THE NEW YORK TIMES BOOK REVIEW – August 20, 2023: The issue features “never before told” narrative histories including a tale of the female botanists who surveyed the Grand Canyon in 1938, a recent biography of the 19th-century “abortionist of Fifth Avenue” and the book on this week’s cover: Prudence Peiffer’s “The Slip,” which brings into focus a thriving artistic community that existed at the southernmost tip of Manhattan in the 1950s and ’60s.

They Overcame Hazards — and Doubters — to Make Botanical History

In a black-and-white photograph from 1938, two women and four men sit in a boat looking at the camera. One woman wears a white dress and hat; the other wears slacks and a blouse. Three of the men are shirtless; two wear pith helmets.

In Melissa Sevigny’s “Brave the Wild River,” we meet the two scientists who explored unknown terrain — and broke barriers.
