  We examine the life and legacy of pioneering Vietnamese computer scientist
B\`ui Tuong Phong, whose shading and lighting models turned 50 last year. We
trace the trajectory of his life through Vietnam, France, and the United
States, and its intersections with global conflicts. Crucially, we present
definitive evidence that his name has been cited incorrectly over the last five
decades. His family name is B\`ui Tuong, not Phong. By presenting these facts
at SIGGRAPH, we hope to collect more information about his life, and ensure
that his name is remembered correctly in the future.
  Correction: An earlier version of the article speculated his family name was
B\`ui. We have since received definitive confirmation that his family name was
B\`ui Tuong. We have amended the text accordingly.
