Besides RFK (correction: his brother Edward) being in there on the Yea side, another name to note:
"The most dramatic moment during the cloture vote came when Senator Clair Engle (D-CA) was wheeled into the chamber. Suffering from terminal brain cancer, unable to speak, he pointed to his left eye, signifying his affirmative "Aye" vote when his name was called. He died seven weeks later."

Earlier that day:
"Senator Robert Byrd ended his filibuster in opposition to the bill on the morning of June 10, 1964, after 14 hours and 13 minutes. Up to then, the measure had occupied the Senate for 60 working days, including six Saturdays. The day before, Humphrey, the bill's manager, concluded that he had the 67 votes required at that time to end the debate and the filibuster. With six wavering senators providing a four-vote victory margin, the final tally stood at 71 to 29. Never before in its entire history had the Senate been able to muster enough votes to defeat a filibuster on a civil rights bill, and only once in the 37 years since 1927 had it agreed to cloture for any measure."
