Alison Maria Krauss was born in Decatur, Illinois, to Fred and Louise Krauss. Her father was a German immigrant who came to the United States in 1952 at age 12, and taught his native language while he earned a doctorate in psychology. He later went into the business of real estate. Her mother, an American of German and Italian descent, is the daughter of artists, and works as an illustrator of magazines and textbooks. Fred and Louise met while they were studying at the University of Illinois at Urbana–Champaign. After a brief residence in nearby Decatur, the family settled in Champaign, where Krauss was raised with her older brother, Viktor.
