Members of the REED family are stunned and saddened by news of the death of John Astington, a theater historian who had been a good friend to REED, and to members of the REED family, for decades. John had retired from active teaching at the University of Toronto, but remained fully engaged in his research. He was actively anticipating a visit to London in January when, at the end of October, he began to feel unwell. The discovery that he had an aggressive form of lymphoma came as a shock to him and his family. Though he remained hopeful and in good spirits, the disease took its course with incredible speed, leading to his death on December 11. John will be remembered by associates of REED for his sociability, his irrepressible good humor, his wide-ranging interests, his dedication to theater history and practice, and his distinguished record of academic research and publication.
