Martin Luther King Jr. was a Nobel Peace Prize winner who died before the age of 40. He was not quite 5'7" but made a massive impact on U.S. history. It is unlikely Barack Obama would have been elected President in 2008 had Martin Luther King Jr. not advanced the cause of civil rights for African Americans. King's influence and inspiration will be felt for decades to come. On January 15, 2018 we observe Martin Luther King Jr. Day (the day of King's birth).
You can buy books about King with one of these links: Martin's Big Words, an autobiography, and The Essential Writings and Speeches of Martin Luther King Jr. Along with the Nobel Prize he won, we should remember the Montgomery Bus Boycott that King lead starting in 1955 lasting until early 1957. If you get a chance to visit Montgomery, Alabama you should find the bus stop where Rosa Parks refused to give up her seat or the fountain where slaves were once sold. You should also visit the Civil Rights Memorial and learn about an important era in American history.
