Biographical Note

Isabelle Phillips Math?e (1897-1968) was the daughter of James Phillips and Carrie Fulton Phillips, the paramour of Warren G. Harding. Born in Marion, Ohio, she was educated in Germany from 1911-1914, and subsequently in a New York State boarding school during the First World War. On September 27, 1919, she married William Helmuth Math?e (1893-1976). Math?e was born Helmuth Wilhelm Math?e in Aachen, Germany. He departed Germany on July 29, 1914, three days before that country's entry into the war, and arrived in the United States to study agriculture at Cornell University. After studying at Cornell, he was a student at the University of Wisconsin, Madison, 1915-1916. In 1916 he became a farm superintendent in Florence, Wisconsin, where he worked during the war, followed by a banking position at Ladenburg Thalmann of New York in 1918. After his marriage to Isabelle, they resided with the Phillipses in Marion, Ohio. Their son was born in Ohio in 1920 and William became a naturalized United States citizen in 1921. The Math?es moved to Zurich, Switzerland, in 1922 where William held the position of commercial attach? and vice consul for several years. In 1927, he began a lengthy career with Johnson & Johnson in New Jersey, followed by other management positions at other companies in New Jersey, New York, Wisconsin, and Illinois. The Math?es opened an antique store in 1960 in Genoa City, Wisconsin. When the Warren G. Harding-Carrie Fulton Phillips correspondence became known to the public in 1964, the Math?es were drawn into newspaper stories and lengthy legal proceedings to determine rights, ownership, and disposition of the papers. After Isabelle passed away in 1968, it fell to William Math?e and their heirs to complete the legal work.

Scope and Content Note

The Phillips / Math?e Collection spans the years 1913-2014, however only one item dates after 1972. The collection is a companion to the Warren G. Harding-Carrie Fulton Phillips Correspondence, a collection also held by the Manuscript Division. The papers center on Isabelle Phillips Math?e, daughter of Carrie Fulton Phillips, the paramour of Warren G. Harding, and Isabelle's husband, William Helmuth Math?e. Included are photographs of Isabelle and her mother, Carrie, letters from President Harding to William Helmuth Math?e, and correspondence, legal papers, and news clippings concerning the discovery in 1964 of the correspondence of Harding with Carrie Phillips and the subsequent legal proceedings. The final folder contains a statement from the four grandsons of Isabelle and William Math?e conveying their thoughts about these papers and the Warren G. Harding-Carrie Fulton Phillips Correspondence.
