Packer was born in California around 1960.[1] His parents taught at Stanford University: his mother, Nancy Packer (née Huddleston), was a Wallace Stegner Fellow in the Creative Writing Program and later professor of English, and his father, Herbert L. Packer, was a distinguished professor of law, and the author of numerous books and articles. Packer's maternal grandfather, George Huddleston, Sr., had served eleven successive terms (1915–1937) representing Alabama's 9th congressional district in the U.S. House of Representatives. His uncle, George Huddleston, Jr., succeeded to his father's seat in the House of Representatives from 1954 to 1964.[2] Packer's sister, Ann Packer, also is a writer. Their father's background was Jewish and their mother's Christian.[3] In a 2022 talk for House of SpeakEasy's Seriously Entertaining program, Packer shared that his father took his own life when he (Packer) was twelve years old, calling it "the big event of my childhood."[4]

The Unwinding: An Inner History of the New America focuses on the ways that America changed in the years between 1978 and 2012.

In 2019, Packer released a book titled Our Man: Richard Holbrooke and the End of the American Century, a full-scale scholarly biography of Richard Holbrooke, one of the most influential U.S. diplomats of the late 20th Century.[9] Our Man was a finalist for the 2020 Pulitzer Prize Finalist in Biography.[10]
