Janet Flanner

For the next 50 years, Flanner wrote nearly 700 installments of her Letter from Paris for The New Yorker under the name Genêt. To prepare for the column, she read at least eight French newspapers each day, clipping out interesting items and then meeting with people to follow up on them. She also wrote profiles and essays for the magazine, including a three-part piece on Hitler several years before the start of WWII.
