André de Ruyter is a South African business executive and author born in 1968. He served as CEO of Eskom, South Africa's state-owned power utility, from 2020 to 2023, during one of the country's most severe energy crises. His memoir *Truth to Power* (2023) chronicles his tumultuous tenure at Eskom, exposing corruption, sabotage, and political interference within the organization. The book combines elements of corporate memoir and investigative exposé, offering insider perspectives on state capture and governance failures in South Africa. De Ruyter's straightforward, unflinching narrative style documents his attempts to reform the troubled utility while facing threats and obstruction from powerful vested interests.
