John Quincy Adams (1767-1848), was 6th President of the United States and the son of John Adams, the second President. At the age of 14, he received the Congressional appointment to the Court of Catherine the great of Russia.
He was a U.S. Senator; U.S. Minister to France, and U.S. Minister to Britain, where he negotiated the Treaty of Then, ending theWar of 1812.
He was one of the few Presidents to re-enter politics after having served as President, became a Congressman in 1831 and adamantly opposed slavery. Nicknamed the “Hell Hound of Slavery,” he single handily led the fight to lift the Gag Rule which prohibited the discussion of the slavery issue in Congress.

He revealed his convictions and philosophy in the following quotation:

I speak as a man of the world to men of the world; and I say to you; Search the Scriptures! The Bible lis the book of all others, to be read at all ages, and in all conditions of the human life; not to be read once or twice or thrice through, and then laid aside, but to be read is small portions of two or three chapters every day, and never to be intermitted, unless by some overruling necessity.
