Thandiwe Newton is her name. Her mother, a Zimbabwean princess, and her father, a lab technician from Cornwall, England, named her Thandiwe, meaning "beloved" in Zulu.
The 'w' first disappeared from her name in Catholic school, forming a more anglicized "Thandie." At school she was "made to feel like an in-house missionary project," writes Diana Evans in a cover story for British Vogue.
In Newton's first film, the 'w' was "carelessly missed" in her credit; she was credited the same way in subsequent roles, but no more. The Westworld star said she is now grateful "to not be complicit in the objectification of Black people as 'others'." Her Vogue photo shoot involved clothes that reflected her European and African heritage, and the magazine cover reads "Thandiwe Newton." "That's my name. It's always been my name. I'm taking back what's mine," Newton said. Read more at British Vogue.
