Mark Hertsgaard

[3] He has been a commentator for the public radio programs Morning Edition, Marketplace, and Living on Earth, and taught writing at Johns Hopkins and the University of California, Berkeley.

[4] While compiling a feature article for The New Yorker in 1993, Hertsgaard broke the news that the three surviving members of the Beatles were going to issue previously unreleased music from the group's career, as part of their multimedia Anthology project.

[5] At this time, he was granted rare access to the band's EMI recording archives in London, gaining insight that informed his 1995 book A Day in the Life: The Music and Artistry of the Beatles.

[5] Writing in 2000, Nick Bromell, professor of English at the University of Massachusetts, Amherst and the founding editor of Boston Review, described A Day in the Life as "the best single book on the music of the Beatles".

[7] Hertsgaard also wrote about climate change adaptation in Hot: Living Through the Next Fifty Years on Earth (2011), published by Houghton Mifflin Harcourt.
