D ora Voigt de Assis is a Brazilian heiress and one of the largest individual shareholders of WEG, a major multinational company that is a global leader in the production of electric motors. She is one of three grandchildren of Werner Ricardo Voigt, one of the three co-founders of WEG. The company was founded in 1961 in the southern Brazilian state of Santa Catarina.

WEG has grown from a local manufacturer into a global industrial giant, producing a wide range of electrical equipment, including motors, generators, and transformers, as well as industrial automation systems. The company is publicly traded but remains controlled by the descendants of its three founders. Dora Voigt de Assis, along with her siblings and cousins, inherited a substantial stake in the company. She is not involved in the day-to-day management, and her immense wealth is derived from her passive ownership of this highly successful Brazilian industrial enterprise.
