Jack was a larger than life character both in his Science and his approach to life. We first met over 20 years ago at a scientific meeting in San Francisco. Jack had just published his landmark paper describing the development of functional MRI, I was intrigued by his work, but he was more interested in discussing our work on magnetoencephalography (MEG). That meeting hatched a plan for combining multiple methods for imaging brain function that has been a cornerstone of our collaborative work and discussions ever since.
Jack became a big fan of New Mexico, and for a decade we often would wind up skiing the steeps of Taos or Crested Butte… we never made an oft-discussed spring trip to The Gulch in Vermont. Jack was also an aficionado of flying. We made a number of flights across New Mexico and Colorado, sometimes on a mission, and other times for no particular reason. Over our last few years of late night discussions we often would up on the topic of Jets or helicopters.
On another occasion Jack tried to organize a consortium to buy a classic wood sailing ship. Cooler heads prevailed, but I was very happy to see his photos from last summer, out on Boston harbor in the motor vessel he ultimately acquired.
I was continually struck by Jack's love and admiration for his family. He often spoke of his mother, and was proud of and inspired by her achievement as a pilot, among many other things. He regularly discussed his beloved uncles, and family connections that inspired a dream to establish a scientific institute on Maui, to couple some of his favorite things. He was deeply devoted to his wife, and a daughter who arrived relatively late in life, a continuous source of joy.
We miss Jack, and often think of him as a model of a life fully lived.
