Roseller Lim was the first (and so far only) Senator from Zamboanga.
Roseller Lim served on the Senate between 1955 and 1963. He was appointed Justice
of the Court of Appeals in 1973.
Lim was named the 'Great Filibuster' for delivering a speech for 18 hours and 30
minutes in 1962 during a political reorganization in the Senate to prevent then Senator
Ferdinand Marcos from becoming the Senate President. For the entire duration that
he talked, he had to keep standing, leaning on the podium only when he had to. He
was allowed to take only water, but was prohibited from going to the comfort room.
