What is today a trite proverb — that behind every great man is a great woman — was once a radical idea. When deployed by second-wave feminists, it invoked systemic, gendered self-sacrifice, generations of housewives, caretakers, and clerical workers whose labor and support propped up countless powerful men. Eva Hagberg’s When Eero Met His Match: Aline Louchheim Saarinen and the Making of an Architect (Princeton University Press, 2022) is ostensibly about the great woman, critic and publicist Aline Louchheim, behind a great man, architect Eero Saarinen. We have Louchheim to thank, Hagberg argues, for Saarinen’s enduring influence on mid-century architecture, and When Eero Met His Match makes a strong case for “how her work — her words — are just as integral to Saarinen’s legacy as the buildings themselves.”
