1935, before finally being arrested in New Orleans on May 1, 1936 alongside new accomplice Fred Hunter. Although Director J. Edgar Hoover personally claimed credit for Karpis's arrest, Hoover and the official FBI account of the arrest remains in question. Karpis offers his own version of the arrest in his book, The Alvin Karpis Story. The arrest of Karpis brought the FBI to fame and skyrocketed their public standing, along with J. Edgar Hoover's reputation. 
Doc Barker was sent to Alcatraz in the summer of 1935. Alvin Karpis soon followed upon his own arrest. Many other members of the gang ended up at Alcatraz prison. Doc Barker ended up being shot dead while attempting to escape in 1939.
While at McNeil Island Penitentiary Karpis began to teach guitar to the young Charles Manson, then known as “Little Charlie”. Karpis was sympathetic to Manson‘s tumultuous, institutionalized upbringing which saw him in countless orphanages, reformatories, and prisons all throughout his young life. Karpis would later pen “it (was) time someone did something for him.” He later said, "There was something unmistakably unusual about Manson. He was a runt of sorts, but found his place as an experienced manipulator of others. I did feel manipulated, and under circumstances where it hadn't been necessary."
Karpis was paroled in 1969, and deported to Canada. He moved to Spain in 1973. Karpis co-wrote two books with professional authors, one released in 1971 titled The Alvin Karpis Story, the other, released in 1979, titled On the Rock. He died on August 30, 1979, of natural causes, though it was initially believed to be a suicide or the result of foul play.
