Thomas died June 2, 2019, in White Plains, N.Y., after a long illness. He was 82.
He attended Milton Academy, Princeton, and Columbia University, where he earned a bachelor’s degree in American history. He also pursued graduate studies at Columbia.
From 1956 to 1959 he served in the Army 82nd Airborne Division. For 20 years he helped manage the library promotion department at Harper & Row publishers, after which he formed his own company, Pro Am Music Resources.
Under that imprint he published many books by musicians and music historians, as well as his own music and mythology. His encyclopedic knowledge of all things related to classical music, philosophy, and great literature was celebrated and cherished by his family and friends.
Thomas was predeceased by his partner of 30 years, Karen R. Baker, in 2017. He is survived by his children, Abigail Lewis Stovman, Peter Sloan Lewis, and Emily Ivins Lewis Fucheck; grandchildren Maxwell and Sophia Fucheck and Brandon Stovman; sister Dianne Lewis Bonney; former wife of 20 years Elizabeth Sloan Lewis; sons-in-law David Fucheck and Blake Stovman; and daughter-in-law Julianna Schley. The class extends its deepest sympathy to them all.
