At 12:10 a.m. PT on June 5, 1968, Robert F. Kennedy, former U.S. attorney general and New York senator and a candidate for the Democratic presidential nomination addressed campaign workers gathered in the ballroom of the Ambassador Hotel in Los Angeles. Kennedy, who had just won the crucial California primary, thanked his supporters for their hard work, before leaving the podium with his wife Ethel (pregnant with the couple’s 11th child) and a group of untrained bodyguards. Moments later, shots rang out from the hotel’s kitchen as Kennedy and five others were shot by Palestinian national Sirhan Sirhan. Sirhan’s other victims survived, but Kennedy succumbed to his wounds 26 hours later. As we commemorate the anniversary of his death, here are 10 things you may not know about Robert F. Kennedy.
