What is the impact of Rillieux work today?
His invention is considered to be one of the earliest examples of chemical engineering, and it remains the basis for all modern forms of industrial evaporation. The basic idea of Rillieux's evaporator is still used today to produce sugar, as well as other products such as condensed milk and freeze- dried foods.

She and her husband invented a dip-and-read paper strip that greatly simplified the diagnosis of the disease and paved the way for home test kits.
When was the first insulin pump invented?
The first wearable insulin pump, known as the 'blue brick' and later the 'autosyringe,' was designed by Dean Kamen in 1976 and led to the introduction of insulin pump therapy in the same year (57).
