Mark Hallett

What a shock to learn of Mark´s death! Tobin and I saw Mark infrequently, at Wellesley reunions, but he was always a highlight of our seeing old friends. Judy, we know these are challenging times for you, but you´re so fortunate to have memories of Mark . We´ll miss him in May of next year, but know you´ll carry his spirit forward. We send condolences to you and the whole family. Love, Libbet and Tobin

Sincere condolences to Judy and the family.

Mark and I walked together in the parade of alumni at our 60th Harvard reunion in June 2025. Judy and Mark joined a conversation group of classmates afterwards. What a privilege and a joy to be among their many admirers over a long, productive, deeply humane life.

Our heartfelt condolences to all the members of Mark's family and to all his dear friends who will miss him greatly. His long record of accomplishments will live on -- may his memory always be a blessings -- Sandy and Ray Cypess

The world has a lost a giant in the world of science and a beautiful human being who touched so many lives as mentor, friend, colleague, father, grandfather, and husband. Condolences dear Judy . . .
