Robert Cahen photographed predominantly for the San Francisco Opera, for decades. He adored opera, respected the performers and that showed in his photo studies. He photographed the great of the greats... Callas, DeStefano, Nilsson, Horne, Thomas, Schwarzkopf, Sutherland, Rysanek... to mention a few. He befriended the singers who recognized both his enthusiasm and seriousness. Sadly, Bob passed away this week after being in failing health. We e-mailed up until the end. He always wanted to know what was going on. He was thrilled that Hvorostovsky is here for DeLuna sounding brilliant. Bob was a fun guy, a total opera person. I'll miss the schmoozing.
