Frank Church (D-ID)
Mark Hatfield (R-OR)Paul Wellstone (D-MN)Paul Simon (D-IL)Jacob Javits (R-NY)J. William Fullbright (D-AR)
Howard Metzenbaum (D-OH)William Proxmire (D-WI)
Eugene McCarthy (D-MN)
Hubert Humphrey (D-MN)

Alan Simpson (R-WY)
Mike Mansfield (D-MT)
Daniel Patrick Moynihan (D-NY)
Warren Rudman (R-NH)
Henry Clay
Danial Webster
Arthur Vandenberg
Richard Russell (even though he was a segregationist racist)

And the Senate in 2000 oddly enough apparently adopted a
resolution which reminds us of these worthies:
Robert Taft (not one of my personal favorites because he was an isolationist protectionist but whatever)
Robert LaFollette
Robert Wagner
