In Loving Memory of Robert Kaplan
1933-2021

When asked how he would like to be remembered, Kaplan hesitated. “[In Desargues Theorem,] you have a point of view, three … lines, and two triangles, seen from this point of view, thus they are perspective from this point. And if they are perspective from a point, … then they are perspective of a line.” He interrupts himself: “I’m actually answering your question, believe it or not. That (Desargues) theorem has ten points in it: the point of view, the three vertices of the first triangle, the three vertices of the second triangle, … plus the three points where the paired sides meet. … Any one of those ten points can be taken instead as the point of view, and the whole configuration holds again, relabeled. … In other words, each self sees the same configuration, but labels it differently. I am one of those selves, you are another. … So I guess I can only be remembered, or only hope to be remembered, in this way – as I remember others – as other selves.”

Bob touched the lives of so many people of all ages, and his memory continues to live with us all.

We are collecting stories about him and his impact for a website commemorating his life.
