The VW was hand measured by Sutherland's students: Jim Clark (of SGI/Netscape fame), Bui-Tui Phong (of Phong shading fame), Raphel Rom (of Catmull-Rom spline fame), and Robert McDermott (of Vegreville Egg fame). (I just listed some highlights of careers, they all accomplished much more!)
A first hand account of the model creation is preserved by Mr. McDermott on page 7 of the Fall 2003 edition of The Utah Teapot [2] (the aptly named University of Utah School of Computing quarterly newsletter).
The CS Dept. at the U of Utah has such a storied history, especially rich in fundamental computer graphics research [3]. Growing up in proximity to it definitely shaped my career path.
