Fen Montaigne is a journalist, author, and editor who specializes in the environment, science, and international affairs. A Pulitzer Prize finalist, Guggenheim fellow, and former foreign correspondent who has written extensively for National Geographic magazine, Montaigne has authored or co-authored six books. He helped launch and is senior editor of Yale Environment 360, an online magazine that has won a host of awards and attracts 2.5 million visitors a year.

Fen’s latest book is the critically acclaimed Fraser’s Penguins: A Journey to the Future in Antarctica. The book tells the story of Bill Fraser, a U.S. ecologist who has done research in Antarctica for 40 years, documenting the decline of sea ice-dependent Adélie penguins as the Antarctic Peninsula has warmed faster than any place on earth. Fen spent nearly five months in Antarctica as a member of Fraser’s field team. The Sunday New York Times Book Review said, “Fraser’s Penguins leaves one feeling exhilarated — by these remarkable creatures, the landscape they inhabit, and the scientists who’ve devoted their lives to studying both.” The book was excerpted in The New Yorker and Fen appeared on “The Colbert Report” to discuss Fraser’s Penguins. He lectures on Antarctic voyages run by Lindblad and National Geographic.

Fen worked for 20 years as a newspaper reporter, primarily for The Philadelphia Inquirer, where he served as the paper’s Moscow correspondent during the collapse of the Soviet Union. Fen then became a freelance writer for 12 years, traveling to every continent but Australia as he reported on the environment and international affairs. A graduate of the University of Virginia, Fen also has written for Outside, Smithsonian, and The Wall Street Journal, among other publications.
