When a person immigrates, he or she moves to a new country. During the great wave of immigration between 1880 and 1924, over 25 million Europeans immigrated to the United States.
Many immigrants make significant contributions to their adopted countries. Consider Albert Einstein, the greatest physicist of the twentieth century, who immigrated to America from Germany, or the Russian-born New Yorker Irving Berlin, who wrote some of the most popular songs in the American songbook, including “White Christmas” and “God Bless America." The word immigrate comes from the Latin imigrare, which means “to move in.”
