Jacob Leon Rubenstein (March 25, 1911 – January 3, 1967), who legally changed his name to Jack Leon Ruby, was a nightclub operator in Dallas, Texas.

He is best known as the man who shot the man who (supposedly?) shot the President.

Ruby murdered Lee Harvey Oswald, the man who (according to four government investigations) assassinated President John F. Kennedy.

Some contend that Ruby was involved with major figures in organized crime, and conspiracy theorists widely assert that Ruby killed Oswald as part of an overall plot surrounding the assassination of President Kennedy.

Others have disputed this, arguing that Ruby’s connection with gangsters was minimal at best – and also that Ruby was not the sort to be entrusted with such an act within a high-level conspiracy.

In the 1992 film “Ruby”, Jack Ruby was played by Danny Aiello.

That’s Hollywood.

Here’s some history, for you:

Ruby’s Early Life

Jack Ruby was born Jacob Leon Rubenstein to Joseph Rubenstein and Fannie Turek Rutkowski (or Rokowsky) – both Polish-born, Orthodox Jews – in Chicago, on March 25, 1911.

The fifth of his parents’ eight surviving children, Ruby had a troubled childhood and adolescence growing up in the Maxwell Street area of Chicago, marked by juvenile delinquency and time spent in foster homes.

On June 6, 1922, at age 11, he was arrested for truancy. Ruby eventually skipped school enough times to be sent to the Institute of Juvenile Research.

Back on the street, the young Ruby sold horse-racing tip sheets and various other novelties, then acted as business agent for a local refuse collectors union that later became part of the International Brotherhood of Teamsters.

Military Service

In the 1940s, Ruby frequented race tracks in Illinois and California.

He was drafted in 1943 and served in the Army Air Forces during World War II, working as an aircraft mechanic at bases in the US until 1946. He had an honorable record and was promoted to Private First Class.

Upon his discharge on February 21, 1946, Ruby returned to Chicago.

Ruby in Dallas

In 1947, Ruby moved to Dallas where he and his brothers soon afterward shortened their surnames from Rubenstein to Ruby.

The stated reason for changing the family name was that he and his brothers had opened up a mail order business and feared that some customers would refuse to do business with Jews.

Ruby later went on to manage various nightclubs, strip clubs, and dance halls. Among the strippers Ruby befriended was Candy Barr.

Ruby developed close ties to many Dallas police officers who frequented his nightclubs, where he showered them with large quantities of liquor and other favors.

Cuban Connections

In 1959, Ruby went to Cuba – ostensibly to visit a friend, influential Dallas gambler Lewis McWillie, an associate of Mafia boss Santo Trafficante. Ruby may have met directly with Trafficante on those visits, according to the testimony of British journalist John Wilson-Hudson, who was imprisoned in Cuba at the time.

Trafficante operated major casinos in Cuba, and was briefly imprisoned after Fidel Castro came to power.

The House Select Committee on Assassinations inferred from Ruby’s trip to Cuba and his subsequent trips “…that Ruby was at least serving as a kind of courier on behalf of gambling interests in Cuba.”

Alleged Links to Organized Crime

Ruby was known to have had links with both the police and the Mafia.

In 1946, mobster Tony Accardo allegedly asked Jack Ruby to go to Texas with Mafia associates Pat Manno and Romie Nappi to ensure that Dallas County Sheriff Steve Gutherie would acquiesce to the Mafia’s expansion into Dallas.

The House Select Committee on Assassinations said that Ruby had known restaurateurs Sam and Joseph Campisi since 1947, and had been seen with them on many occasions.

After an investigation of Joe Campisi, the HSCA found:

“While Campisi’s technical characterization in federal law enforcement records as an organized crime member has ranged from definite to suspected to negative, it is clear that he was an associate or friend of many Dallas-based organized crime members, particularly Joseph Civello, during the time he was the head of the Dallas organization. There was no indication that Campisi had engaged in any specific organized crime-related activities.”

Similarly, a PBS Frontline investigation into the connections between Ruby and Dallas organized crime figures reported the following:

“In 1963, Sam and Joe Campisi were leading figures in the Dallas underworld. Jack knew the Campisis and had been seen with them on many occasions. The Campisis were lieutenants of Carlos Marcello, the Mafia boss who had reportedly talked of killing the President.”

A day before Kennedy was assassinated, Ruby went to Joe Campisi’s restaurant. At the time of the Kennedy assassination, Ruby was close enough to the Campisis to ask them to come and see him after he was arrested for shooting Lee Oswald.

James E. Beaird – who claimed to be a poker-playing friend of Jack Ruby – told both The Dallas Morning News and the FBI that Ruby smuggled guns and ammunition from Galveston Bay, Texas to Fidel Castro’s guerrillas in Cuba in the late 1950s.

Beaird said that Ruby “was in it for the money. It wouldn’t matter what side, just [whatever] one that would pay him the most.”

Beaird said that the guns were stored in a two-story house near the waterfront, and that he saw Ruby and his associates load “many boxes of new guns, including automatic rifles and handguns” on a 50-foot military-surplus boat. He claimed that “each time that the boat left with guns and ammunition, Jack Ruby was on the boat.”

Blaney Mack Johnson, an FBI informant, said Ruby was involved in “arranging illegal flights of weapons from Miami” to pro-Castro forces in Cuba in the early 1950s.

Conspiracy Theory

In his memoir “Bound by Honor: A Mafioso’s Story”, Bill Bonanno, son of New York Mafia boss Joseph Bonanno, stated that several Mafia families had longstanding ties with anti-Castro Cubans through the Havana casinos operated by the Mafia before the Cuban Revolution.

Many Cuban exiles and Mafia bosses disliked Kennedy, blaming him for the failed Bay of Pigs Invasion. They also disliked his brother, the young and idealistic Attorney General Robert Kennedy, who had conducted an unprecedented legal assault on organized crime.

The Mafia were experts in assassination, and Bonanno reported that he recognized the high degree of involvement of other Mafia families when Ruby killed Oswald, since Bonanno was aware that Ruby was an associate of Chicago mobster Sam Giancana.

Four years prior to the assassination of President Kennedy, Ruby went to see a man named Lewis McWillie in Cuba. Ruby considered McWillie, who had previously run illegal gambling establishments in Texas, to be one of his closest friends.

At the time Ruby visited him, in August 1959, McWillie was supervising gambling activities at Havana’s Tropicana Club. Ruby told the Warren Commission that his August trip to Cuba was merely a social visit at the invitation of McWillie.

The House Select Committee on Assassinations would later conclude that Ruby “…most likely was serving as a courier for gambling interests.”

The committee also found “circumstantial,” but not conclusive, evidence that “…Ruby met with [Mafia boss] Santo Trafficante in Cuba sometime in 1959.”

In his book, “Contract on America”, David Scheim presented evidence that Mafia leaders Carlos Marcello, Santo Trafficante, Jr. and Jimmy Hoffa ordered the assassination of President Kennedy. Scheim cited in particular a 25-fold increase in the number of out-of-state telephone calls from Jack Ruby to associates of these crime bosses in the months preceding the assassination.

According to Vincent Bugliosi, both the Warren Commission and the House Select Committee on Assassinations determined all of these calls were related to Ruby seeking help from the American Guild of Variety Artists in a matter concerning two of his competitors.

The House Select Committee on Assassinations report stated “…that most of Ruby’s phone calls during late 1963 were related to his labor troubles. In light of the identity of some of the individuals with whom Ruby spoke, however, the possibility of other matters being discussed could not be dismissed.”

The Kennedy Assassination

President John F. Kennedy was assassinated on November 22, 1963, in Dallas, Texas – ostensibly shot by Lee Harvey Oswald.

White House correspondent Seth Kantor – who was a passenger in the President’s motorcade – told the Warren Commission that he went to Parkland Hospital about an hour after President Kennedy was shot. It was at Parkland Hospital that Kennedy received medical care after the shooting.

Kantor said that as he was entering the hospital, he felt a tug on his coat. He turned around to see Jack Ruby, who called him by his first name and shook his hand. Kantor said that he had become acquainted with Ruby when Kantor was a reporter for the Dallas Times Herald newspaper.

According to Kantor, Ruby asked him if he thought that it would be a good idea for him to close his nightclubs for the next three nights because of the tragedy, and Kantor responded that he thought that doing so would be a good idea.

It has been suggested that Ruby might have been involved in tampering with evidence while at the hospital.

Ruby would later deny he had been at Parkland Hospital, and the Warren Commission decided to believe Ruby rather than Kantor.

However, in 1979, the House Select Committee on Assassinations reversed the Warren Commission’s judgement, stating: “While the Warren Commission concluded that Kantor was mistaken [about his Parkland encounter with Ruby], the Committee determined he probably was not.”

Goaded by the Warren Commission’s dismissal of his testimony, Seth Kantor researched the Ruby case for years.

In a later published book called “Who Was Jack Ruby?”, Kantor wrote:

“The mob was Ruby’s “friend.” And Ruby could well have been paying off an IOU the day he was used to kill Lee Harvey Oswald. Remember: “I have been used for a purpose,” the way Ruby expressed it to Chief Justice Warren in their June 7, 1964 session. It would not have been hard for the mob to maneuver Ruby through the ranks of a few negotiable police [to kill Oswald].”

Witness Wilma Tice also said that she saw Jack Ruby at Parkland Hospital during the time Kennedy was being treated there.

Called to testify before the Warren Commission, Tice said that she received an anonymous phone call from a man telling her “…that it would pay me to keep my mouth shut.”

The Murder of Lee Harvey Oswald

Ruby (also known as “Sparky,” from his old boxing nickname “Sparkling Ruby”) was seen in the halls of the Dallas Police Headquarters on several occasions after the arrest of Lee Harvey Oswald on November 22, 1963.

Newsreel footage from WFAA-TV (Dallas) and NBC shows Ruby impersonating a newspaper reporter during a press conference at Dallas Police Headquarters on the night of the assassination.

District Attorney Henry Wade briefed reporters at the press conference, telling them that Lee Oswald was a member of the anti-Castro Free Cuba Committee. Ruby was one of several people there who spoke up to correct Wade, saying: “Henry, that’s the Fair Play for Cuba Committee,” a pro-Castro organization.

Some speculate that Ruby may have hoped to kill Oswald that night at the police station press conference. Ruby told the FBI (a month after his arrest for killing Oswald) that he had his loaded snub-nosed Colt Cobra .38 revolver in his right-hand pocket during the press conference.

Two days later on Sunday, November 24 – after driving into town and sending a money order to one of his employees – Ruby walked to the nearby police headquarters and made his way to the basement.

At 11:21 am CST – while authorities were preparing to transfer Oswald by private car from the police basement to the nearby county jail – Ruby stepped out from a crowd of reporters and fired his .38 revolver into Oswald’s abdomen, fatally wounding him.

The shooting was broadcast live nationally, and millions of television viewers witnessed it. There is some evidence that Ruby’s actions were on a whim, as he left his favorite dog, Sheba, in the car before shooting Oswald.

However, the House Select Committee on Assassinations in its 1979 Final Report stated:

“…Ruby’s shooting of Oswald was not a spontaneous act, in that it involved at least some premeditation. Similarly, the committee believed it was less likely that Ruby entered the police basement without assistance, even though the assistance may have been provided with no knowledge of Ruby’s intentions…”

The committee was troubled by the apparently unlocked doors along the stairway route and the removal of security guards from the area of the garage nearest the stairway shortly before the shooting.

Aftermath of the Shooting

When Ruby was arrested immediately after the shooting, he told several witnesses that he had helped the city of Dallas “redeem” itself in the eyes of the public, and that Oswald’s death would spare “…Mrs. Kennedy the discomfiture of coming back to trial.”

Within hours of Ruby’s arrest for shooting Oswald, a telegram was received at the Dallas city jail in support of Ruby, under the names of Hal and Pauline Collins. In one of the Warren Commissions exhibits, Hal Collins is listed as a character reference by Ruby on a Texas liquor license application.

At the time of the shooting Ruby said he was taking phenmetrazine, a central nervous system (CNS) stimulant.

Ruby’s explanation for killing Oswald would be “exposed … as a fabricated legal ploy”, according to the House Select Committee on Assassinations.

In a private note to one of his attorneys, Joseph Tonahill, Ruby wrote: “Joe, you should know this. [My first lawyer] Tom Howard told me to say that I shot Oswald so that Caroline and Mrs. Kennedy wouldn’t have to come to Dallas to testify. OK?”

Another motive was put forth by Frank Sheeran (allegedly a hitman for the Mafia), in a conversation he had with the then-former Teamsters boss Jimmy Hoffa.

During the conversation, Hoffa claimed that Ruby was assigned the task of coordinating police officers who were loyal to Ruby, to murder Oswald while he was in their custody. As Ruby evidently mismanaged the operation, he was given a choice to either finish the job himself, or forfeit his life.

Prosecution and Conviction

After Ruby’s arrest, he asked Dallas attorney Tom Howard to represent him. Howard accepted, and asked Ruby if he could think of anything that might damage his defense. Ruby responded that there would be a problem if a man by the name of “Davis” should come up. Ruby told his attorney that he “…had been involved with Davis, who was a gunrunner entangled in anti-Castro efforts.”

Davis was identified years later — after research by journalist Seth Kantor — as being Thomas Eli Davis III, a CIA-connected “soldier of fortune.”

Ruby later replaced attorney Tom Howard with prominent San Francisco defense lawyer Melvin Belli – who agreed to represent Ruby pro bono (free of charge).

Some observers thought that the case could have been disposed of as a “murder without malice” charge (roughly equivalent to manslaughter), with a maximum prison sentence of five years.

Belli attempted to prove, however, that Ruby was legally insane and had a history of mental illness in his family. The latter was true, as his mother had been committed to a mental hospital years before.

On March 14, 1964, Ruby was convicted of murder with malice – for which he received a death sentence.


During the six months following the Kennedy assassination, Ruby repeatedly asked, orally and in writing, to speak to the members of the Warren Commission.

The commission initially showed no interest.

Only after Ruby’s sister Eileen wrote letters to the commission – and her letters became public – did the Warren Commission agree to talk to Ruby.

In June 1964, Chief Justice Earl Warren, then-Representative Gerald R. Ford of Michigan, and other commission members went to Dallas to see Ruby.

Ruby asked Warren several times to take him to Washington D.C., saying “my life is in danger here” and that he wanted an opportunity to make additional statements. He added: “I want to tell the truth, and I can’t tell it here.”

Warren told Ruby that he would be unable to comply, because many legal barriers would need to be broken and public interest in the situation would be too heavy. Warren also told Ruby that the commission would have no way of protecting him, since it had no police powers.

Following Ruby’s March 1964 conviction for murder with malice, Ruby’s lawyers, led by Sam Houston Clinton, appealed to the Texas Court of Criminal Appeals, the highest criminal court in Texas.

Ruby’s lawyers argued that he could not have received a fair trial in the city of Dallas because of the excessive publicity surrounding the case.

Not long before Ruby died, according to an article in the London Sunday Times, he told psychiatrist Werner Teuter that the assassination was “an act of overthrowing the government” and that he knew “who had President Kennedy killed.” He added: “I am doomed. I do not want to die. But I am not insane. I was framed to kill Oswald.”

Eventually, the appellate court agreed with Ruby’s lawyers for a new trial, and on October 5, 1966, ruled that his motion for a change of venue before the original trial court should have been granted.

Ruby’s conviction and death sentence were overturned.

The Death of Jack Ruby

Arrangements were underway for a new trial to be held in February 1967 in Wichita Falls, Texas, when on December 9, 1966, Ruby was admitted to Parkland Hospital in Dallas, suffering from pneumonia. A day later, doctors realized he had cancer in his liver, lungs, and brain.

Ruby died of a pulmonary embolism, secondary to bronchogenic carcinoma (lung cancer), on January 3, 1967 at Parkland Hospital – where Oswald had died, and where President Kennedy had been pronounced dead after his assassination.

He was buried beside his parents in the Westlawn Cemetery in Norridge, Illinois.

And perhaps took the whole truth behind the affair with him.

That’s it, for this one.
