Celebrated on February 15, Susan B Anthony Day marks the birthday of one of the United States' most prominent female civil rights leaders. Susan B Anthony Day is a legal observance in some states including California, Florida, New York and Wisconsin. (Massachusetts observes in August and West Virginia in November.)

Susan B Anthony is best known for promoting women's rights and starting up the women's suffrage in the United States. She was born in Adams, Massachusetts, on February 15, 1820, and devoted most her life to anti-slavery and women's rights issues, including the right to vote. In 1920, the "Anthony Amendment" was made to the U.S. constitution, which gave women the right to vote. She was the first American woman to have her likeness on a coin in the U.S.
