The Aug. 28, 1955 lynching of Emmett Till and the subsequent acquittal of his murderers by an all-white Mississippi jury were among the American civil rights movement’s pivotal events.

For a certain indecent number of people, however, the passion of the 14-year-old youth — alleged to have flirted with a white woman — was to be mourned only insofar as it confirmed the menace that insatiable Negro libidos posed to southern way of life.

Further to that end, the months following Emmett Till’s death brought to the headlines the formerly obscure* July 2, 1945 hanging of an American G.I. in Italy: Emmett’s father, Louis Till.

The violent Louis Till ruined his marriage to Emmett’s mother Mamie shortly after his son’s birth. Repeatedly violating her restraining order eventually landed Till pere before a judge, who gave him a choice between hard time and enlistment. Till joined the U.S. Army.

In 1945, he was court-martialed for murdering an Italian woman and raping two others. His execution near Pisa — he’s buried in Europe in the Oise-Aisne American Cemetery, the same final resting place as Eddie Slovik — was the no-account end of a no-account man for many years thereafter. Mamie Till said that she wasn’t even told what happened to her ex-husband, and was stonewalled when she sought information.

By the end of 1955, everyone knew.

In Jim Crow’s backlash against nationwide condemnation of the Till lynching, Louis Till came back to life in newsprint all that autumn to visit the sins of the father upon his late son: here was the mirror of the young predator all grown up, violating Italian women. Mississippi’s white supremacist senators used their rank to obtain his army file, and leaked it to reporters.

According to Davis Houck and Matthew Grindy’s study of the Mississippi media’s conflicting reactions to the events of 1955, “Louis Till became a most important rhetorical pawn in the high-stakes game of north versus south, black versus white, NAACP versus White Citizens’ Councils.”

The pawn’s sacrifice did not figure in the endgame.

Crude attempts to impose blood guilt for Louis Till’s crimes aside, Clenora Hudson-Weems argues in her Emmett Till: The Sacrificial Lamb of the Civil Rights Movement that it was Emmett Till’s shocking death that catalyzed the civil rights movement — that the horrifyingly mutilated face at his open-casket funeral and the insouciant confession of his killers once they had been acquitted shook southern blacks and northern whites alike so profoundly as to dispel any confidence that legal briefs or political incrementalism could grapple with America’s race problem. Civil rights lion Joyce Ladner was an 11-year-old Mississippi girl when Emmett Till was lynched; she would tell Hudson-Weems of the shock it delivered in her world coming on the heels of the Brown v. Board of Education ruling desegregating schools.

A very important thing is that it followed the Supreme Court decision in 1954. It’s like the Whites said that they don’t care what rights we were given … So when the spark came in Mississippi to sit in the public library, for example, people who participated had been incensed by the Till incident and were just waiting for the spark to come. The Till incident was the catalyst.

On December 1, 1955, Rosa Parks refused to give up her seat to a white man on a Montgomery, Alabama bus, launching the famous bus boycott. “I thought of Emmett Till and I just couldn’t go back,” Parks said later.

Emmett Till’s body was exhumed for autopsy and DNA testing in 2005, in part to dispel the old story first promulgated by the attorneys who defended Till’s murderers — that the body wasn’t Emmett Till’s at all. On the corpse’s finger was a ring inscribed with the initials of his father: L.T.

* Louis Till did have one small claim to fame prior to his son’s murder: the fascist poet Ezra Pound chanced to be imprisoned with Till; he mentions the later-famous execution in his Pisan Cantos:

Till was hung yesterday
