In 1890 P. J. Heawood 35] published a formula which he called the
Map Colour Theorem. But he forgot to prove it. Therefore the world
of mathematicians called it the Heawood Conjecture. In 1968 the
formula was proven and therefore again called the Map Color
Theorem. (This book is written in California, thus in American
English. ) Beautiful combinatorial methods were developed in order
to prove the formula. The proof is divided into twelve cases. In
1966 there were three of them still unsolved. In the academic year
1967/68 J. W. T. Youngs on those three cases at Santa Cruz. Sur
invited me to work with him prisingly our joint effort led to the
solution of all three cases. It was a year of hard work but great
pleasure. Working together was extremely profitable and enjoyable.
In spite of the fact that we saw each other every day, Ted wrote a
letter to me, which I present here in shortened form: Santa Cruz,
March 1, 1968 Dear Gerhard: Last night while I was checking our
results on Cases 2, 8 and 11, and thinking of the great pleasure we
had in the afternoon with the extra ordinarily elegant new solution
for Case 11, it seemed to me appropriate to pause for a few minutes
and dictate a historical memorandum. We began working on Case 8 on
10 October 1967, and it was settled on Tuesday night, 14 November
1967."
