Taddeo Alderotti, a professor of medicine at the University of Bologna, is credited with developing the fractional distillation, giving him a high reputation both then and now. At the time, this process was mostly used for the distillation of fermented products with high alcohol content, such as wine, but today this process is used in the oil and gas industry and in the chemical synthesis industry.
