While decoupling fragrance and gender may seem like a modern idea, art historian Jessica Murphy points out that it is really an old idea.

For the majority of it history, fragrance has known no gender. She sees the industrial revolution and resulting commercialization of fragrance as the period when it came to be partitioned into two genders. Before this time, fragrance was lawless — the scent of a rose or a strong musk was open to all.
