Anecdote of one, but I had heard of Phong but not Catmull, actually. (Because I was curious about Phong lighting, so then read the wikipedia article which pointed me to him). Your comment is the first time I'd ever heard of Ed Catmull.

I tried to extract everything that looked like a name from the History section of the Wikipedia article on computer graphics.

I had heard of Bui Tuong Phong, Henri Gouraud, Ivan Sutherland, John Carmack, John Warnock, Martin Newell, and Nelson Max.

I hadn't heard of Arthur Appel, Dave Evans, David Immel, David Pearson, Edwin Catmull, Elizabeth Waldram, Frank Sinden, Fred Parke, James Clark, James Kajiya, Jim Blinn, Ken Knowlton, Maurice Benayoun, Michael Noll, Ralph Baer, Steve Russell, Tom Stockham, Verne Hudson, William Fetter, or William Higinbotham.

I haven't studied computer graphics, other than doing the Raytracing in One Weekend project.

(Oops, I missed people with accented, abbreviated, or uncapitalized names, like Pierre Bézier, David C. Evans, and Paul de Casteljau. I don't think this will change the ratio much, though.)
