Biography

Miller was born in Columbus, Indiana, to Hugh Thomas Miller, a college professor and politician, and Nettie Irwin Sweeney. He had one sister, Elizabeth Clementine Miller (1905–1996), who married Robert Stone Tangeman. He was the grandnephew of William Glanton Irwin. They had three daughters, Margaret Irwin, Catherine Gibbs, and Elizabeth Garr, and two sons, Hugh Thomas II and William Irwin. Margaret was married to Jonathan D. Schiller, co-founder of Boies Schiller Flexner LLP. He had ten grandchildren – Jonathan, Zachary, Joshua, Benjamin, Aaron, Andrew, AnnaCatherine, Katherine, Laura, and Emily.

The Miller House in Columbus, which was designed by Eero Saarinen, was declared a U.S. National Historic Landmark in 2000. After the death of Miller's widow in 2008, the house was donated to the Indianapolis Museum of Art in 2009. The family's Canadian summer home on Lake Rosseau near Windermere, Ontario, was also designed by Saarinen.

Work Miller joined Cummins, the family business, in 1934. He was executive vice president from 1944 to 1947, president from 1947 to 1951, and chairman from 1951 to 1977. He served as a lieutenant in the U.S. Navy in the South Pacific during the Second World War.

Miller served as a Trustee of the Ford Foundation and Yale University, and as a director of Chemical Bank. He established the Irwin-Sweeney-Miller Foundation, which supports numerous charities and institutions—notably, Christian Theological Seminary in Indianapolis and Emma Willard School, a leading girls' preparatory school in Troy, NY. The family's business interests were widespread, and he served at various times as Chairman of Irwin Union Bank in Columbus IN, Union Starch and Refining Company, and Irwin Management Company.

Irwin Management was the family's private wealth-management and services organization, funded from Mr. Miller's large Cummins Engine Co. dividends and the income generated by other holdings. The group managed all of the family's assets except Cummins Engine—which Mr. Miller managed personally, as President and later as Chairman. IMCO, as it was called, was divided into departments for Marketable Securities, Oil and Gas, Real Estate, Venture Capital, Financial Planning and Analysis, and Family Services. The company was staffed by about 20 professionals, many of whom had MBA degrees from the leading graduate business schools (e.g., Harvard, Columbia, Chicago, Carnegie-Mellon, Stanford, Oxford). In addition to financial management, the company provided staff services to assist Mr. Miller's roles in philanthropic, foundation, directorship, and trustee positions. It was considered a high-status firm among MBA students, and there was spirited competition for jobs at IMCO upon graduation.

Rockefeller to run for president in 1968 (and served as national campaign chairman) and in 1972 he supported New York City Mayor John Lindsay's presidential bid.

The award is presented annually to "a lay person who has been a witness, through action in the world, to justice and other values affirmed by Christian faith, and who has demonstrated a commitment to church unity."
