I am deeply saddened to learn of George's passing. I feared the worst when my Christmas e-mail to him bounced this year. George was one of our nation's finest researchers - a national treasure! Not only was he brilliant, but he was also most kind and patient. I was honored to work with George and his team over the years on the dream of low-rate high-quality speech coding. He was always striving for improvements and encouraging all of us all to do likewise. George was a prolific author* and his conference presentations were thrilling. My team, led by Tom Tremain (RIP), frequently drove down the road to visit George and his team at NRL (including Larry Fransen, Stephanie Everett, and Astrid Schmidt-Nielsen). I have fond memories of those visits, where we became friends. Thanks to George's research and research he inspired, the dream of low-rate high-quality speech coding was achieved after decades of research and now it is George's time to rest in peace.
