George Catlett Marshall Jr. was an American statesman and soldier. He was Chief of Staff of the United States Army under presidents Franklin D. Roosevelt and Harry S. Truman, and served as Secretary of State and Secretary of Defense under Truman. He was hailed as the "organizer of victory" by Winston Churchill for his leadership of the Allied victory in World War II. After the war, in his service as Secretary of State, Marshall advocated a significant U.S. economic and political commitment to post-war European recovery, including the Marshall Plan that bore his name. In recognition of this work, he was awarded the Nobel Peace Prize in 1953.
Herodotus was a Greek historian who was born in Halicarnassus in the Persian Empire and lived in the fifth century BC , a contemporary of Thucydides, Socrates, and Euripides. He is often referred to as "The Father of History", a title first conferred by Cicero; he was the first historian known to have broken from Homeric tradition to treat historical subjects as a method of investigation—specifically, by collecting his materials systematically and critically, and then arranging them into a historiographic narrative.
