1837 Mary Gove Nichols

Mary Sargeant Gove Nichols born in 1810, also known by her pen name Mary Orme, was an American women's rights and health reform advocate, hydrotherapist, vegetarian and writer.
Nichols became a vegetarian around 1837. She was an influential proponent in the natural hygiene movement. She lectured to all-female audiences on anatomy, physiology, and hygiene to relieve women of what she saw as unnecessary physical and mental suffering. She recommended that women exercise daily, breathe fresh air, shower with cold water, avoid the fashionable tight-laced corsets of the day.
