Object Lessons is a series of short, beautifully designed books about the hidden lives of ordinary things. Our sense of smell is crucial to our survival. We can smell fear, disease, food. Fragrance is also entertainment. We can smell an expensive bottle of perfume at a high-end department store. Perhaps it reminds us of our favorite aunt. A memory in a bottle is a powerful thing. Megan Volpert'sPerfumecarefully balances the artistry with the science of perfume. The science takes us into the neurology of scent receptors, how taste is mostly smell, the biology of illnesses that impact scent sense, and the chemistry of making and copying perfume. The artistry of perfume involves the five scent families and symbolism, subjectivity in perfume preference, perfume marketing strategies, iconic scents and perfumers, why the industry is so secretive, and Volpert's own experiments with making perfume. Object Lessons is published in partnership with an essay series inThe Atlantic.
