William Rehnquist

William Hubbs Rehnquist (October 1, 1924 - September 3, 2005) was an American lawyer, jurist, and a political figure, who served as an Associate Justice on the Supreme Court of the United States and later as the Chief Justice of the United States. A proponent of a federalism that favored state power, his legacy includes the first limits on Congress's power under the Commerce Clause of the United States Constitution since the 1930s.
Rehnquist was born in Milwaukee, Wisconsin, as William Donald Rehnquist [1] and grew up in the suburb of Shorewood. His father, William Benjamin Rehnquist, was a paper salesman; his mother, Margery Peck Rehnquist, was a translator and homemaker. Rehnquist changed his middle name to Hubbs, his grandmother's maiden name, during his high school years.
Rehnquist's paternal grandparents immigrated separately (although they may have known one another before) from Sweden in 1880. His grandfather Olof Andersson, who changed his surname from the patronymic Andersson to the family name Rehnquist, was born in the province of Värmland and his grandmother was born Adolfina Ternberg in Vretakloster (parish) in Östergötland.

Rehnquist is one of two Chief Justices of Swedish descent, the other being Earl Warren, who had Norwegian-Swedish ancestry.

Rehnquist's maternal lineage traces back via New York to the Pilgrims and other early New England settlers.

Rehnquist married Natalie "Nan" Cornell on August 29, 1953. She died on October 17, 1991, after suffering from ovarian cancer. The couple had three children: James, Janet and Nancy. Janet Rehnquist is a former Inspector General of the Department of Health and Human Services.
