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.

翻译：本文考察了越南计算机科学先驱裴祥风（B\`ui Tuong Phong）的人生与遗产，其提出的着色与光照模型于去年迎来五十周年。我们追溯了他穿越越南、法国和美国的人生轨迹，及其与全球冲突的交汇点。至关重要的是，我们提供了确凿证据，表明过去五十年来他的名字一直被错误引用。他的姓氏是裴祥（B\`ui Tuong），而非风（Phong）。通过在SIGGRAPH会议上呈现这些事实，我们希望收集更多关于他生平的信息，并确保未来他的名字能被正确铭记。更正：本文早期版本推测其姓氏为裴（B\`ui）。我们现已收到确凿确认，其姓氏为裴祥（B\`ui Tuong）。我们已据此修正文本。
