Our first meeting with Reuven is a short story in and of itself. Linda Cunningham, a sculptor who once taught at Franklin and Marshall College (of which I am an alumnus) spent time in Berlin on a Fulbright grant during the time that I headed the American Embassy Office there in the 1990s. We became friendly and have remained in touch. Linda invited us to an exhibition opening in Bushwick about four years ago and introduced Carol and me to Sarah, a former colleague at F and M, and Reuven. We all clicked immediately and Reuven invited me to join the cosmology group he was then forming. We met once a month over lunch in a private room in a midtown Irish bar. Although I had no real scientific background, I was interested in the subject, but approached it with some trepidation. Reuven assured me and several others that this was a class for amateurs, no math or science required.
Sarah and several other poets did a delightful reading one evening at the Cornelia Street Cafe and we were so glad to meet them again. Shortly thereafter we had dinner in each other's homes and our friendship was cemented. Reuven loved Sarah's poetry and even read one of her poems about cosmology to our group. He was also very proud of you and Merav and occasionally gave us a glimpse into your work.
I marveled at Reuven's endless curiosity, enthusiasm and energy level. He had a long and very distinguished career and could easily have rested on his laurels; but that was clearly not for him. He loved teaching and was brilliant in explaining to non-scientists concepts and realities which are at the edge of the universe (and of our ability to fathom). Reuven loved his students as much as the subject. Each class began with introductions and catch up on what we had each been doing. Then Reuven would launch into the daily subject with. "Well, it just so happens that . . . , " and we were off. He encouraged interruptions and questions, even as he was a great lecturer. He appreciated the difficulty of the material and often said he would repeat something 100 times, hoping we might finally then get it.
He opened new vistas for me and I now read about subjects I had not previously considered - the big bang, time-space, Einstein, gravitational waves and related topics. He cared about and deeply understood the big questions of the universe and got all of us, his students, to think about them.
On a personal level, Reuven changed my life. I retired shortly before we met, following a career in diplomacy and a second career in the non-profit world. While so much was shut down during the time of covid, Reuven adapted and made his monthly session weekly. With some technical assistance on zoom, his Friday class was a highlight of my week these past eight months.
I loved him, miss him and talk about him every day.
