We met at UC Berkeley 1960, both age 24, kept up over some East Coast years, settled together at UC Santa Cruz in its infancy, suffered parallel family traumas, grew old together. In my view, he was among the most able math people in our department. We retired together, early, in disgust over the corruption of the university, and then kept in touch these twenty-plus years. I will miss him.

Under a cold winter breeze, in a small rural Jewish cemetery, the sound of thudding dirt falling six feet upon the unremarkable casket whose remains inside we knew as Jay. In his ways, simplicity was akin to his hallmark. He ate when he was hungry, slept when he was tired. Relieved himself weekly of his desires. Worked at his computer when motivated. Sat at the kitchen table in front of his computer for endless hours. His passing a bitter sweet sorrow. And still I am harkened to his affable ways of agreement, “Yes ! Yes!” And we knew a moment of common sharing needed no further words.

Jay was 81 = 3 to the 4th power. He'd have been happy with the number 81. Also, 81 years comes as close as one can get to equaling 1000 moons (lunar orbits of Earth). In India, one thousand moons is celebrated like no solar anniversary.

With his "Euclidean and non-Euclidean geometries" Marvin succeeded in keeping axiomatic geometry alive in a time and place in which it was looked down upon. He took the ethos of the 1970s at UCSC seriously and created a masterpiece with a holistic view of mathematics, trying to make a chapter of the history of mathematics available to those who are willing to embark on the journey. I know that some did, for they were my students.

Jay is acknowledged by mathematicians for having constructed a functor—the "Greenberg functor"—that was used by Serre to prove an important theorem in algebraic geometry. Jay authored a classic text—"Euclidean and Non-Euclidean Geometries"—that has already attained mathematical immortality and will surely confer upon its author a measure of the same.
