Who was St. Patrick?

Who was St. Patrick that he should have his own holiday? This article by Mark Driscoll gives us an answer. St. Patrick was "one of the greatest missionaries who ever lived."

"Patrick gave his life to the people who had enslaved him until he died at 77 years of age. He had seen untold thousands of people convert as between 30-40 of the 150 tribes had become substantially Christian. He had trained 1000 pastors, planted 700 churches, and was the first noted person in history to take a strong public stand against slavery."
