Patricia Peterson Werre loved the periodic tables. She had a blanket of the elements, a poster of them in her office and a coffee cup depicting them.
Chemistry was her life. Even as a young girl, family lore had it, she concocted various mixtures in the kitchen and more than once sent family members scurrying outside from the smell of her latest creation.
Her passion would serve her later in life when she became a pioneering chemist at Aveda, the Minnesota-based skin care products company, where she was a vice president for research and development.
Peterson Werre died of brain cancer on Jan. 30 at her Stillwater home. She was 61.
She was hired by Aveda founder Horst Rechelbacher in 1989 as a senior chemist and eventually handled oversight of groups that developed products in skin care, hair care, spas and color cosmetics. She also managed the Botanical Research Group, which was responsible for the development of active ingredients for Aveda products.
She encouraged the pursuit of sustainable plant materials that could be used for functional ingredients in Aveda products, said Cindy Angerhofer, Aveda executive director of botanical research and a longtime colleague and friend.
"She always had a positive attitude. It was 'Let's find a way to do it with the Aveda mission in mind,' a way to do things with natural products, plants with green chemistry, things that have a positive impact on the earth or at least avoid a negative impact," Angerhofer said. "Pat would always say, 'It's really wonderful to work at Aveda, and it's really, really hard because you have to be dedicated to doing things a harder way that end up with a better product.' "
Peterson Werre once attached bottles of various motor oils to herself as a mockery of the chemical ingredients in cosmetics and called herself Petro Patty.
