“Mademoiselle Eiffel,” by Aimie K. Runyan book event: 7 p.m. Tuesday, Trident Booksellers & Café, 940 Pearl St., Boulder. Claire Eiffel, the beautiful, brilliant eldest daughter of the illustrious architect Gustave Eiffel, is doted upon with an education envied by many sons of the upper classes and entirely out of the reach of most daughters. Claire’s idyllic childhood ends abruptly when, at 14, her mother passes away. She learns her father’s architectural trade and becomes indispensable to his work. But when his bright young protégé, Adolphe Salles, takes up more of Gustave’s time, Claire resents being pushed aside. Slowly, the animosity between Claire and Adolphe turns to friendship … and then to something more. After their marriage in 1885 preserves the Eiffel legacy, they are privileged by the biggest commission of Eiffel’s career — a great iron tower dominating the 1889 World’s Fair to demonstrate the leading role of Paris in the world of art and architecture. tridentcafe.com.
