Context paragraphs:
Arthur Barker: Arthur R. Barker (June 4, 1899 – January 13, 1939) was an American criminal, the son of Ma Barker and a member of the Barker-Karpis gang, founded by his brother Fred Barker and Alvin Karpis.  Generally known as "Doc", Barker was typically called on for violent action, while Fred and Karpis planned the gang's crimes.  He was arrested and convicted of kidnapping in 1935.  Sent to Alcatraz Federal Penitentiary in 1936, he was killed three years later while attempting to escape from the Rock.

Barker–Karpis gang: The Barker-Karpis Gang was one of the longest-lived criminal gangs during the Depression Era, spanning from 1931 to 1935.  The gang was founded by Fred Barker and Alvin Karpis, and 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.

Henri Young: Henri Theodore Young (born June 20, 1911 – missing since 1972) was a convicted bank robber and murderer who, while serving one of a series of prison terms, attempted a 1939 escape from Alcatraz Federal Penitentiary with four other inmates.  Two escapees were shot, and one died of his wounds; all surviving were quickly recaptured.  Two at least, Young and Rufus McCain, received sentences of solitary confinement, and served them at Alcatraz for a period of a three year (until autumn of 1942).  A little over three year after his reentering the Alcatraz general prison population (in December 1942), Young murdered fellow escapee McCain; no apparent motive was ever disclosed.  Young's subsequent trial featured a spirited, creative defense that put Alcatraz and the penal system on trial, leading to questions about how the prison was run.  Young was transferred from Alcatraz to the Medical Center for Federal Prisoners, Springfield, Missouri, in 1948, and then to Washington State Penitentiary at Walla Walla on completion of his federal sentence, to begin a life sentence for the 1933 murder conviction.

Russell Gibson: Russell "Slim Gray" Gibson (died January 8, 1935) was an American bank robber and Depression-era outlaw associated with Alvin Karpis and the Barker Gang during the late 1920s and 1930s.  Gibson spent much of his early criminal career with the Central Park Gang based in Tulsa, Oklahoma which included the Barkers, Volney Davis, Ray Terrill and other local criminal figures.  He participated in his first major robbery when he teamed with Neal Merritt and James "Cowboy" Long to rob a bank messenger in Oklahoma City of $75,000.  Gibson was arrested for this robbery but escaped from county jail prior to his trial.

Baker Beach (Alcatraz): Barker Beach is a small beach and rocky coastal area on the west side of Alcatraz Island, off the coast of San Francisco, California.  It lies just south of the long two-story New Industries Building.  During the foggy, early morning hours of Friday, January 13, 1939, five inmates - William "Ty" Martin (AZ-370), Henry Young (AZ-244), Rufus McCain (AZ-267), Dale Stamphill (AZ-435), and Arthur "Doc" Barker (AZ-268) - broke out of their D-Block cells and climbed out of a window that had its bars severed in advance, with the sabotage camouflaged with paint and putty.  The five men made it to the water's edge and began to look for driftwood to build a raft.  In the meantime, their absence was discovered and guards swarmed the island with rifles and machine guns.  Dark figures were spotted on the western shore and guards opened fire.  Stamphill was shot in the legs multiple times but recovered.  Doc Barker took a slug in the head and died several hours later.  The remaining three inmates gave up immediately and were recaptured without injury.  The beach was later named after Doc Barker by the National Park Service.

Rufus McCain: Rufus Roy McCain (July 7, 1903 – December 3, 1940) was a prisoner at Alcatraz who attempted escape with Henri Young and Arthur Barker in 1939.

Barker Black: Barker Black is a British luxury footwear brand specializing in bench-made shoes for men.  The Barker Black line is a subset of the English shoe company Barker, which was founded in 1880 by Arthur Barker.  Launched in 2005 by creative director, Derrick Miller, the Barker Black brand quickly gained the attention of the fashion media, appearing in the premiere issue of "Men's Vogue" in September 2005.  Subsequent coverage in men's fashion magazines such as "Details", "Esquire", and "GQ" followed.  In 2007, Barker Black was chosen by GQ magazine as one of the best new designers in America.

Fred Barker: Frederick George Barker (1901–1935) was one of the founders of the Barker-Karpis gang, which committed numerous robberies, murders and kidnappings during the 1930s.  He was the youngest son of Ma Barker, all of whose children were criminals.  He was killed in a lengthy gunfight with the FBI in 1935.

Kidnapping of Edward Bremer: The Kidnapping of Edward Bremer was the last major criminal enterprise of the Barker-Karpis gang.  Though successful in netting the gang a large ransom, it brought down the full force of the FBI on the gang, resulting in the death or capture of its main members in the months afterwards.  The kidnapping was organized by racketeer Harry Sawyer, and the principal kidnappers were Fred Barker, Alvin Karpis, Arthur Barker, Volney Davis and George Ziegler.

Alvin Karpis: Alvin Francis Karpis (born Albin Francis Karpavičius; August 10, 1907 – August 26, 1979), a Depression-era gangster nicknamed "Creepy" for his sinister smile and called "Ray" by his gang members, was a Canadian-born (naturalized American) criminal of Lithuanian descent known for being a leader of the Barker–Karpis gang in the 1930s.  Karpis led the gang along with Fred Barker and Arthur "Doc" Barker.  There were only four "public enemies" ever given the title of "Public Enemy #1" by the FBI and he was the only one to be taken alive.  The other three, John Dillinger, Pretty Boy Floyd, and Baby Face Nelson, were all killed before being captured.  He also spent the longest time as a federal prisoner in Alcatraz Prison, serving twenty-six years.
