Lyndon B. Johnson is one of the most recent US presidents to be featured in today's IQ list, which is why he is one of the rare ones to have a full-color portrait picture. He was often referred to in the media by his initials, LBJ. He served as the 36th President of the United States, for a single term, between the years of 1963 and 1969.
He became president after his short stint as vice president, which lasted from 1961 to 1963. He was a member of the Democratic party, originally active in the state of Texas. He also served as a United States Representative in the Senate. He is one of only four people in the US that have served in all four types of federally elected positions.
