Jack Markell

Jack Alan Markell (born November 26, 1960) is an American politician, businessman, and diplomat who served as the 73rd Governor of Delaware from 2009 to 2017. A Democrat, he previously held the position of Delaware State Treasurer for three terms from 1999 to 2009, implementing measures to enhance fiscal responsibility. Following his governorship, Markell represented the United States as Ambassador to the Organisation for Economic Co-operation and Development in 2022 and as Ambassador to Italy and San Marino from August 2023 to January 2025.

Markell, a native of Newark, Delaware, graduated from Brown University with degrees in economics and development studies before earning an MBA from the University of Chicago Booth School of Business. His early career spanned banking at First Chicago, management consulting at McKinsey & Company, and executive roles at Merck and Comcast, providing a foundation in corporate finance and operations that informed his public service. As governor, he prioritized economic recovery amid the Great Recession, achieving the strongest job growth in the First State through investments in education, workforce training, and business incentives, while also advancing reforms in early childhood education and college access for low-income students. These efforts included adopting Common Core standards and expanding data-driven accountability in schools, though they drew opposition from some educators and parents concerned over testing and curriculum mandates.

His father, William Markell, served as an accounting professor at the University of Delaware, contributing to the family's academic orientation. His mother, Elaine "Leni" Markell, worked as a social worker, reflecting a family emphasis on public service. The family was Jewish, aligning with Markell's religious background.

Markell, who is Jewish and Delaware's first Jewish governor, is a member of Congregation Beth Emeth in Wilmington and formerly served on the board of the Jewish Federation of Delaware. He has been honored by organizations such as the Jewish National Fund for his leadership.
