What famous historical figure said "The only thing we have to fear is fear itself"?

After taking the Presidential oath of office, Franklin D. Roosevelt proceeded to deliver his 1,883-word, 20 minute-long inaugural address, best known for his famously pointed reference to "fear itself" in one of its first lines: "So, first of all, let me assert my firm belief that the only thing we have to fear is...fear itself — nameless, unreasoning, unjustified terror which paralyzes needed efforts to convert retreat into advance."

The speech was delivered on March 4, 1933. His inaugural address took on an unusually solemn, religious quality. And for good reason—by 1933 the depression had reached its depth.

Roosevelt was born on January 30, 1882, Hyde Park, New York, U.S.A. and became the 32nd president of the United States (1933–45). The only president elected to the office four times, Roosevelt led the United States through two of the greatest crises of the 20th century: the Great Depression and World War II. In so doing, he greatly expanded the powers of the federal government through a series of programs and reforms known as the New Deal, and he served as the principal architect of the successful effort to rid the world of German National Socialism and Japanese militarism. He died on April 12, 1945, in Warm Springs, Georgia at the age of 63.
