Fran Hosken (1920-2006), a pioneering Boston-based designer and feminist, is now largely unknown. One of the first women to earn a degree from the Harvard Graduate School of Design, Hosken knew and corresponded with the famed modernist architects of her day. She served in the Coast Guard, ran her own small business, built an important photographic archive, and later worked as an influential campaigner for women’s reproductive and civil rights across the globe. She encountered discrimination, chauvinism, misunderstandings, and business failures too. These mundane and thwarting stumbling blocks are preserved in her letters and underpin her courageous work.
