He will be missed.

McWORTER William A. McWorter was born July 15, 1932 and passed in
Delaware, Ohio on October 22, 2009. He leaves a son, William A. McWorter
III; a sister, Shirley Moss; and a loving extended family. William was a
professor of Mathematics at The Ohio State University. He is best known
for his extensive work and contributions to the study of Fractals. He
loved acting, golf, and engaging in mind bending conversations. Please
join us to remember William 5:30-7 p.m. at Damon's, 3025 Olentangy River
Rd., Wednesday, November 11, 2009.
Before the Mandelbrot set there was
Dr. McWorter's Byte article.
Suddenly turtles became a way to make pretty fractals.
The death of the first American fractist
should be observed.
That he was Black isn't often mentioned or that he was
in a generation where black scholars were rare
in Mathematics as well as other fields.
We will miss the man who first told us about fractal tiles
and who found his share of new and unknown ones.
I met him when I discovered a new way to make one of his tiles
from a completely different approach.
We became friends and worked on what we called "fractal holes".
He found a way to find fractal sets inside the borders
of other fractal sets.
He introduced me to Dekking's work on fractal substitutions.
I consider him and Dr Edgar who worked with him
as my fractal mentors,
although I have never met either of them.
My personal wish is that the editors of Byte hadn't
made publishing so hard for him, as the world would
have been served by seeing his fractals holes
and his Penrose tiles.
He also did some work on permutation groups as associated
with marriage laws in primitive tribes which he didn't like to talk about.
He was a master of programming sequential path fractals
and freely gave and taught others in a selfless manner.
He was an example of all that was good in the fractal culture.
One tends to forget the work done on fractals before Mandelbrot rebranded the field.
