"He was the first big-time meeting I had at the start of my career," Reynolds wrote, adding that he was "nervous as hell to meet him." "Eric wasn't how I imagined a seriously successful comedy writer. He was so approachable."

He continued: "I traveled all over the world with Eric. He introduced me to Vaudeville and Jack Benny and welcomed me into his friend circle of impossibly talented writers and performers. He was my university. He helped me grow and find my voice. And he did all of it while finding himself. Eric never stopped becoming Eric."

"He was kind. And gentle. And funny as hell," Reynolds wrote. "And incapable of holding a conversation that was cruel or tore someone down. It's a tragedy he's gone and a tragedy more people won't have the chance to know him."
