 Here, Lavoisier's interest in chemistry blossomed having previously trained at the chemical laboratory of Guillaume François Rouelle, and, with the financial security provided by both his and Paulze's family, as well as his various titles and other business ventures, he was able to construct a state-of-the-art chemistry laboratory.Paulze soon became interested in his scientific research and began to actively participate in her husband's laboratory work.As her interest developed, she received formal training in the field from Jean Baptiste Michel Bucquet and Philippe Gingembre, both of whom were Lavoisier's colleagues at the time.
