(Note: This interview originally aired back in May.) Our guest on this edition of StudioTulsa is Timothy Dwyer, a writer whose work has appeared in Time, Washingtonian, and TheAtlantic.com. Dwyer is also the chief executive officer of The School Choice Group, an education advisory company, and he's the co-author of an engaging new double biography called "Hissing Cousins: The Untold Story of Eleanor Roosevelt and Alice Roosevelt Longworth." It's a lively and memorable profile of two women -- first cousins who were born (both in 1884) into rival factions of a rich and famous New York family -- whose lives were at the very center of American culture and history throughout the 20th century. As a critic for the Richmond Times-Dispatch has written: "With aplomb, stylish prose, and smart analysis, [co-authors Peyser and Dwyer] synthesize their sources smoothly into an entertaining and educational book. And by vividly blending the personal and the political, [they] tell the cousins' story with insight, humor, empathy, and wisdom. In so doing, they call on the best qualities of their subjects to produce a welcome and absorbing addition to the ever-growing canon of Rooseveltiana."
